From Wikipedia, the free encyclopedia

Although the eastern United States is not as seismically active as regions near plate boundaries, large and damaging earthquakes do occur there. Furthermore, when these rare eastern U.S. earthquakes occur, the areas affected by them are much larger than for western U.S. earthquakes of the same magnitude.[1] Thus, earthquakes represent at least a moderate hazard to East Coast cities, including New York City and adjacent areas of very high population density.
As can be seen in the maps of earthquake activity in this region, seismicity is scattered throughout most of the New York City area, with some hint of a concentration of earthquakes in the area surrounding Manhattan Island. The largest known earthquake in this region occurred in 1884 and had a magnitude of approximately 5. For this earthquake, observations of fallen bricks and cracked plaster were reported from eastern Pennsylvania to central Connecticut, and the maximum intensity reported was at two sites in western Long Island (Jamaica, New York and Amityville, New York). Two other earthquakes of approximately magnitude 5 occurred in this region in 1737 and 1783.[2][3][4] The figure on the right shows maps of the distribution of earthquakes of magnitude 3 and greater that occurred in this region from 1924 to 2010, along with locations of the larger earthquakes that occurred in 1737, 1783 and 1884.
Background
The NYC area is part of the geologically complex structure of the Northern Appalachian Mountains. This complex structure was formed during the past half billion years when the Earth’s crust underlying the Northern Appalachians was the site of two major geological episodes, each of which has left its imprint on the NYC area bedrock.[5][6] Between about 450 million years ago and about 250 million years ago, the Northern Appalachian region was affected by a continental collision, in which the ancient African continent collided with the ancient North American continent to form the supercontinent Pangaea. Beginning about 200 million years ago, the present-day Atlantic ocean began to form as plate tectonic forces began to rift apart the continent of Pangaea. The last major episode of geological activity to affect the bedrock in the New York area occurred about 100 million years ago, during the Mesozoic era, when continental rifting that led to the opening of the present-day Atlantic ocean formed the Hartford and Newark Mesozoic rift basins.
Earthquake rates in the northeastern United States are about 50 to 200 times lower than in California, but the earthquakes that do occur in the northeastern U.S. are typically felt over a much broader region than earthquakes of the same magnitude in the western U.S.[1] This means the area of damage from an earthquake in the northeastern U.S. could be larger than the area of damage caused by an earthquake of the same magnitude in the western U.S.[7] The cooler rocks in the northeastern U.S. contribute to the seismic energy propagating as much as ten times further than in the warmer rocks of California. A magnitude 4.0 eastern U.S. earthquake typically can be felt as far as 100 km (60 mi) from its epicenter, but it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake, although uncommon, can be felt as far as 500 km (300 mi) from its epicenter, and can cause damage as far away as 40 km (25 mi) from its epicenter. Earthquakes stronger than about magnitude 5.0 generate ground motions that are strong enough to be damaging in the epicentral area.
At well-studied plate boundaries like the San Andreas fault system in California, scientists can often make observations that allow them to identify the specific fault on which an earthquake took place. In contrast, east of the Rocky Mountains this is rarely the case.[8] The NYC area is far from the boundaries of the North American plate, which are in the center of the Atlantic Ocean, in the Caribbean Sea, and along the west coast of North America. The seismicity of the northeastern U.S. is generally considered to be due to ancient zones of weakness that are being reactivated in the present-day stress field. In this model, pre-existing faults that were formed during ancient geological episodes persist in the intraplate crust, and the earthquakes occur when the present-day stress is released along these zones of weakness. The stress that causes the earthquakes is generally considered to be derived from present-day rifting at the Mid-Atlantic ridge.
Earthquakes and geologically mapped faults in the Northeastern U.S.
The northeastern U.S. has many known faults, but virtually all of the known faults have not been active for perhaps 90 million years or more. Also, the locations of the known faults are not well determined at earthquake depths. Accordingly, few (if any) earthquakes in the region can be unambiguously linked to known faults. Given the current geological and seismological data, it is difficult to determine if a known fault in this region is still active today and could produce a modern earthquake. As in most other areas east of the Rocky Mountains, the best guide to earthquake hazard in the northeastern U.S. is probably the locations of the past earthquakes themselves.[9]
The Ramapo fault and other New York City area faults
The Ramapo Fault, which marks the western boundary of the Newark rift basin, has been argued to be a major seismically active feature of this region,[10] but it is difficult to discern the extent to which the Ramapo fault (or any other specific mapped fault in the area) might be any more of a source of future earthquakes than any other parts of the region.[11] The Ramapo Fault zone spans more than 185 miles (300 kilometers) in New York, New Jersey, and Pennsylvania. It is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east.[12] This fault is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its vicinity. Recently, public knowledge about the fault has increased – especially after the 1970s, when the fault’s proximity to the Indian Point nuclear plant in New York was noticed.
There is insufficient evidence to unequivocally demonstrate any strong correlation of earthquakes in the New York City area with specific faults or other geologic structures in this region. The damaging earthquake affecting New York City in 1884 was probably not associated with the Ramapo fault because the strongest shaking from that earthquake occurred on Long Island (quite far from the trace of the Ramapo fault). The relationship between faults and earthquakes in the New York City area is currently understood to be more complex than any simple association of a specific earthquake with a specific mapped fault.[13]
A 2008 study argued that a magnitude 6 or 7 earthquake might originate from the Ramapo fault zone,[3] which would almost definitely spawn hundreds or even thousands of fatalities and billions of dollars in damage.[14] Studying around 400 earthquakes over the past 300 years, the study also argued that there was an additional fault zone extending from the Ramapo Fault zone into southwestern Connecticut. As can be seen in the above figure of seismicity, earthquakes are scattered throughout this region, with no particular concentration of activity along the Ramapo fault, or along the hypothesized fault zone extending into southwestern Connecticut.[2][11][15]
Just off the northern terminus of the Ramapo fault is the Indian Point Nuclear Power Plant, built between 1956 and 1960 by Consolidated Edison Company. The plant began operating in 1963, and it has been the subject of a controversy over concerns that an earthquake from the Ramapo fault will affect the power plant. Whether or not the Ramapo fault actually does pose a threat to this nuclear power plant remains an open question.[11]

“You can be forgiven,” writes Kathryn Miles in Quakeland (Aug. 29), “for thinking that the ground beneath your feet is solid.” Yet it isn’t, and by the end of her reporting readers will feel a bit unsteady.

The concerns at the core of Quakeland are that seismologists know the most about the potential earthquakes that are the least alarming, and that we all know little about quakes to begin with. They remain the least predictable of natural disasters and possibly the most catastrophic.
Miles renders a map of other endangered municipalities, like the Oklahoma city that houses tanks containing tens of millions of barrels of oil, in a state where quakes are increasing. Or the stretches of Mississippi River communities where survivors would struggle to receive relief depending on how one bridge fares. Or the several states where the mining and oil- and gas-drilling industries are causing more and more unnatural quakes and whose paychecks allow impoverished people to buy houses their work could end up cleaving. There are also plausible not-even-worst-case scenarios where thousands die, hundreds of thousands become homeless and billions of dollars’ worth of property and resources disintegrate — and that’s only for the known seismic faults. Scientists worry more about the many they have yet to find.
That fear you feel? It’s intended. Miles prefers the most provocative possibilities as Quakeland seeks to rattle us free of the ignorance, uncertainty and short memory that have paralyzed plans for prevention and survival.

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.

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.

The Sixth Seal: More Than Just Manhattan (Revelation 6:12)

New York, NY – In a Quake, Brooklyn Would Shake More Than Manhattan

The Sixth Seal

The Sixth Seal

By Brooklyn Eagle
New York, NY – The last big earthquake in the New York City area, centered in New York Harbor just south of Rockaway, took place in 1884 and registered 5.2 on the Richter Scale. Another earthquake of this size can be expected and could be quite damaging, says Dr. Won-Young Kim, senior research scientist at the Lamont-Doherty Earth Observatory of Columbia University.
And Brooklyn, resting on sediment, would shake more than Manhattan, built on solid rock. “There would be more shaking and more damage,” Dr. Kim told the Brooklyn Eagle on Wednesday.
If an earthquake of a similar magnitude were to happen today near Brooklyn, “Many chimneys would topple. Poorly maintained buildings would fall down – some buildings are falling down now even without any shaking. People would not be hit by collapsing buildings, but they would be hit by falling debris. We need to get some of these buildings fixed,” he said.
But a 5.2 is “not comparable to Haiti,” he said. “That was huge.” Haiti’s devastating earthquake measured 7.0.
Brooklyn has a different environment than Haiti, and that makes all the difference, he said. Haiti is situated near tectonic plate boundaries, while Brooklyn is inside the North American plate, far from its boundary.
“The Caribbean plate is moving to the east, while the North American plate is moving towards the west. They move about 20 mm – slightly less than an inch – every year.” The plates are sliding past each other, and the movement is not smooth, leading to jolts, he said.
While we don’t have the opportunity for a large jolt in Brooklyn, we do have small, frequent quakes of a magnitude of 2 or 3 on the Richter Scale. In 2001 alone the city experienced two quakes: one in January, measuring 2.4, and one in October, measuring 2.6. The October quake, occurring soon after Sept. 11 terrorist attacks, “caused a lot of panic,” Dr. Kim said.
“People ask me, ‘Should I get earthquake insurance?’ I tell them no, earthquake insurance is expensive. Instead, use that money to fix chimneys and other things. Rather than panicky preparations, use common sense to make things better.”
Secure bookcases to the wall and make sure hanging furniture does not fall down, Dr. Kim said. “If you have antique porcelains or dishes, make sure they’re safely stored. In California, everything is anchored to the ground.”
While a small earthquake in Brooklyn may cause panic, “In California, a quake of magnitude 2 is called a micro-quake,” he added.

Don’t Forget About the Sixth Seal (Revelation 6:12)

Don’t forget about earthquakes, feds tell city

Although New York’s modern skyscrapers are less likely to be damaged in an earthquake than shorter structures, a new study suggests the East Coast is more vulnerable than previously thought. The new findings will help alter building codes.

New York Earthquake Hazard

New York Earthquake Hazard

The U.S. Geological Survey had good and bad news for New Yorkers on Thursday. In releasing its latest set of seismic maps the agency said earthquakes are a slightly lower hazard for New York City’s skyscrapers than previously thought, but on the other hand noted that the East Coast may be able to produce larger, more dangerous earthquakes than previous assessments have indicated.
The 2014 maps were created with input from hundreds of experts from across the country and are based on much stronger data than the 2008 maps, said Mark Petersen, chief of the USGS National Seismic Hazard Mapping Project. The bottom line for the nation’s largest city is that the area is at a slightly lower risk for the types of slow-shaking earthquakes that are especially damaging to tall spires of which New York has more than most places, but the city is still at high risk due to its population density and aging structures, said Mr. Petersen.
“Many of the overall patterns are the same in this map as in previous maps,” said Mr. Petersen. “There are large uncertainties in seismic hazards in the eastern United States. [New York City] has a lot of exposure and some vulnerability, but people forget about earthquakes because you don’t see damage from ground shaking happening very often.”
Just because they’re infrequent doesn’t mean that large and potentially disastrous earthquakes can’t occur in the area. The new maps put the largest expected magnitude at 8, significantly higher than the 2008 peak of 7.7 on a logarithmic scale. The scientific understanding of East Coast earthquakes has expanded in recent years thanks to a magnitude 5.8 earthquake in Virginia in 2011 that was felt by tens of millions of people across the eastern U.S. New data compiled by the nuclear power industry has also helped experts understand quakes.
“The update shows New York at an intermediate level,” said Arthur Lerner-Lam, deputy director of Columbia’s Lamont-Doherty Earth Observatory. “You have to combine that with the exposure of buildings and people and the fragility of buildings and people. In terms of safety and economics, New York has a substantial risk.”
Oddly enough, it’s not the modern tall towers that are most at risk. Those buildings become like inverted pendulums in the high frequency shakes that are more common on the East Coast than in the West. But the city’s old eight- and 10-story masonry structures could suffer in a large quake, said Mr. Lerner-Lam. Engineers use maps like those released on Thursday to evaluate the minimum structural requirements at building sites, he said. The risk of an earthquake has to be determined over the building’s life span, not year-to-year.
“If a structure is going to exist for 100 years, frankly, it’s more than likely it’s going to see an earthquake over that time,” said Mr. Lerner-Lam. “You have to design for that event.”
The new USGS maps will feed into the city’s building-code review process, said a spokesman for the New York City Department of Buildings. Design provisions based on the maps are incorporated into a standard by the American Society of Civil Engineers, which is then adopted by the International Building Code and local jurisdictions like New York City. New York’s current provisions are based on the 2010 standards, but a new edition based on the just-released 2014 maps is due around 2016, he said.
“The standards for seismic safety in building codes are directly based upon USGS assessments of potential ground shaking from earthquakes, and have been for years,” said Jim Harris, a member and former chair of the Provisions Update Committee of the Building Seismic Safety Council, in a statement.
The seismic hazard model also feeds into risk assessment and insurance policies, according to Nilesh Shome, senior director of Risk Management Solutions, the largest insurance modeler in the industry. The new maps will help the insurance industry as a whole price earthquake insurance and manage catastrophic risk, said Mr. Shome. The industry collects more than $2.5 billion in premiums for earthquake insurance each year and underwrites more than $10 trillion in building risk, he said.
“People forget about history, that earthquakes have occurred in these regions in the past, and that they will occur in the future,” said Mr. Petersen. “They don’t occur very often, but the consequences and the costs can be high.”

Earthquake rates in the northeastern United States are about 50 to 200 times lower than in California, but the earthquakes that do occur in the northeastern U.S. are typically felt over a much broader region than earthquakes of the same magnitude in the western U.S.[1] This means the area of damage from an earthquake in the northeastern U.S. could be larger than the area of damage caused by an earthquake of the same magnitude in the western U.S.[7] The cooler rocks in the northeastern U.S. contribute to the seismic energy propagating as much as ten times further than in the warmer rocks of California. A magnitude 4.0 eastern U.S. earthquake typically can be felt as far as 100 km (60 mi) from its epicenter, but it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake, although uncommon, can be felt as far as 500 km (300 mi) from its epicenter, and can cause damage as far away as 40 km (25 mi) from its epicenter. Earthquakes stronger than about magnitude 5.0 generate ground motions that are strong enough to be damaging in the epicentral area.
At well-studied plate boundaries like the San Andreas fault system in California, scientists can often make observations that allow them to identify the specific fault on which an earthquake took place. In contrast, east of the Rocky Mountains this is rarely the case.[8] The NYC area is far from the boundaries of the North American plate, which are in the center of the Atlantic Ocean, in the Caribbean Sea, and along the west coast of North America. The seismicity of the northeastern U.S. is generally considered to be due to ancient zones of weakness that are being reactivated in the present-day stress field. In this model, pre-existing faults that were formed during ancient geological episodes persist in the intraplate crust, and the earthquakes occur when the present-day stress is released along these zones of weakness. The stress that causes the earthquakes is generally considered to be derived from present-day rifting at the Mid-Atlantic ridge.
Earthquakes and geologically mapped faults in the Northeastern U.S.
The northeastern U.S. has many known faults, but virtually all of the known faults have not been active for perhaps 90 million years or more. Also, the locations of the known faults are not well determined at earthquake depths. Accordingly, few (if any) earthquakes in the region can be unambiguously linked to known faults. Given the current geological and seismological data, it is difficult to determine if a known fault in this region is still active today and could produce a modern earthquake. As in most other areas east of the Rocky Mountains, the best guide to earthquake hazard in the northeastern U.S. is probably the locations of the past earthquakes themselves.[9]
The Ramapo fault and other New York City area faults
The Ramapo Fault, which marks the western boundary of the Newark rift basin, has been argued to be a major seismically active feature of this region,[10] but it is difficult to discern the extent to which the Ramapo fault (or any other specific mapped fault in the area) might be any more of a source of future earthquakes than any other parts of the region.[11] The Ramapo Fault zone spans more than 185 miles (300 kilometers) in New York, New Jersey, and Pennsylvania. It is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east.[12] This fault is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its vicinity. Recently, public knowledge about the fault has increased – especially after the 1970s, when the fault’s proximity to the Indian Point nuclear plant in New York was noticed.
There is insufficient evidence to unequivocally demonstrate any strong correlation of earthquakes in the New York City area with specific faults or other geologic structures in this region. The damaging earthquake affecting New York City in 1884 was probably not associated with the Ramapo fault because the strongest shaking from that earthquake occurred on Long Island (quite far from the trace of the Ramapo fault). The relationship between faults and earthquakes in the New York City area is currently understood to be more complex than any simple association of a specific earthquake with a specific mapped fault.[13]
A 2008 study argued that a magnitude 6 or 7 earthquake might originate from the Ramapo fault zone,[3] which would almost definitely spawn hundreds or even thousands of fatalities and billions of dollars in damage.[14] Studying around 400 earthquakes over the past 300 years, the study also argued that there was an additional fault zone extending from the Ramapo Fault zone into southwestern Connecticut. As can be seen in the above figure of seismicity, earthquakes are scattered throughout this region, with no particular concentration of activity along the Ramapo fault, or along the hypothesized fault zone extending into southwestern Connecticut.[2][11][15]
Just off the northern terminus of the Ramapo fault is the Indian Point Nuclear Power Plant, built between 1956 and 1960 by Consolidated Edison Company. The plant began operating in 1963, and it has been the subject of a controversy over concerns that an earthquake from the Ramapo fault will affect the power plant. Whether or not the Ramapo fault actually does pose a threat to this nuclear power plant remains an open question.[11]

History Says Expect The Sixth Seal In New York (Revelation 6:12)

Fault Lines In New York City

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)

The Sixth Seal: More Than Just Manhattan (Revelation 6:12)

New York, NY – In a Quake, Brooklyn Would Shake More Than Manhattan

And Brooklyn, resting on sediment, would shake more than Manhattan, built on solid rock. “There would be more shaking and more damage,” Dr. Kim told the Brooklyn Eagle on Wednesday.
If an earthquake of a similar magnitude were to happen today near Brooklyn, “Many chimneys would topple. Poorly maintained buildings would fall down – some buildings are falling down now even without any shaking. People would not be hit by collapsing buildings, but they would be hit by falling debris. We need to get some of these buildings fixed,” he said.
But a 5.2 is “not comparable to Haiti,” he said. “That was huge.” Haiti’s devastating earthquake measured 7.0.
Brooklyn has a different environment than Haiti, and that makes all the difference, he said. Haiti is situated near tectonic plate boundaries, while Brooklyn is inside the North American plate, far from its boundary.
“The Caribbean plate is moving to the east, while the North American plate is moving towards the west. They move about 20 mm – slightly less than an inch – every year.” The plates are sliding past each other, and the movement is not smooth, leading to jolts, he said.
While we don’t have the opportunity for a large jolt in Brooklyn, we do have small, frequent quakes of a magnitude of 2 or 3 on the Richter Scale. In 2001 alone the city experienced two quakes: one in January, measuring 2.4, and one in October, measuring 2.6. The October quake, occurring soon after Sept. 11 terrorist attacks, “caused a lot of panic,” Dr. Kim said.
“People ask me, ‘Should I get earthquake insurance?’ I tell them no, earthquake insurance is expensive. Instead, use that money to fix chimneys and other things. Rather than panicky preparations, use common sense to make things better.”
Secure bookcases to the wall and make sure hanging furniture does not fall down, Dr. Kim said. “If you have antique porcelains or dishes, make sure they’re safely stored. In California, everything is anchored to the ground.”
While a small earthquake in Brooklyn may cause panic, “In California, a quake of magnitude 2 is called a micro-quake,” he added.
