New York City Is Overdue For Large Earthquake: Seismologist

http://www.gothamgazette.com/graphics/2008/09/skyesfig3_cropped.gif

Won-Young Kim, who runs the seismographic network for the Northeast at Columbia University’s Lamont-Doherty Earth Observatory, said the city is well overdue for a big earthquake.

The last big quake to hit New York City was a 5.3-magnitude tremor in 1884 that happened at sea in between Brooklyn and Sandy Hook. While no one was killed, buildings were damaged.

Kim said the city is likely to experience a big earthquake every 100 years or so.

“It can happen anytime soon,” Kim said. “We can expect it any minute, we just don’t know when and where.”

New York has never experienced a magnitude 6 or 7 earthquake, which are the most dangerous. But magnitude 5 quakes could topple brick buildings and chimneys.

Seismologist John Armbruster said a magnitude 5 quake that happened now would be more devastating than the one that happened in 1884.

Authorities Expecting The Sixth Seal? (Revelation 6:12)

New York Times

By SAM ROBERTS

JULY 17, 2014

Here is another reason to buy a mega-million-dollar apartment in a Manhattan high-rise: Earthquake forecast maps for New York City that a federal agency issued on Thursday indicate “a slightly lower hazard for tall buildings than previously thought.”

The agency, the United States Geodetic Survey, tempered its latest quake prediction with a big caveat.

Federal seismologists based their projections of a lower hazard for tall buildings — “but still a hazard nonetheless,” they cautioned — on a lower likelihood of slow shaking from an earthquake occurring near the city, the type of shaking that typically causes more damage to taller structures.

“The tall buildings in Manhattan are not where you should be focusing,” said John Armbruster, a seismologist with the Lamont-Doherty Earth Observatory of Columbia University. “They resonate with long period waves. They are designed and engineered to ride out an earthquake. Where you should really be worried in New York City is the common brownstone and apartment building and buildings that are poorly maintained.”

Mr. Armbruster was not involved in the federal forecast, but was an author of an earlier study that suggested that “a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed.”

He noted that barely a day goes by without a New York City building’s being declared unsafe, without an earthquake. “If you had 30, 40, 50 at one time, responders would be overloaded,” he said.

The city does have an earthquake building code that went into effect in 1996, and that applies primarily to new construction.

A well-maintained building would probably survive a magnitude 5 earthquake fairly well, he said. The last magnitude 5 earthquake in the city struck in 1884. Another is not necessarily inevitable; faults are more random and move more slowly than they do in, say, California. But he said the latest federal estimate was probably raised because of the magnitude of the Virginia quake.

Mr. Armbruster said the Geodetic Survey forecast would not affect his daily lifestyle. “I live in a wood-frame building with a brick chimney and I’m not alarmed sitting up at night worried about it,” he said. “But society’s leaders need to take some responsibility.”

Quakeland: On the Road to America’s Next Devastating Earthquake

Roger Bilham

Given recent seismic activity — political as well as geological — it’s perhaps unsurprising that two books on earthquakes have arrived this season. One is as elegant as the score of a Beethoven symphony; the other resembles a diary of conversations overheard during a rock concert. Both are interesting, and both relate recent history to a shaky future.

Journalist Kathryn Miles’s Quakeland is a litany of bad things that happen when you provoke Earth to release its invisible but ubiquitous store of seismic-strain energy, either by removing fluids (oil, water, gas) or by adding them in copious quantities (when extracting shale gas in hydraulic fracturing, also known as fracking, or when injecting contaminated water or building reservoirs). To complete the picture, she describes at length the bad things that happen during unprovoked natural earthquakes. As its subtitle hints, the book takes the form of a road trip to visit seismic disasters both past and potential, and seismologists and earthquake engineers who have first-hand knowledge of them. Their colourful personalities, opinions and prejudices tell a story of scientific discovery and engineering remedy.

Miles poses some important societal questions. Aside from human intervention potentially triggering a really damaging earthquake, what is it actually like to live in neighbourhoods jolted daily by magnitude 1–3 earthquakes, or the occasional magnitude 5? Are these bumps in the night acceptable? And how can industries that perturb the highly stressed rocks beneath our feet deny obvious cause and effect? In 2015, the Oklahoma Geological Survey conceded that a quadrupling of the rate of magnitude-3 or more earthquakes in recent years, coinciding with a rise in fracking, was unlikely to represent a natural process. Miles does not take sides, but it’s difficult for the reader not to.

She visits New York City, marvelling at subway tunnels and unreinforced masonry almost certainly scheduled for destruction by the next moderate earthquake in the vicinity. She considers the perils of nuclear-waste storage in Nevada and Texas, and ponders the risks to Idaho miners of rock bursts — spontaneous fracture of the working face when the restraints of many million years of confinement are mined away. She contemplates the ups and downs of the Yellowstone Caldera — North America’s very own mid-continent supervolcano — and its magnificently uncertain future. Miles also touches on geothermal power plants in southern California’s Salton Sea and elsewhere; the vast US network of crumbling bridges, dams and oil-storage farms; and the magnitude 7–9 earthquakes that could hit California and the Cascadia coastline of Oregon and Washington state this century. Amid all this doom, a new elementary school on the coast near Westport, Washington, vulnerable to inbound tsunamis, is offered as a note of optimism. With foresight and much persuasion from its head teacher, it was engineered to become an elevated safe haven.

Miles briefly discusses earthquake prediction and the perils of getting it wrong (embarrassment in New Madrid, Missouri, where a quake was predicted but never materialized; prison in L’Aquila, Italy, where scientists failed to foresee a devastating seismic event) and the successes of early-warning systems, with which electronic alerts can be issued ahead of damaging seismic waves. Yes, it’s a lot to digest, but most of the book obeys the laws of physics, and it is a engaging read. One just can’t help wishing that Miles’s road trips had taken her somewhere that wasn’t a disaster waiting to happen.

Catastrophic damage in Anchorage, Alaska, in 1964, caused by the second-largest earthquake in the global instrumental record.

In The Great Quake, journalist Henry Fountain provides us with a forthright and timely reminder of the startling historical consequences of North America’s largest known earthquake, which more than half a century ago devastated southern Alaska. With its epicentre in Prince William Sound, the 1964 quake reached magnitude 9.2, the second largest in the global instrumental record. It released more energy than either the 2004 Sumatra–Andaman earthquake or the 2011 Tohoku earthquake off Japan; and it generated almost as many pages of scientific commentary and description as aftershocks. Yet it has been forgotten by many.

The quake was scientifically important because it occurred at a time when plate tectonics was in transition from hypothesis to theory. Fountain expertly traces the theory’s historical development, and how the Alaska earthquake was pivotal in nailing down one of the most important predictions. The earthquake caused a fjordland region larger than England to subside, and a similarly huge region of islands offshore to rise by many metres; but its scientific implications were not obvious at the time. Eminent seismologists thought that a vertical fault had slipped, drowning forests and coastlines to its north and raising beaches and islands to its south. But this kind of fault should have reached the surface, and extended deep into Earth’s mantle. There was no geological evidence of a monster surface fault separating these two regions, nor any evidence for excessively deep aftershocks. The landslides and liquefied soils that collapsed houses, and the tsunami that severely damaged ports and infrastructure, offered no clues to the cause.

“Previous earthquakes provide clear guidance about present-day vulnerability.” The hero of The Great Quake is the geologist George Plafker, who painstakingly mapped the height reached by barnacles lifted out of the intertidal zone along shorelines raised by the earthquake, and documented the depths of drowned forests. He deduced that the region of subsidence was the surface manifestation of previously compressed rocks springing apart, driving parts of Alaska up and southwards over the Pacific Plate. His finding confirmed a prediction of plate tectonics, that the leading edge of the Pacific Plate plunged beneath the southern edge of Alaska along a gently dipping thrust fault. That observation, once fully appreciated, was applauded by the geophysics community.

Fountain tells this story through the testimony of survivors, engineers and scientists, interweaving it with the fascinating history of Alaska, from early discovery by Europeans to purchase from Russia by the United States in 1867, and its recent development. Were the quake to occur now, it is not difficult to envisage that with increased infrastructure and larger populations, the death toll and price tag would be two orders of magnitude larger than the 139 fatalities and US$300-million economic cost recorded in 1964.

What is clear from these two books is that seismicity on the North American continent is guaranteed to deliver surprises, along with unprecedented economic and human losses. Previous earthquakes provide clear guidance about the present-day vulnerability of US infrastructure and populations. Engineers and seismologists know how to mitigate the effects of future earthquakes (and, in mid-continent, would advise against the reckless injection of waste fluids known to trigger earthquakes). It is merely a matter of persuading city planners and politicians that if they are tempted to ignore the certainty of the continent’s seismic past, they should err on the side of caution when considering its seismic future.

New Study: America Overdue For Major Earthquake … In States You Didn’t Suspect

Written by: Daniel Jennings Current Events

The survey’s new National Seismic Hazard Map show that the risk of earthquakes in parts of the country — such as the Midwest, Oregon and the Rocky Mountains — is far higher than previously thought. All total, Americans in one-third of the country saw their risk for an earthquake increase.

“I worry that we will wake up one morning and see earthquake damage in our country that is as bad as that has occurred in some developing nations that have experienced large earthquakes,” Carl Hedde, a risk management expert at insurer Munich Reinsurance America, said of the map in The Wall Street Journal. “Beyond building collapse, a large amount of our infrastructure could be immediately damaged. Our roads, bridges and energy transmission systems can be severely impacted.”

Among the findings:

  • The earthquake danger in parts of Missouri, Arkansas, Tennessee, Illinois and South Carolina is as high as that in Los Angeles.
  • 42 of the 50 states have a reasonable chance of experiencing a damaging earthquake in the next 50 years.
  • Parts of 16 states have the highest risk of a quake: Alaska, Hawaii, California, Oregon, Washington, Nevada, Utah, Idaho, Montana, Wyoming, Missouri, Arkansas, Tennessee, Illinois, Kentucky and South Carolina

“We know the hazard has increased for small and moderate size earthquakes,” USGS scientist William Ellsworth told The Journal. “We don’t know as well how much the hazard has increased for large earthquakes. Our suspicion is it has but we are working on understanding this.”

Frightening Results From New Study

The USGS used new computer modeling technology and data collected from recent quakes such as the one that struck Washington, D.C. in 2011 to produce the new maps. The maps show that many Americans who thought they were safe from earthquakes are not.

Some of the survey’s other disturbing findings include:

    • The earthquake danger in Oklahoma, Alabama, Colorado, Georgia, Indiana, Michigan, Virginia, New York and parts of New England is higher than previously thought.
    • Some major metropolitan areas, including Memphis, Salt Lake City, Seattle, St. Louis and Charleston, have a higher risk of earthquakes than previously thought. One of the nation’s most dangerous faults, the New Madrid fault, runs right through St. Louis and Missouri. It is the nation’s second most active fault. On Dec. 16, 1811, the New Madrid Fault was the site of the most powerful series of earthquakes in American history.

“Obviously the building codes throughout the central U.S. do not generally take earthquake risk or the risk of a large earthquake into account,” USGS Seismologist Elizabeth Cochran told The Journal. Her take: Earthquake damage in the central US could be far greater than in places like California, because structures in some locations are not built to withstand quakes.

Others agree.

“Earthquakes are quite rare in many places but when they happen they cause very intense damage because people have not prepared,” Mark Petersen, the project chief for the USGS’s National Seismic Hazard Map, told The Journal.

This new map should be a wakeup call for Americans.

History Expects the Sixth Seal in NYC (Revelation 6:12)

According to the New York Daily News, Lynn Skyes, lead author of a recent study by seismologists at the Lamont-Doherty Earth Observatory adds that a magnitude-6 quake hits the area about every 670 years, and magnitude-7 every 3,400 years.

A 5.2-magnitude quake shook New York City in 1737 and another of the same severity hit in 1884.

Tremors were felt from Maine to Virginia.

There are several fault lines in the metro area, including one along Manhattan’s 125th St. – which may have generated two small tremors in 1981 and may have been the source of the major 1737 earthquake, says Armbruster.

“The problem here comes from many subtle faults,” explained Skyes after the study was published.

He adds: “We now see there is earthquake activity on them. Each one is small, but when you add them up, they are probably more dangerous than we thought.”

Armbruster says a 5.0-magnitude earthquake today likely would result in casualties and hundreds of millions of dollars in damage.

“I would expect some people to be killed,” he notes.

The scope and scale of damage would multiply exponentially with each additional tick on the Richter scale. (ANI)

NYC earthquake risk: the Sixth Seal (Revelation 6:12)

NYC earthquake risk: Could Staten Island be heavily impacted?

By Ann Marie Barron

Updated May 16, 4:31 AM; Posted May 16, 4:00 AM

STATEN ISLAND, N.Y. – While scientists say it’s impossible to predict when or if an earthquake will occur in New York City, they say that smaller structures — like Staten Island’s bounty of single-family homes — will suffer more than skyscrapers if it does happen.

„Earthquakes in the East tend to cause higher-frequency shaking — faster back-and-forth motion — compared to similar events in the West,“ according to a report by the U.S. Geological Survey (USGS), published on its website recently „Shorter structures are more susceptible to damage during fast shaking, whereas taller structures are more susceptible during slow shaking.“

DIFFERENCES IN INTENSITY

The report, „East vs West Coast Earthquakes,“ explains how USGS scientists are researching factors that influence regional differences in the intensity and effects of earthquakes, and notes that earthquakes in the East are often felt at more than twice the distance of earthquakes in the West.

Predicting when they will occur is more difficult, said Thomas Pratt, a research geophysicist and the central and Eastern U.S. coordinator for the USGS Earthquake Hazards Program in Reston, Va.

„One of the problems in the East Coast is that we don’t have a history to study,“ he said. „In order to get an idea, we have to have had several cycles of these things. The way we know about them in California is we dig around in the mud and we see evidence of past earthquakes.“

Yet Pratt wouldn’t rule out the possibility of a high-magnitude event taking place in New York, which sits in the middle the North American Tectonic Plate, considered by experts to be quite stable.

„We never know,“ he said. „One could come tomorrow. On the other hand, it could be another 300 years. We don’t understand why earthquakes happen (here) at all.“

Though the city’s last observable earthquake occurred on Oct. 27, 2001, and caused no real damage, New York has been hit by two Magnitude 5 earthquakes in its history – in 1738 and in 1884 — prompting many to say it is „due“ for another.

While earthquakes generally have to be Magnitude 6 or higher to be considered „large,“ by experts, „a Magnitude 5, directly under New York City, would shake it quite strongly,“ Pratt said.

The reason has to do with the rock beneath our feet, the USGS report says.

OLDER ROCKS

In the East, we have older rocks, some of which formed „hundreds of millions of years before those in the West,“ the report says. Since the faults in the rocks have had so much time to heal, the seismic waves travel more efficiently through them when an earthquake occurs.

„Rocks in the East are like a granite countertop and rocks in the West are much softer,“ Pratt said. „Take a granite countertop and hit it and it’ll transmit energy well. In the West, it’s like a sponge. The  energy gets absorbed.“

If a large, Magnitude 7 earthquake does occur, smaller structures, and older structures in Manhattan would be most vulnerable, Pratt said. „In the 1920s, ’30s and late 1800s, they were not built with earthquake resistance,“ he said, noting that newer skyscrapers were built to survive hurricanes, so would be more resistant.

When discussing earthquake prediction and probability, Pratt uses the analogy of a baseball player who averages a home run every 10 times at bat and hasn’t hit one in the past nine games: „When he’s up at bat, will he hit a home run? You just don’t know.“

And though it would probably take a magnitude of 7 to topple buildings in the city, smaller earthquakes are still quite dangerous, he said.

„Bookshelves could fall down and hit you,“ he said. „People could be killed.“ A lot of stone work and heavy objects fell from buildings when a quake of 5.8 magnitude struck central Virginia in 2011, he noted, but, fortunately, no one was injured.

To be safe, Pratt encourages New Yorkers to keep a few days‘ worth of drinking water and other supplies on hand. He, himself, avoids putting heavy things up high.

„It always gets me nervous when I go into a restaurant that has heavy objects high on shelves,“ he said. „It’s unlikely you’ll get an earthquake. But, we just don’t know.“
