Earthquake shaking in the eastern United States can travel much farther and cause damage over larger areas than previously thought.

U.S. Geological Survey scientists found that last year’s magnitude 5.8 earthquake in Virginia triggered landslides at distances four times farther—and over an area 20 times larger—than previous research has shown.

“We used landslides as an example and direct physical evidence to see how far-reaching shaking from east coast earthquakes could be,” said Randall Jibson, USGS scientist and lead author of this study. “Not every earthquake will trigger landslides, but we can use landslide distributions to estimate characteristics of earthquake energy and how far regional ground shaking could occur.”

“Scientists are confirming with empirical data what more than 50 million people in the eastern U.S. experienced firsthand: this was one powerful earthquake,” said USGS Director Marcia McNutt. “Calibrating the distance over which landslides occur may also help us reach back into the geologic record to look for evidence of past history of major earthquakes from the Virginia seismic zone.”

This study will help inform earthquake hazard and risk assessments as well as emergency preparedness, whether for landslides or other earthquake effects.

This study also supports existing research showing that although earthquakes are less frequent in the East, their damaging effects can extend over a much larger area as compared to the western United States.

The research is being presented today at the Geological Society of America conference, and will be published in the December 2012 issue of the Bulletin of the Seismological Society of America.

The USGS found that the farthest landslide from the 2011 Virginia earthquake was 245 km (150 miles) from the epicenter. This is by far the greatest landslide distance recorded from any other earthquake of similar magnitude. Previous studies of worldwide earthquakes indicated that landslides occurred no farther than 60 km (36 miles) from the epicenter of a magnitude 5.8 earthquake.

“What makes this new study so unique is that it provides direct observational evidence from the largest earthquake to occur in more than 100 years in the eastern U.S,” said Jibson. “Now that we know more about the power of East Coast earthquakes, equations that predict ground shaking might need to be revised.”

It is estimated that approximately one-third of the U.S. population could have felt last year’s earthquake in Virginia, more than any earthquake in U.S. history. About 148,000 people reported their ground-shaking experiences caused by the earthquake on the USGS “Did You Feel It?” website. Shaking reports came from southeastern Canada to Florida and as far west as Texas.

In addition to the great landslide distances recorded, the landslides from the 2011 Virginia earthquake occurred in an area 20 times larger than expected from studies of worldwide earthquakes. Scientists plotted the landslide locations that were farthest out and then calculated the area enclosed by those landslides. The observed landslides from last year’s Virginia earthquake enclose an area of about 33,400 km2, while previous studies indicated an expected area of about 1,500 km2 from an earthquake of similar magnitude.

“The landslide distances from last year’s Virginia earthquake are remarkable compared to historical landslides across the world and represent the largest distance limit ever recorded,” said Edwin Harp, USGS scientist and co-author of this study. “There are limitations to our research, but the bottom line is that we now have a better understanding of the power of East Coast earthquakes and potential damage scenarios.”

The difference between seismic shaking in the East versus the West is due in part to the geologic structure and rock properties that allow seismic waves to travel farther without weakening.

Changing Hands Before the Sixth Seal (Revelation 6:12)

Changing Hands at Indian Point?

BY BRIAN PJ CRONIN

DECEMBER 21, 2019

Riverkeeper objects to potential transfer

Entergy is looking to the future of Indian Point and hoping that it no longer includes Entergy.

Last month, the energy company filed an application with the U.S. Nuclear Regulatory Commission to transfer its licenses to operate Indian Point to Holtec International after the shutdown of the last reactor at the nuclear plant, which is scheduled for April 2021.

Holtec would then begin mothballing the facility, using a $2.1 billion decommissioning fund that has been accumulated by Entergy during the life of the plant. Holtec also has said it would hire about 300 Indian Point workers.

“Entergy is in the power-generation business, and decommissioning is a line of work that we’re not involved in,” said Jerry Nappi, an Entergy representative. “Holtec specializes in the management of used fuel and its affiliates have special expertise in decommissioning. They can decommission the plant decades sooner than Entergy would be able to.”

Entergy’s original plan had been to take 60 years, the maximum time allowed by the Nuclear Regulatory Commission; Holtec plans to do it in 15. (Holtec did not respond to a request for comment for this story.)

The accelerated timeline doesn’t concern Richard Webster, the legal director for Riverkeeper, the Ossining-based environmental group. Many decommissioning projects start with a process called SAFSTOR, in which the plant is monitored for up to 45 years to give the radioactive materials time to decay and lower the amount of hazardous material. By skipping SAFSTOR, “15 years is a reasonable amount of time to do it,” said Webster.

Nevertheless, Riverkeeper has asked the Nuclear Regulatory Commission (or, failing that, Gov. Andrew Cuomo) to deny the transfer to Holtec.

“Our objections can be summed up as: Bribes, lies, poor safety record and under-capitalization,” said Webster.

Holtec is no stranger to controversy. In 2010, the inspector general for the Tennessee Valley Authority, a federal agency, found that Holtec had funneled $54,000 to a TVA manager to secure contracts. The firm was fined $2 million and barred from federal contracts for 60 days.

In Ohio, Holtec was awarded tax credits following a 2009 promise to bring 200 jobs to its facility in Orrville. But the jobs never appeared — in fact, the plant lost four positions — and the tax credits were rescinded.

Then, when applying for tax breaks in New Jersey in order to bring a facility to Camden, the company claimed that it had never been barred from working with federal agencies. To push New Jersey to grant the tax breaks, Holtec said Ohio and South Carolina had made generous counterproposals, an assertion both states denied.

Last year, a contractor at the San Onofre nuclear power plant in California, where Holtec has been contracted to manage spent fuel, brought to light an apparent near accident involving a dry cask filled with radioactive fuel. (Plant officials said there was never any danger to the public.) The worker also alleged the site was understaffed and its supervisors often replaced with less experienced managers.

Finally, on the financial side, Webster said he was alarmed at Holtec’s decision at the Oyster Creek nuclear plant in New Jersey, which has been decommissioning for less than a year, to transfer money from the decommissioning fund to spent fuel management, a move that Holtec has signaled it would also do at Indian Point.

“That’s not what that fund is for,” he said. “And there’s a complicated set of LLCs [limited-liability corporations] designed to shield Holtec International, the core corporation. We just don’t have much information about the financial viability [of the company]. If you were running a huge international business that was making money, you shouldn’t be so desperate to get tax breaks that you have to lie on a form.”

At Entergy, Nappi said that Holtec’s recent approvals from the Nuclear Regulatory Commission show that the issues raised aren’t of concern. “The NRC has approved the transactions for two previous nuclear power plants to Holtec, and that only happens if a company can demonstrate that it has the technical and financial qualifications needed,” he said. “We feel confident that Indian Point will receive approval.”

If that happens, Webster said he hoped that it would at least come with certain conditions, such as the creation of a citizens’ oversight committee with the power to (1) audit the decommissioning fund, (2) subpoena documents, (3) have specialists look at difficult situations, and (4) transfer questions of safety to the NRC.

At the least, Webster said, Holtec should not be allowed to keep anything that remains in the decommissioning fund at the end of the project, as it might encourage the firm to do the job as cheaply as possible at the expense of safety and other concerns.

New York Subways at the Sixth Seal (Revelation 6)

How vulnerable are NYC’s underwater subway tunnels to flooding?

Ashley Fetters

New York City is full of peculiar phenomena—rickety fire escapes; 100-year-old subway tunnels; air conditioners propped perilously into window frames—that can strike fear into the heart of even the toughest city denizen. But should they? Every month, writer Ashley Fetters will be exploring—and debunking—these New York-specific fears, letting you know what you should actually worry about, and what anxieties you can simply let slip away.

The 25-minute subway commute from Crown Heights to the Financial District on the 2/3 line is, in my experience, a surprisingly peaceful start to the workday—save for one 3,100-foot stretch between the Clark Street and Wall Street stations, where for three minutes I sit wondering what the probability is that I will soon die a torturous, claustrophobic drowning death right here in this subway car.

The Clark Street Tunnel, opened in 1916, is one of approximately a dozen tunnels that escort MTA passengers from one borough to the next underwater—and just about all of them, with the exception of the 1989 addition of the 63rd Street F train tunnel, were constructed between 1900 and 1936.

Each day, thousands of New Yorkers venture across the East River and back again through these tubes buried deep in the riverbed, some of which are nearing or even past their 100th birthdays. Are they wrong to ponder their own mortality while picturing one of these watery catacombs suddenly springing a leak?

Mostly yes, they are, says Michael Horodniceanu, the former president of MTA Capital Construction and current principal of Urban Advisory Group. First, it’s important to remember that the subway tunnel is built under the riverbed, not just in the river—so what immediately surrounds the tunnel isn’t water but some 25 feet of soil. “There’s a lot of dirt on top of it,” Horodniceanu says. “It’s well into the bed of the bottom of the channel.”

And second, as Angus Kress Gillespie, author of Crossing Under the Hudson: The Story of the Holland and Lincoln Tunnels, points out, New York’s underwater subway tunnels are designed to withstand some leaking. And withstand it they do: Pumps placed below the floor of the tunnel, he says, are always running, always diverting water seepage into the sewers. (Horodniceanu says the amount of water these pumps divert into the sewer system each day numbers in the thousands of gallons.)

Additionally, MTA crews routinely repair the grouting and caulking, and often inject a substance into the walls that creates a waterproof membrane outside the tunnel—which keeps water out of the tunnel and relieves any water pressure acting on its walls. New tunnels, Horodniceanu points out, are even built with an outside waterproofing membrane that works like an umbrella: Water goes around it, it falls to the sides, and then it gets channeled into a pumping station and pumped out.

Of course, the classic New York nightmare scenario isn’t just a cute little trickle finding its way in. The anxiety daydream usually involves something sinister, or seismic. The good news, however, is that while an earthquake or explosion would indeed be bad for many reasons, it likely wouldn’t result in the frantic flooding horror scene that plays out in some commuters’ imaginations.

Horodniceanu assures me that tunnels built more recently are “built to withstand a seismic event.” The older tunnels, however—like, um, the Clark Street Tunnel—“were not seismically retrofitted, let me put it that way,” Horodniceanu says. “But the way they were built is in such a way that I do not believe an earthquake would affect them.” They aren’t deep enough in the ground, anyway, he says, to be too intensely affected by a seismic event. (The MTA did not respond to a request for comment.)

One of the only real threats to tunnel infrastructure, Horodniceanu adds, is extreme weather. Hurricane Sandy, for example, caused flooding in the tunnels, which “created problems with the infrastructure.” He continues, “The tunnels have to be rebuilt as a result of saltwater corroding the infrastructure.”

Still, he points out, hurricanes don’t exactly happen with no warning. So while Hurricane Sandy did cause major trauma to the tunnels, train traffic could be stopped with ample time to keep passengers out of harm’s way. In 2012, Governor Andrew Cuomo directed all the MTA’s mass transit services to shut down at 7 p.m. the night before Hurricane Sandy was expected to hit New York City.

And Gillespie, for his part, doubts even an explosion would result in sudden, dangerous flooding. A subway tunnel is not a closed system, he points out; it’s like a pipe that’s open at both ends. “The force of a blast would go forwards and backwards out the exit,” he says.

So the subway-train version of that terrifying Holland Tunnel flood scene in Sylvester Stallone’s Daylight is … unrealistic, right?

“Yeah,” Gillespie laughs. “Yeah. It is.”

15073790937_a2b5f1e61f_bSloshing of Earth’s core may spike major earthquakes

By Paul VoosenOct. 30, 2017 , 1:45 PM

The number of major earthquakes, like the magnitude-7 one that devastated Haiti in 2010, seems to be correlated with minute fluctuations in day length.

SEATTLE—The world doesn’t stop spinning. But every so often, it slows down. For decades, scientists have charted tiny fluctuations in the length of Earth’s day: Gain a millisecond here, lose a millisecond there. Last week at the annual meeting of the Geological Society of America here, two geophysicists argued that these minute changes could be enough to influence the timing of major earthquakes—and potentially help forecast them.

During the past 100 years, Earth’s slowdowns have correlated surprisingly well with periods with a global increase in magnitude-7 and larger earthquakes, according to Roger Bilham of the University of Colorado (CU) in Boulder and Rebecca Bendick at the University of Montana in Missoula. Usefully, the spike, which adds two to five more quakes than typical, happens well after the slow-down begins. “The Earth offers us a 5-years heads up on future earthquakes, which is remarkable,” says Bilham, who presented the work.

Most seismologists agree that earthquake prediction is a minefield. And so far, Bilham and Bendick have only fuzzy, hard-to-test ideas about what might cause the pattern they found. But the finding is too provocative to ignore, other researchers say. “The correlation they’ve found is remarkable, and deserves investigation,” says Peter Molnar, a geologist also at CU.

The research started as a search for synchrony in earthquake timing. Individual oscillators, be they fireflies, heart muscles, or metronomes, can end up vibrating in synchrony as a result of some kind of cross-talk—or some common influence. To Bendick, it didn’t seem a far jump to consider the faults that cause earthquakes, with their cyclical buildup of strain and violent discharge, as “really noisy, really crummy oscillators,” she says. She and Bilham dove into the data, using the only complete earthquake catalog for the past 100 years: magnitude-7 and larger earthquakes.

In work published in August in Geophysical Research Letters they reported two patterns: First, major quakes appeared to cluster in time

—although not in space. And second, the number of large earthquakes seemed to peak at 32-year intervals. The earthquakes could be somehow talking to each other, or an external force could be nudging the earth into rupture.

Exploring such global forces, the researchers eventually discovered the match with the length of day. Although weather patterns such as El Nino can drive day length to vary back and forth by a millisecond over a year or more, a periodic, decades-long fluctuation of several milliseconds—in particular, its point of peak slow down about every three decades or so—lined up with the quake trend perfectly. “Of course that seems sort of crazy,” Bendick says. But maybe it isn’t. When day length changes over decades, Earth’s magnetic field also develops a temporary ripple. Researchers think slight changes in the flow of the molten iron of the outer core may be responsible for both effects. Just what happens is uncertain—perhaps a bit of the molten outer core sticks to the mantle above. That might change the flow of the liquid metal, altering the magnetic field, and transfer enough momentum between the mantle and the core to affect day length.

Seismologists aren’t used to thinking about the planet’s core, buried 2900 kilometers beneath the crust where quakes happen. But they should, Bilham said during his talk here. The core is “quite close to us. It’s closer than New York from here,” he said.

At the equator, Earth spins 460 meters per second. Given this high velocity, it’s not absurd to think that a slight mismatch in speed between the solid crust and mantle and the liquid core could translate into a force somehow nudging quakes into synchrony, Molnar says. Of course, he adds, “It might be nonsense.” But the evidence for some kind of link is compelling, says geophysicist Michael Manga of the University of California, Berkeley. “I’ve worked on earthquakes triggered by seasonal variation, melting snow. His correlation is much better than what I’m used to seeing.”

One way or another, says James Dolan, a geologist at the University of Southern California in Los Angeles, “we’re going to know in 5 years.” That’s because Earth’s rotation began a periodic slow-down 4-plus years ago. Beginning next year, Earth should expect five more major earthquakes a year than average—between 17 to 20 quakes, compared with the anomalously low four so far this year. If the pattern holds, it will put a new spin on earthquake forecasting.

Decommissioning of Indian Point Plant Not In Time (Revelation 6:12)

Request Made to Accelerate Decommissioning of Indian Pt. Plants

November 26, 2019 By Rick Pezzullo

The owners of the Indian Point nuclear power plants and their chosen successors have requested approval to speed up the decommissioning process.

Entergy Corporation and Holtec International, through their affiliates, announced last week they had jointly filed a License Transfer Application with the U.S. Nuclear Regulatory Commission, requesting approval for the transfer of the NRC licenses for Indian Point to Holtec after the last unit in Buchanan permanently shuts down by April 30, 2021.

Holtec plans to initiate decommissioning at Indian Point, following regulatory approvals and transaction close, as much as 40 years sooner than if Entergy continued to own the units.

“Holtec’s plan to accelerate the decommissioning schedule provides the potential for site redevelopment decades sooner than if Entergy continued to own the facility, which is good news for the local community,” said Chris Bakken, Entergy Executive Vice President Nuclear Operations and Chief Nuclear Officer. “Holtec plans to begin the decommissioning process promptly upon taking ownership, and as part of the agreement between the companies, will provide job opportunities for more than 300 of our current employees who want to remain in the region and continue to work at the site.”

The companies asked the NRC to approve the License Transfer Application by November 2020 to facilitate a timely transaction closing targeted for May 2021, which will benefit the community, employees and other interested stakeholders.

“This key regulatory filing is an important first step to beginning a new future for Indian Point and the local community,” said Holtec’s President and Chief Executive Officer Dr. Kris Singh. “By beginning decommissioning earlier, Holtec will be able to maintain and create new jobs and work towards releasing the plant site earlier so it can be repurposed and generate replacement tax revenue on an earlier schedule.”

In January 2017, Entergy, which purchased the Indian Point nuclear power plants more than 16 years ago, announced, to the complete surprise of local leaders, its plan for the early and orderly shutdown of Indian Point by April 30, 2021 as part of a settlement with New York State and Riverkeeper.

Holtec’s plan for decommissioning will result in the release for re-use of portions of the site in the 2030s, with the exception of the Independent Spent Fuel Storage Installation – the area where spent nuclear fuel is safely stored in dry casks until the U.S. Department of Energy transfers the spent fuel offsite. As part of its plan, Holtec expects to move all of the Indian Point spent nuclear fuel into dry casks within about three years following facility shutdown in 2021.

Holtec has a pending application with the NRC for a Consolidated Interim Storage Facility in New Mexico, which could eventually store spent nuclear fuel from Indian Point and other U.S. nuclear power plants.

Westchester County Executive George Latimer said he and federal representatives are demanding answers on what exactly Holtec has planned for the site.

“In Westchester, we have residents who rightfully demand clear-eyed answers as to what the next steps Holtec have for the plant in our backyard. Further, we have a workforce already here with the expertise – and on the job experience – needed to safely work on this nuclear power plant,” Latimer stated. “The decommissioning process must not be taken lightly nor seen as strictly for profit. I am concerned about how Holtec’s plans will impact both the on-site, knowledgeable workforce and efforts to ensure that the cleanup is undertaken while abiding by the highest environmental standards.”

In addition to the federal filing, Entergy and Holtec filed a petition with the New York Public Service Commission requesting a ruling disclaiming PSC jurisdiction or abstaining from review of the proposed transaction, or, in the alternative, an order approving the proposed transaction.

Historic Earthquakes

Near New York City, New York

1884 08 10 19:07 UTC

Magnitude 5.5

Intensity VII

USGS.gov

This severe earthquake affected an area roughly extending along the Atlantic Coast from southern Maine to central Virginia and westward to Cleveland, Ohio. Chimneys were knocked down and walls were cracked in several States, including Connecticut, New Jersey, New York, and Pennsylvania. Many towns from Hartford, Connecticut, to West Chester,Pennsylvania.

Property damage was severe at Amityville and Jamaica, New York, where several chimneys were “overturned” and large cracks formed in walls. Two chimneys were thrown down and bricks were shaken from other chimneys at Stratford (Fairfield County), Conn.; water in the Housatonic River was agitated violently. At Bloomfield, N.J., and Chester, Pa., several chimneys were downed and crockery was broken. Chimneys also were damaged at Mount Vernon, N.Y., and Allentown, Easton, and Philadelphia, Pa. Three shocks occurred, the second of which was most violent. This earthquake also was reported felt in Vermont, Virginia, and Washington, D.C. Several slight aftershocks were reported on August 11.

New York City is Past Due for an Earthquake

by , 03/22/11

filed under: News

New York City may appear to be an unlikely place for a major earthquake, but according to history, we’re past due for a serious shake. Seismologists at Columbia University’s Lamont-Doherty Earth Observatory say that about once every 100 years, an earthquake of at least a magnitude of 5.0 rocks the Big Apple. The last one was a 5.3 tremor that hit in 1884 — no one was killed, but buildings were damaged.

Any tremor above a 6.0 magnitude can be catastrophic, but it is extremely unlikely that New York would ever experience a quake like the recent 8.9 earthquake in Japan. A study by the Earth Observatory found that a 6.0 quake hits the area about every 670 years, and a 7.0 magnitude hits about every 3,400 years.

There are several fault lines in New York’s metro area, including one along 125th Street, which may have caused two small tremors in 1981 and a 5.2 magnitude quake in 1737. There is also a fault line on Dyckman Street in Inwood, and another in Dobbs Ferry in Westchester County. The New York City Area Consortium for Earthquake Loss Mitigation rates the chance of an earthquake hitting the city as moderate.

John Armbruster, a seismologist at the Earth Observatory, said that if a 5.0 magnitude quake struck New York today, it would result in hundreds of millions, possibly billions of dollars in damages. The city’s skyscrapers would not collapse, but older brick buildings and chimneys would topple, likely resulting in casualities.

The Earth Observatory is expanding its studies of potential earthquake damage to the city. They currently have six seismometers at different landmarks throughout the five boroughs, and this summer, they plan to place one at the arch in Washington Square Park and another in Bryant Park.

Won-Young Kim, who works alongside Armbuster, says his biggest concern is that we can’t predict when an earthquake might hit. “It can happen anytime soon,” Kim told the Metro. If it happened tomorrow, he added, “I would not be surprised. We can expect it any minute, we just don’t know when and where.”

Armbuster voiced similar concerns to the Daily News. “Will there be one in my lifetime or your lifetime? I don’t know,” he said. “But this is the longest period we’ve gone without one.”

The Ramapo Fault and the Sixth Seal (Revelation 6:12)

Living on the Fault Line

Posted June 15, 2010 by Wayne J. Guglielmo

The couple checked with Burns’s parents, who live in nearby Basking Ridge, and they, too, had heard and felt something, which they thought might have been an earthquake. A call by Burns some 20 minutes later to the Bernardsville Police Department—one of many curious and occasionally panicky inquiries that Sunday morning, according to the officer in charge, Sergeant John Remian—confirmed their suspicion: A magnitude 2.6 earthquake, its epicenter in Peapack/Gladstone, about seven miles from Bernardsville, had hit the area. A smaller aftershock followed about two and a half hours later.

After this year’s epic earthquakes in Haiti, Chile, Mexico, Indonesia, and China, the 2.6 quake and aftershock that shook parts of New Jersey in February may seem minor league, even to the Somerset County residents who experienced them. On the exponential Richter Scale, a magnitude 7.0 quake like the one that hit Haiti in January is almost 4 million times stronger than a quake of 2.6 magnitude. But comparisons of magnitude don’t tell the whole story.

Northern New Jersey straddles the Ramapo Fault, a significant ancient crack in the earth’s crust. The longest fault in the Northeast, it begins in Pennsylvania and moves into New Jersey, trending northeast through Hunterdon, Somerset, Morris, Passaic, and Bergen counties before terminating in New York’s Westchester County, not far from the Indian Point Energy Center, a nuclear power plant. And though scientists dispute how active this roughly 200 million-year-old fault really is, many earthquakes in the state’s surprisingly varied seismic history are believed to have occurred on or near it. The fault line is visible at ground level and likely extends as deep as nine miles below the surface.

During the past 230 years or so, New Jersey has been at the epicenter of nearly 170 earthquakes, according to data compiled by the New Jersey Geological Survey, part of the United States Department of Environmental Protection. The largest known quake struck in 1783, somewhere west of New York City, perhaps in Sussex County. It’s typically listed as 5.3 in magnitude, though that’s an estimate by seismologists who are quick to point out that the concept of magnitude—measuring the relative size of an earthquake—was not introduced until 1935 by Charles Richter and Beno Gutenberg. Still, for quakes prior to that, scientists are not just guessing.

“We can figure out the damage at the time by going back to old records and newspaper accounts,” says Won-Young Kim, a senior research scientist at Columbia University’s Lamont-Doherty Earth Observatory in Palisades, New York, directly across the New Jersey border. “Once the amount and extent of contemporary damage has been established,” Kim says, “we’re then able to gauge the pattern of ground shaking or intensity of the event—and from there extrapolate its probable magnitude.”

Other earthquakes of magnitude 5 or higher have been felt in New Jersey, although their epicenters laying near New York City. One—which took place in 1737 and was said to have been felt as far north as Boston and as far south as northern Delaware—was probably in the 5 to 5.5 range. In 1884, an earthquake of similar magnitude occurred off New York’s Rockaway Beach. This well-documented event pulled houses off their foundations and caused steeples to topple as far west as Rahway. The shock wave, scientists believe, was felt over 70,000 square miles, from Vermont to Maryland.

Among the largest sub-5 magnitude earthquakes with epicenters in New Jersey, two (a 3.8 and a 4.0) took place on the same day in 1938 in the Lakehurst area in Ocean County. On August 26, 2003, a 3.5 magnitude quake shook the Frenchtown/Milford area in Hunterdon County. On February 3 of last year, a 3.0 magnitude quake occurred in the Morris County town of Mendham. “A lot of people felt this one because of the intense shaking, although the area of intensity wasn’t very wide,” says Lamont-Doherty’s Kim, who visited the site after the event.

After examining the known historical and geological record, Kim and other seismologists have found no clear evidence that an earthquake of greater than 5.3 to 5.5 magnitude has taken place in this area going back to 1737. This doesn’t mean, of course, that one did not take place in the more remote past or that one will not occur in the future; it simply means that a very large quake is less likely to occur here than in other places in the east where the seismic hazard is greater, including areas in South Carolina and northeastern New York State.

Given this low-hazard, high-vulnerability scenario, how far along are scientists in their efforts to predict larger magnitude earthquakes in the New Jersey area? The answer is complex, complicated by the state’s geographical position, its unique geological history, the state of seismology itself, and the continuing debate over the exact nature and activity of the Ramapo Fault.

Over millions of years, New Jersey developed four distinct physiographic provinces or regions, which divide the state into a series of diagonal slices, each with its own terrain, rock type, and geological landforms.

The northernmost slice is the Valley and Ridge, comprising major portions of Sussex and Warren counties. The southernmost slice is the Coastal Plain, a huge expanse that covers some three-fifths of the state, including all of the Shore counties. Dividing the rest of the state are the Highlands, an area for the most part of solid but brittle rock right below the Valley and Ridge, and the lower lands of the Piedmont, which occupy all of Essex, Hudson, and Union counties, most of Bergen, Hunterdon, and Somerset, and parts of Middlesex, Morris, and Passaic.

For earthquake monitors and scientists, the formation of these last two provinces—the Highlands and the Piedmont—are of special interest. To understand why, consider that prior to the appearance of the Atlantic Ocean, today’s Africa was snuggled cozily up against North America and surrounded by a single enormous ocean. “At that point, you could have had exits off the New Jersey Turnpike for Morocco,” says Alexander Gates, professor of geology and chair of the department of Earth and Environmental Sciences at Rutgers-Newark.

Under the pressure of circulating material within the Earth’s super-hot middle layer, or mantle, what was once a single continent—one that is thought to have included today’s other continents as well—began to stretch and eventually break, producing numerous cracks or faults and ultimately separating to form what became the Atlantic Ocean. In our area, the longest and most active of these many cracks was the Ramapo Fault, which, through a process known as normal faulting, caused one side of the earth’s crust to slip lower—the Piedmont—relative to the other side—the Highlands. “All this occurred about 225 million years ago,” says Gates. “Back then, you were talking about thousands of feet between the Highlands and the Piedmont and a very active Ramapo Fault.”

The Earth’s crust, which is 20 to 25 miles thick, is not a single, solid shell, but is broken into seven vast tectonic plates, which drift atop the soft, underlying mantle. Although the northeast-trending Ramapo Fault neatly divides two of New Jersey’s four physiographic provinces, it does not form a so-called plate boundary, as does California’s infamous San Andreas Fault. As many Californians know all too well, this giant fault forms the boundary between two plates—to the west, the Pacific Plate, and to the east, the North American Plate; these rub up against each other, producing huge stresses and a regularly repeating pattern of larger earthquakes.

This second bit of uncertainty is especially troubling for some people, including some in the media who want a neat story. To get around it, they ignore the differences between plate settings and link all of New Jersey’s earthquakes, either directly or implicitly, to the Ramapo Fault. In effect, such people want the Ramapo Fault “to look like the San Andreas Fault,” says Gates. “They want to be able to point to one big fault that’s causing all of our earthquakes.”

Gates does not think that’s the case, and he has been working with colleagues for a number of years to prove it. “What we have found is that there are smaller faults that generally cut from east to west across the northeast-trending Ramapo Fault,” he explains. “These much smaller faults are all over the place, and they’re actually the ones that are the active faults in the area.”

But what mechanisms are responsible for the formation of these apparently active auxiliary faults? One such mechanism, say scientists, is the westward pressure the Atlantic Ocean exerts on the North American Plate, which for the most part resists any movement. “I think we are in an equilibrium state most of the time,” says Lamont-Doherty’s Kim.

Still, that continuous pressure on the plate we sit on causes stress, and when that stress builds up sufficiently, the earth’s crust has a tendency to break around any weak zones. In our area, the major weak zone is the Ramapo Fault—“an ancient zone of weakness,” as Kim calls it. That zone of weakness exacerbates the formation of auxiliary faults, and thereby the series of minor earthquakes the state has experienced over the years.

All this presupposes, of course, that any intraplate stress in this area will continue to be released gradually, in a series of relatively minor earthquakes or releases of energy. But what if that were not the case? What if the stress continued to build up, and the release of large amounts of energy came all at once? In crude terms, that’s part of the story behind the giant earthquakes that rocked what is now New Madrid, Missouri, between 1811 and 1812. Although estimates of their magnitude have been revised downward in recent years to less than magnitude 8, these earthquakes are generally regarded as among the largest intraplate events to have occurred in the continental United States.

For a number of reasons—including the relatively low odds that the kind of stored energy that unleashed the New Madrid events could ever build up here—earthquakes of plus-6 magnitude are probably not in our future. Still, says Kim, even a magnitude 6 earthquake in certain areas of the state could do considerable damage, especially if its intensity or ground shaking was of sufficient strength. In a state as geologically diverse and densely populated as New Jersey, this is a crucial wild card.

Part of the job of the experts at the New Jersey Geological Survey is to assess the seismic hazards in different parts of the state. To do this, they use a computer-simulation model developed under the direction of the Federal Emergency Management Agency, known as HAZUS, for Hazards US. To assess the amount of ground shaking likely to occur in a given county during events ranging in magnitude from 5 to 7 on the Richter Scale, NJGS scientists enter three features of a county’s surface geology into their computer model. Two of these features relate to the tendency of soil in a given area to lose strength, liquefy, or slide downhill when shaken. The third and most crucial feature has to do with the depth and density of the soil itself and the type of bedrock lying below it; this is a key component in determining a region’s susceptibility to ground shaking and, therefore, in estimating the amount of building and structural damage that’s likely to occur in that region. Estimates for the various counties—nine to date have been studied—are sent to the New Jersey Office of Emergency Management, which provided partial funding for the project.

To appreciate why this element of ground geology is so crucial to earthquake modelers, consider the following: An earthquake’s intensity—which is measured on something called the Modified Mercalli Scale—is related to a number of factors. The amount of energy released or the magnitude of an event is clearly a big factor. But two earthquakes of the same magnitude can have very different levels of intensity; in fact, it’s quite possible for a lower magnitude event to generate more ground shaking than a higher magnitude one.

In addition to magnitude, other factors that affect intensity are the distance of the observer or structure from the epicenter, where intensity is the greatest; the depth beneath the surface of the initial rupture, with shallower ruptures producing more ground shaking than deeper ones; and, most significantly, the ground geology or material that the shock wave generated by the earthquake must pass through.

As a rule, softer materials like sand and gravel shake much more intensely than harder materials, because the softer materials are comparatively inefficient energy conductors, so whatever energy is released by the quake tends to be trapped, dispersing much more slowly. (Think of a bowl of Jell-O on a table that’s shaking.)

In contrast, harder materials, like the solid rock found widely in the Highlands, are brittle and break under pressure, but conduct energy well, so that even big shock waves disperse much more rapidly through them, thereby weakening the amount of ground shaking. “If you’ve read any stories about the 1906 earthquake in San Francisco, you know the most intense damage was in those flat, low areas by the Bay, where the soil is soft, and not in the hilly, rocky areas above,” says Karl Muessig, state geologist and NJGS head.

The map that accompanies the online version of the NJGS’s Earthquake Loss Estimation Study divides the state’s surface geology into five seismic soil classes, ranging from Class A, or hard rock, to Class E, or soft soil (state.nj.us/dep/njgs/enviroed/hazus.htm).

Although the weakest soils are scattered throughout the state, including the Highlands, which besides harder rock also contains areas of glacial lakes, clays, and wetlands, they are most evident in the Piedmont and the Coastal Plain. “The largest expanses of them are in coastal areas where you have salt marshes or large glacial lakes, as in parts of the Passaic River basin,” says Scott Stanford, a research scientist with NJGS and lead author of the estimate. Some of the very weakest soils, Stanford adds, are in areas of filled marshland, including places along the Hudson waterfront, around Newark Bay and the Meadowlands, and along the Arthur Kill.

Faults in these areas—and in the coastal plain generally—are far below the ground, perhaps several hundred to a thousand feet down, making identification difficult. “There are numerous faults upon which you might get earthquake movement that we can’t see, because they’re covered by younger sediments,” Stanford says.

This combination of hidden faults and weak soils worries scientists, who are all too aware that parts of the coastal plain and Piedmont are among the most densely populated and developed areas in the state. (The HAZUS computer model also has a “built environment” component, which summarizes, among other things, types of buildings in a given area.) For this reason, such areas would be in the most jeopardy in the event of a large earthquake.

For example, in the study’s loss estimate for Essex County, which includes Newark, the state’s largest city, a magnitude 6 event would result in damage to 81,600 buildings, including almost 10,000 extensively or completely; 36,000 people either displaced from their homes or forced to seek short-term shelter; almost $9 million in economic losses from property damage and business interruption; and close to 3,300 injuries and 50 fatalities. (The New York City Area Consortium for Earthquake Loss Mitigation has conducted a similar assessment for New York City, at nycem.org.)

All of this suggests the central irony of New Jersey geology: The upland areas that are most prone to earthquakes—the counties in or around the Ramapo Fault, which has spawned a network of splays, or auxiliary faults—are much less densely populated and sit, for the most part, on good bedrock. These areas are not invulnerable, certainly, but, by almost all measures, they would not sustain very severe damage, even in the event of a higher magnitude earthquake. The same can’t be said for other parts of the state, where the earthquake hazard is lower but the vulnerability far greater. Here, the best we can do is to prepare—both in terms of better building codes and a constantly improving emergency response.

Meanwhile, scientists like Rutgers’s Gates struggle to understand the Earth’s quirky seismic timetable: “The big thing with earthquakes is that you can commonly predict where they are going to occur,” Gates says. “When they’re going to come, well, we’re nowhere near being able to figure that out.”

***********************

For the men and women of the state police who manage and support the New Jersey Office of Emergency Management (OEM), the response to some events, like hurricanes, can be marshalled in advance. But an earthquake is what responders call a no-notice event.

In New Jersey, even minor earthquakes—like the one that shook parts of Somerset County in February—attract the notice of local, county, and OEM officials, who continuously monitor events around the state from their Regional Operations and Intelligence Center (The ROIC) in West Trenton, a multimillion dollar command-and-control facility that has been built to withstand 125 mph winds and a 5.5 magnitude earthquake. In the event of a very large earthquake, during which local and county resources are apt to become quickly overwhelmed, command and control authority would almost instantly pass to West Trenton.

Here, officials from the state police, representatives of a galaxy of other state agencies, and a variety of communications and other experts would assemble in the cavernous and ultra-high tech Emergency Operations Center to oversee the state’s response. “A high-level earthquake would definitely cause the governor to declare a state of emergency,” says OEM public information officer Nicholas J. Morici. “And once that takes place, our emergency operations plan would be put in motion.”

Emergency officials have modeled that plan—one that can be adapted to any no-notice event, including a terrorist attack—on response methodologies developed by the Federal Emergency Management Agency (FEMA), part of the U.S. Department of Homeland Security. At its core is a series of seventeen emergency support functions, ranging from transportation to firefighting, debris removal, search and rescue, public health, and medical services. A high-magnitude event would likely activate all of these functions, says Morici, along with the human and physical resources needed to carry them out—cranes and heavy trucks for debris removal, fire trucks and teams for firefighting, doctors and EMTs for medical services, buses and personnel carriers for transportation, and so on.

This is where an expert like Tom Rafferty comes in. Rafferty is a Geographic Information Systems Specialist attached to the OEM. His job during an emergency is to keep track electronically of which resources are where in the state, so they can be deployed quickly to where they are needed. “We have a massive database called the Resource Directory Database in which we have geolocated municipal, county, and state assets to a very detailed map of New Jersey,” Rafferty says. “That way, if there is an emergency like an earthquake going on in one area, the emergency managers can quickly say to me, for instance, ‘We have major debris and damage on this spot of the map. Show us the location of the nearest heavy hauler. Show us the next closest location,’ and so on.”

A very large quake, Rafferty says, “could overwhelm resources that we have as a state.” In that event, OEM has the authority to reach out to FEMA for additional resources and assistance. It can also call upon the private sector—the Resource Directory has been expanded to include non-government assets—and to a network of volunteers. “No one has ever said, ‘We don’t want to help,’” Rafferty says. New Jersey officials can also request assistance through the Emergency Management Assistance Compact (EMAC), an agreement among the states to help each other in times of extreme crisis.

“You always plan for the worst,” Rafferty says, “and that way when the worst doesn’t happen, you feel you can handle it if and when it does.”

Indian Point is NOT radiologically ready for the Sixth Seal

With Indian Point, are you radiologically ready?

By Thomas Slater Emergency Preparedness Coordinator

August 23rd, 2018 | NewsNews and Features

Just as there are plans in place for dealing with natural emergencies such as tropical and winter storms, readiness plans are developed for man-made emergencies, which includes radiological hazards.

Nuclear power plants operate in most states in the country and produce about 20 percent of the nation’s power.

Nearly three million people live within the 10-mile Emergency Planning Zone of an operating nuclear power plant, including West Point, which is situated between 7-to-9 miles from the Indian Point Energy Center (IPEC) in Buchanan of Westchester County.

Although the construction and operation of nuclear power plants are closely monitored and regulated by the Nuclear Regulatory Commission, incidents at these plants are possible—and planned for.

If an accident at IPEC were to result in the potential or actual release of radiation, warning sirens in the area would be activated. Commercial and West Point media sources would broadcast Emergency Alert System  messages to advise you on protective measures.

Depending upon the scope and scale of the emergency, protective actions may include “shelter-in-place” or “evacuation” advisories. As radioactive materials rapidly decay and dissipate with distance, the most likely scenario for West Point personnel would be to take shelter rather than trying to evacuate.

If you are instructed to shelter-in-place, the following steps will keep you and your family safe during the emergency.

• Shelter. Go inside your home or the nearest building; choose an inside room with as few windows or doors as possible.

• Shut. Shut and lock all windows and doors to create a better seal; turn off heating or cooling ventilation systems. If at home, make sure the fireplace damper and all ventilation fans are closed.

• Listen. Local officials are your best source of information. If in an office, monitor your computer, television and phones; if at home, listen to your radio or television until you are told it is safe to leave the shelter or to evacuate.

For more details, consult the Orange County Indian Point Emergency Guide, available at https://www.orangecountygov.com/DocumentCenter/View/2368/Indian-Point-Orange-Emergency-Guide-PDF, or call the West Point Emergency Manager at 845-938-7092.

Readiness, through education and preparation, is the best defense. Are you radiological ready?

NEW YORK IS 40 YEARS OVERDUE A MAJOR EARTHQUAKE AND AMERICA ISN’T PROPERLY PREPARED, ‘QUAKELAND’ AUTHOR KATHRYN MILES TELLS TREVOR NOAH

BY TUFAYEL AHMED ON 9/27/17 AT 9:28 AM

Updated | An earthquake is long overdue to hit New York and America isn’t prepared, author and environmental theorist Kathryn Miles told Trevor Noah on Tuesday’s Daily Show.

Miles is the author of a new book, Quakeland, which investigates how imminently an earthquake is expected in the U.S. and how well-prepared the country is to handle it. The answer to those questions: Very soon and not very well.

“We know it will, that’s inevitable, but we don’t know when,” said Miles when asked when to expect another earthquake in the U.S.

She warned that New York is in serious danger of being the site of the next one, surprising considering that the West Coast sits along the San Andreas fault line.

“New York is 40 years overdue for a significant earthquake…Memphis, Seattle, Washington D.C.—it’s a national problem,” said Miles.

Miles told Noah that though the U.S. is “really good at responding to natural disasters,” like the rapid response to the hurricanes in Texas and Florida, the country and its government is, in fact, lagging behind in its ability to safeguard citizens before an earthquake hits.

“We’re really bad at the preparedness side,” Miles responded when Noah asked how the infrastructure in the U.S. compares to Mexico’s national warning system, for example.

“Whether it’s the literal infrastructure, like our roads and bridges, or the metaphoric infrastructure, like forecasting, prediction, early warning systems. Historically, we’ve underfunded those and as a result we’re way behind even developing nations on those fronts.”

Part of the problem, Miles says, is that President Donald Trump and his White House are not concerned with warning systems that could prevent the devastation of natural disasters.

“We can invest in an early warning system. That’s one thing we can definitely do. We can invest in better infrastructures, so that when the quake happens, the damage is less,” said the author.

“The scientists, the emergency managers, they have great plans in place. We have the technology for an early warning system, we have the technology for tsunami monitoring. But we don’t have a president that is currently interested in funding that, and that’s a problem.”

This article has been updated to reflect that Miles said New York is the possible site of an upcoming earthquake, and not the likeliest place to be next hit by one.
