New York Quakes

Most New Yorkers probably view the idea of a major earthquake hitting New York City as a plot device for a second-rate disaster movie. In a city where people worry about so much — stock market crashes, flooding, a terrorist attack — earthquakes, at least, do not have to be on the agenda.
A recent report by leading seismologists associated with Columbia University, though, may change that. The report concludes a serious quake is likely to hit the area.
The implication of this finding has yet to be examined. Although earthquakes are uncommon in the area relative to other parts of the world like California and Japan, the size and density of New York City puts it at a higher risk of damage. The type of earthquake most likely to occur here would mean that even a fairly small event could have a big impact.
The issue with earthquakes in this region is that they tend to be shallow and close to the surface,” explains Leonardo Seeber, a coauthor of the report. “That means objects at the surface are closer to the source. And that means even small earthquakes can be damaging.”
The past two decades have seen an increase in discussions about how to deal with earthquakes here. The most recent debate has revolved around the Indian Point nuclear power plant, in Buchanan, N.Y., a 30-mile drive north of the Bronx, and whether its nuclear reactors could withstand an earthquake. Closer to home, the city adopted new codes for its buildings even before the Lamont report, and the Port Authority and other agencies have retrofitted some buildings. Is this enough or does more need to be done? On the other hand, is the risk of an earthquake remote enough that public resources would be better spent addressing more immediate — and more likely — concerns?

Assessing the Risk

The report by scientists from the Lamont-Doherty Earth Observatory at Columbia University at summarizes decades of information on earthquakes in the area gleaned from a network of seismic instruments, studies of earthquakes from previous centuries through archival material like newspaper accounts and examination of fault lines.
The city can expect a magnitude 5 quake, which is strong enough to cause damage, once every 100 years, according to the report. (Magnitude is a measure of the energy released at the source of an earthquake.) The scientists also calculate that a magnitude 6, which is 10 times larger, has a 7 percent chance of happening once every 50 years and a magnitude 7 quake, 100 times larger, a 1.5 percent chance. Nobody knows the last time New York experienced quakes as large as a 6 or 7, although if once occurred it must have taken place before 1677, since geologists have reviewed data as far back as that year.
The last magnitude 5 earthquake in New York City hit in 1884, and it occurred off the coast of Rockaway Beach. Similar earthquakes occurred in 1737 and 1783.
By the time of the 1884 quake, New York was already a world class city, according to Kenneth Jackson, editor of The Encyclopedia of New York City.”In Manhattan,” Jackson said, “New York would have been characterized by very dense development. There was very little grass.”
A number of 8 to 10 story buildings graced the city, and “in world terms, that’s enormous,” according to Jackson. The city already boasted the world’s most extensive transportation network, with trolleys, elevated trains and the Brooklyn Bridge, and the best water system in the country. Thomas Edison had opened the Pearl Street power plant two years earlier.
All of this infrastructure withstood the quake fairly well. A number of chimneys crumbled and windows broke, but not much other damage occurred. Indeed, the New York Times reported that people on the Brooklyn Bridge could not tell the rumble was caused by anything more than the cable car that ran along the span.

Risks at Indian Point

As dense as the city was then though, New York has grown up and out in the 124 years since. Also, today’s metropolis poses some hazards few, if any people imagined in 1884.
In one of their major findings, the Lamont scientists identified a new fault line less than a mile from Indian Point. That is in addition to the already identified Ramapo fault a couple of miles from the plant. This is seen as significant because earthquakes occur at faults and are the most powerful near them.
This does not represent the first time people have raised concerns about earthquakes near Indian Point. A couple of years after the licenses were approved for Indian Point 2 in 1973 and Indian Point 3 in 1975, the state appealed to the Atomic Safety and Licensing Appeal Panel over seismic issues. The appeal was dismissed in 1976, but Michael Farrar, one of three members on the panel, dissented from his colleagues.
He thought the commission had not required the plant to be able to withstand the vibration that could occur during an earthquake. “I believe that an effort should be made to ascertain the maximum effective acceleration in some other, rational, manner,” Farrar wrote in his dissenting opinion. (Acceleration measures how quickly ground shaking speeds up.)
Con Edison, the plants’ operator at the time, agreed to set up seismic monitoring instruments in the area and develop geologic surveys. The Lamont study was able to locate the new fault line as a result of those instruments.
Ironically, though, while scientists can use the data to issue reports — the federal Nuclear Regulatory Commission cannot use it to determine whether the plant should have its license renewed. The Nuclear Regulatory Commission only considers the threat of earthquakes or terrorism during initial licensing hearings and does not revisit the issue during relicensing.
Lynn Sykes, lead author of the Lamont report who was also involved in the Indian Point licensing hearings, disputes that policy. The new information, he said, should be considered — “especially when considering a 20 year license renewal.”
The state agrees. Last year, Attorney General Andrew Cuomo began reaching out to other attorneys general to help convince the commission to include these risks during the hearings.
Cuomo and the state Department of Environmental Conservation delivered a 312-page petition to the commission that included reasons why earthquakes posed a risk to the power plants. The petition raised three major concerns regarding Indian Point:

  • The seismic analysis for Indian Point plants 2 and 3 did not consider decommissioned Indian Point 1. The state is worried that something could fall from that plant and damage the others.
  • The plant operators have not updated the facilities to address 20 years of new seismic data in the area.
  • The state contends that Entergy, the plant’s operator, has not been forthcoming. “It is not possible to verify either what improvements have been made to [Indian Point] or even to determine what improvements applicant alleges have been implemented,” the petition stated.

A spokesperson for Entergy told the New York Times that the plants are safe from earthquakes and are designed to withstand a magnitude 6 quake.
Lamont’s Sykes thinks the spokesperson must have been mistaken. “He seems to have confused the magnitude scale with intensity scale,” Sykes suggests. He points out that the plants are designed to withstand an event on the intensity scale of VII, which equals a magnitude of 5 or slightly higher in the region. (Intensity measures the effects on people and structures.) A magnitude 6 quake, in Sykes opinion, would indeed cause damage to the plant.
The two reactors at Indian Point generate about 10 percent of the state’s electricity. Since that power is sent out into a grid, it isn’t known how much the plant provides for New York City. Any abrupt closing of the plant — either because of damage or a withdrawal of the operating license — would require an “unprecedented level of cooperation among government leaders and agencies,” to replace its capacity, according to a 2006 report by the National Academies’ National Research Council, a private, nonprofit institution chartered by Congress.

Indian Point Nuclear Plant

Indian Point Nuclear Plant
Entergy’s Indian Point Energy Center, a three-unit nuclear power plant north of New York City, lies within two miles of the Ramapo Seismic Zone.

Beyond the loss of electricity, activists worry about possible threats to human health and safety from any earthquake at Indian Point. Some local officials have raised concerns that radioactive elements at the plant, such as tritium and strontium, could leak through fractures in bedrock and into the Hudson River. An earthquake could create larger fractures and, so they worry, greater leaks.
In 2007, an earthquake hit the area surrounding Japan’s Kashiwazaki-Kariwa nuclear power plant, the world’s largest. The International Atomic Energy Agency determined “there was no significant damage to the parts of the plant important to safety,” from the quake. According to the agency, “The four reactors in operation at the time in the seven-unit complex shut down safely and there was a very small radioactive release well below public health and environmental safety limits.” The plant, however, remains closed.

Shaking the Streets

A quake near Indian Point would clearly have repercussions for New York City. But what if an earthquake hit one of the five boroughs?
In 2003, public and private officials, under the banner of the New York City Area Consortium for Earthquake Loss Mitigation, released a study of what would happen if a quake hit the metropolitan area today. Much of the report focused on building damage in Manhattan. It used the location of the 1884 quake, off the coast of Rockaway Beach, as its modern muse.
If a quake so serious that it is expected to occur once every 2,500 years took place off Rockaway, the consortium estimated it would cause $11.5 billion in damage to buildings in Manhattan. About half of that would result from damage to residential buildings. Even a moderate magnitude 5 earthquake would create an estimated 88,000 tons of debris (10,000 truckloads), which is 136 times the garbage cleared in Manhattan on an average day, they found.
The report does not estimate possible death and injury for New York City alone. But it said that, in the tri-state area as a whole, a magnitude 5 quake could result in a couple of dozen deaths, and a magnitude 7 would kill more than 6,500 people.
Ultimately, the consortium decided retrofitting all of the city’s buildings to prepare them for an earthquake would be “impractical and economically unrealistic,” and stressed the importance of identifying the most vulnerable areas of the city.
Unreinforced brick buildings, which are the most common type of building in Manhattan, are the most vulnerable to earthquakes because they do not absorb motion as well as more flexible wood and steel buildings. Structures built on soft soil are more also prone to risk since it amplifies ground shaking and has the potential to liquefy during a quake.
This makes the Upper East Side the most vulnerable area of Manhattan, according to the consortium report. Because of the soil type, the ground there during a magnitude 7 quake would shake at twice the acceleration of that in the Financial District. Chinatown faces considerable greater risk for the same reasons.
The city’s Office of Emergency Management agency does offer safety tips for earthquakes. It advises people to identify safe places in their homes, where they can stay until the shaking stops, The agency recommends hiding under heavy furniture and away from windows and other objects that could fall.
A special unit called New York Task Force 1 is trained to find victims trapped in rubble. The Office of Emergency Management holds annual training events for the unit.
The Buildings Department created its first seismic code in 1995. More recently, the city and state have adopted the International Building Code (which ironically is a national standard) and all its earthquake standards. The “international” code requires that buildings be prepared for the 2,500-year worst-case scenario.

Transportation Disruptions

With the state’s adoption of stricter codes in 2003, the Port Authority went back and assessed its facilities that were built before the adoption of the code, including bridges, bus terminals and the approaches to its tunnels. The authority decided it did not have to replace any of this and that retrofitting it could be done at a reasonable cost.
The authority first focused on the approaches to bridges and tunnels because they are rigid and cannot sway with the earth’s movement. It is upgrading the approaches to the George Washington Bridge and Lincoln Tunnel so they will be prepared for a worst-case scenario. The approaches to the Port Authority Bus Terminal on 42nd Street are being prepared to withstand two thirds of a worst-case scenario.
The terminal itself was retrofitted in 2007. Fifteen 80-foot tall supports were added to the outside of the structure.
A number of the city’s bridges could be easily retrofitted as well “in an economical and practical manner,” according to a study of three bridges by the consulting firm Parsons Brinckerhoff. Those bridges include the 102nd Street Bridge in Queens, and the 145th Street and Macombs Dam bridges, which span the Harlem River. To upgrade the 155th Street Viaduct, the city will strengthen its foundation and strengthen its steel columns and floor beams.
The city plans upgrades for the viaduct and the Madison Avenue bridge in 2010. The 2008 10-year capital strategy for the city includes $596 million for the seismic retrofitting of the four East River bridges, which is planned to begin in 2013. But that commitment has fluctuated over the years. In 2004, it was $833 million.
For its part, New York City Transit generally is not considering retrofitting its above ground or underground structures, according to a report presented at the American Society of Civil Engineers in 2004. New facilities, like the Second Avenue Subway and the Fulton Transit Center will be built to new, tougher standards.
Underground infrastructure, such as subway tunnels, electricity systems and sewers are generally safer from earthquakes than above ground facilities. But secondary effects from quakes, like falling debris and liquefied soil, could damage these structures.
Age and location — as with buildings — also add to vulnerability. “This stuff was laid years ago,” said Rae Zimmerman, professor of planning and public administration at New York University. “A lot of our transit infrastructure and water pipes are not flexible and a lot of the city is on sandy soil.” Most of Lower Manhattan, for example, is made up of such soil.
She also stresses the need for redundancy, where if one pipe or track went down, there would be another way to go. “The subway is beautiful in that respect,” she said. “During 9/11, they were able to avoid broken tracks.”

Setting Priorities

The city has not made preparing its infrastructure for an earthquake a top priority — and some experts think that makes sense.
“On the policy side, earthquakes are a low priority,” said Guy Nordenson, a civil engineer who was a major proponent of the city’s original seismic code, “and I think that’s a good thing.” He believes there are more important risks, such as dealing with the effects of climate change.
“There are many hazards, and any of these hazards can be as devastating, if not more so, than earthquakes,” agreed Mohamed Ettouney, who was also involved in writing the 1995 seismic code.
In fact, a recent field called multi-hazard engineering has emerged. It looks at the most efficient and economical way to prepare for hazards rather than preparing for all at once or addressing one hazard after the other. For example, while addressing one danger (say terrorism) identified as a priority, it makes sense to consider other threats that the government could prepare for at the same time (like earthquakes).
Scientists from Lamont-Doherty are also not urging anybody to rush to action in panic. Their report is meant to be a first step in a process that lays out potential hazards from earthquakes so that governments and businesses can make informed decisions about how to reduce risk.
“We now have a 300-year catalog of earthquakes that has been well calibrated” to estimate their size and location, said Sykes. “We also now have a 34-year study of data culled from Lamont’s network of seismic instruments.”
“Earthquake risk is not the highest priority in New York City, nor is dog-poop free sidewalks,” Seeber recently commented. But, he added, both deserve appropriately rational responses.

New York Quake Overdue (The Sixth Seal Rev 6:12)

New York Earthquake Overdue

New York Earthquake Overdue

New York City could start shaking any minute now.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.
From Metro New York:
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.
“Today, with so many more buildings and people … we’d see billions in damage,” Armbruster said. “People would probably be killed.”

If the past is any indication, New York can be hit by an earthquake, claims John Armbruster, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory.

If the past is any indication, New York can be hit by an earthquake, claims John Armbruster, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory.
Based on historical precedent, Armbruster says the New York City metro area is susceptible to an earthquake of at least a magnitude of 5.0 once a century.
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.
There’s another fault line on Dyckman St and one in Dobbs Ferry in nearby Westchester County.
“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.”
“Considering population density and the condition of the region’s infrastructure and building stock, it is clear that even a moderate earthquake would have considerable consequences in terms of public safety and economic impact,” says the New York City Area Consortium for Earthquake Loss Mitigation on its website.
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.

Earth-shaking fire from the center of the earth.Will cause the towers around the New City to shake,Two great rocks for a long time will make war
There is recent scientific evidence from drill core sampling in Manhattan, that the southern peninsula is overlapped by several tectonic plates. Drill core sampling has been taken from regions south of Canal Street including the Trade Towers’ site. Of particular concern is that similar core samples have been found across the East River in Brooklyn. There are also multiple fault lines along Manhattan correlating with north-northwest and northwest trending neo-tectonic activity. And as recently as January and October of 2001, New York City has sustained earthquakes along these plates. For there are “two great rocks” or tectonic plates that shear across Manhattan in a northwestern pattern. And these plates “for a longtime will make war”, for they have been shearing against one other for millions of years. And on January 3 of 2010, when they makewar with each other one last time, the sixth seal shall be opened, and all will know that the end is near.
And then Arethusa will color a new river red.
Arethusa is a Greek mythological figure, a beautiful huntress and afollower of the goddess Artemis. And like Artemis, Arethusa would have nothing to do with me; rather she loved to run and hunt in the forest. But one day after an exhausting hunt, she came to a clear crystal stream and went in it to take a swim. She felt something from beneath her, and frightened she scampered out of the water. A voice came from the water, “Why are you leaving fair maiden?” She ran into the forest to escape, for the voice was from Alpheus, the god of the river. For he had fallen in love with her and became a human to give chase after her. Arethusa in exhaustion called out to Artemis for help, and the goddess hid her by changing her into a spring.But not into an ordinary spring, but an underground channel that traveled under the ocean from Greece to Sicily. But Alpheus being the god of the river, converted back into water and plunged downthe same channel after Arethusa. And thus Arethusa was captured by Artemis, and their waters would mingle together forever. And of great concern is that core samples found in train tunnels beneath the Hudson River are identical to those taken from southern Manhattan. Furthermore, several fault lines from the 2001 earthquakes were discovered in the Queen’s Tunnel Complex, NYC Water Tunnel #3. And a few years ago, a map of Manhattan drawn up in 1874 was discovered, showing a maze of underground waterways and lakes. For Manhattan was once a marshland and labyrinth of underground streams. Thus when the sixth seal is broken, the subways of the New City shall be flooded be Arethusa:the waters from the underground streams and the waters from the sea. And Arethusa shall be broken into two. And then Arethusa will color a new river red.
And then areth USA will color a new river red.
For Arethusa broken into two is areth USA. For areth (αρετη) is the Greek word for values. But the values of the USA are not based on morality, but on materialism and on wealth. Thus when the sixth seal is opened, Wall Street and our economy shall crash and “arethUSA”, the values of our economy shall fall “into the red.” “Then the kings of the earth and the great men and the commanders and the rich and the strong and every slave and free man hid themselves in the caves and among the rocks of the mountains; and they said to the mountains and to the rocks, ‘Fall on us and hide us from the presence of Him who sits on the throne, and from the wrath of the Lamb; for the great day of their wrath has come, and who is able to stand?’” (Revelation 6:15-17)

A small earthquake was reported on Tuesday morning in upstate New York.
The United States Geological Survey’s website says the small-shaker hit about 25km from Potsdam at 6:07 a.m. and was 6 km deep. It registered a tiny 2.1 on the Richter Scale.
Several residents reported the trembles and the reports were reviewed and confirmed by a seismologist. According to the same website the earthquake was measured and determined to be 6.0 kilometers below earth’s surface. The highest level on the Richter scale is 5.0.
There are no reports of injury.
According to a map on the USGS site, this is the 17th quake to hit the Empire State this year. The largest, a 2.2 magnitude, came on June 30th near Ticonderoga, NY.

NEW YORK CITY (PIX11) – For the last 43 years John Armbruster has been a seismologist with Columbia University’s Lamont Doherty Earth Observatory.  A veteran of what he describes as “a couple of dozen” quakes, he is interested in the seismic activity throughout the Pacific region in recent weeks.
However, does the amount of plate movements around the world in recent weeks as well as years to translate to New York City being more vulnerable, “These earthquakes are not communicating with each other, they are too far apart,” said Armbruster in an interview with PIX 11 News on Wednesday.
Nonetheless, Armbruster added that there are many faults around the area and a few in Manhattan, including on specific fault capable of producing a magnitude 6.0 earthquake, “The 125th street fault.”
What would a magnitude 6.0 earthquake inflict upon the city?
“I think there would be serious damage and casualties,” said Armbruster.  The reason?  Most of the buildings and infrastructure was not constructed  to withstand earthquakes.  This said, what does Armbruster think of the chances of a major earthquake catching New York City by surprise?
“We know that its unlikely because it hasn’t happened in the last 300 years but the earthquake that struck Fukushima Japan was the 1000 year earthquake and they weren’t ready for the that.

EARTHQUAKE HAZARD (Source: US Geological Survey)

NY hazard

New York State Geological Survey
Damaging earthquakes have occurred in New York and surely will again. The likelihood of a damaging earthquake in New York is small overall but the possibility is higher in the northern part of the state and in the New York City region. Significant earthquakes, both located in Rockaway and larger than magnitude 5, shook New York City in 1737 and 1884. The quakes were 147 years apart and the most recent was 122 year ago. It is likely that another earthquake of the same size will occur in that area in the next 25 to 50 years. A magnitude 5.8 earthquake in New York City would probably not cause great loss of life. However the damage to infrastructure – buildings, steam and gas lines, water mains, electric and fiber optic cable – could be extensive.
Earthquake Hazard Map of New York State
Acceleration of the ground during an earthquake is more important than total movement in causing structural damage. This map shows the two-percent probability of the occurrence of an earthquake that exceeds the acceleration of earth’s gravity by a certain percentage in the next fifty years.
If a person stands on a rug and the rug pulled slowly, the person will maintain balance and will not fall. But if the rug is jerked quickly, the person will topple. The same principle is true for building damage during an earthquake. Structural damage is caused more by the acceleration of the ground than by the distance the ground moves.
Earthquake hazard maps show the probability that the ground will move at a certain rate, measured as a percentage of earth’s gravity, during a particular time. Motion of one or two percent of gravity will rattle windows, doors, and dishes. Acceleration of ten to twenty percent of gravity will cause structural damage to buildings. It takes more than one hundred percent of gravity to throw objects into the air.

USGS: NYC Earthquake History Before The Sixth Seal


New York Earthquake History
Strong earthquakes in 1638, 1661, 1663, and 1732 in the St. Lawrence Valley and a shock near Newbury, Massachusetts, in 1727 were felt in New York before the first notable tremor centered within the State was recorded. On December 18, 1737, an earthquake near New York City threw down a number of chimneys (intensity VII). This shock was reported felt at Boston, Philadelphia, and at New Castle, Delaware.
Walls vibrated, bells rang, and objects fell from shelves (intensity VI) at Buffalo from a shock on October 23, 1857. Also, a man seated on a chair was reportedly thrown to the ground. At Lockport, rumbling noises were heard for a full minute. This shock was felt as far as Hamilton, Peterborough, and Port Hope, Ontario, Canada; Rochester, New York; and Erie and Warren, Pennsylvania. The total felt area covered approximately 46,000 square kilometers.
A rather severe earthquake centered in northeastern New York caused moderate damage along the St. Lawrence River and in the Lake Champlain area in 1877. Crockery was overturned, ceilings cracked, and chimneys were thrown down (intensity VII) from the November 4 tremor. At Saratoga Springs, buildings were shaken and a roaring sound was heard; at Auburn, windows were damaged. The earthquake was felt throughout a large part of New York and New England and eastern Canada, about 233,000 square kilometers.
On August 10, 1884, an earthquake caused large cracks in walls at Amityville and Jamaica (intensity VII). The shock was felt strongly at New York City. In addition, 30 towns from Hartford, Connecticut, to West Chester, Pennsylvania, reported fallen bricks and cracked plaster. The total felt area was estimated at 181,000 square kilometers.
A shock reported as severe, but with no damage noted (intensity VI), occurred in northeastern New York on May 27, 1897. It was felt over the greater portion of New York and parts of adjacent New England States and Quebec, Canada.
A very large area of the northeastern United States and eastern Canada, about 4,200,000 square kilometers, was shaken by a magnitude 7 earthquake on February 28, 1925 (March 1, universal time). A maximum intensity of VIII was reached in the epicentral region, near La Malbaie, Quebec, Canada. A large portion of New York State experienced intensity IV effects; lesser intensities were noted south of Albany.
Extensive damage occurred in the Attica area from a strong shock on August 12, 1929. Two hundred and fifty chimneys were thrown down, plaster was cracked or thrown down, and other building walls were noticeably damaged (intensity VIII). Many cemetery monuments fell or were twisted. Dishes fell from shelves, pictures and mirrors fell from walls, and clocks stopped. An increased flow at the Attica reservoir was noted for several days after the earthquake; a number of wells near the reservoir went dry. There was some damage at Batavia and other points at similar distances. A wall was cracked at Sayre, Pennsylvania. The earthquake was felt throughout most of New York and the New England states, northeastern Ohio, northern Pennsylvania, and southern Ontario, Canada; a total area of about 250,000 square kilometers. Strong aftershocks were felt at Attica on December 2 and 3; dishes fell from shelves and clocks stopped.
The opposite end of the State experienced similar damage from another shock less than 2 years later. On April 20, 1931, an earthquake centering near Lake George threw down about 20 chimneys at Warrensburg and twisted a church spire (intensity VII). A small landslide was reported on McCarthy Mountain. At Glen Falls, walls were cracked, dished broken, and clocks stopped. At Lake George, buildings swayed and store goods fell from shelves. At Luzerne, some Chimneys were damaged and windows broken. The shock was felt over 155,000 square kilometers, but with less intensity in the Catskills than at equal distances in other directions. This anomaly was also noted in the August 12, 1929, Attica earthquakes.
The magnitude 6 1/4 earthquake centered near Timiskaming, Quebec, Canada, on November 1, 1935, caused slight damaged at many points in New York. The damage was limited, in general, to plaster cracks, broken windows, and cracked chimneys. The shock was felt throughout New York, as far south as Washington, D.C., and as far west as Wisconsin. An earthquake centered near Lake Ossipee, New Hampshire on December 24, 1940, caused widespread, though slight, damage in the epicentral region, extending into Maine, Massachusetts, Rhode Island, and Vermont. Reports from Dannemora, New York, noted plaster and windows cracked and some dishes broken. The shock was felt over all of New York State.
On September 4, 1944, an earthquake centered about midway between Massena, New York, and Cornwall, Ontario, Canada, caused an estimated $2,000,000 damage in the two cities. The shock destroyed or damaged about 90 percent of the chimneys at Massena (intensity VIII), with similar effects at Cornwall. In addition, masonry, plumbing, and house foundations were damaged at Massena. Many structures were rendered unsage for occupancy until repaired. Press reports indicated a large number of wells in St. Lawrence County went dry, causing acute hardship. Brick masonry and concrete structures were damaged at Hogansburg; some ground cracking was also noted at nearby towns. This earthquake was felt over approximately 450,000 square kilometers in the United States, including all the New England States, Delaware, Maryland, New Jersey, Pennsylvania, and portions of Michigan and Ohio. A few points in Illinois, Indiana, Virginia, West Virginia, and Wisconsin also reported feeling the tremor.
A magnitude 4.7 disturbance on January 1, 1966, caused slight damage to chimneys and walls at Attica and Varysburg. Plaster fell at the Attica State Prison and the main smokestack was damaged (intensity VI). The total felt area was about 46,500 square kilometers.

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

History Says New York Is Earthquake Prone

Fault Lines In New York City

Fault Lines In New York City

If the past is any indication, New York can be hit by an earthquake, claims John Armbruster, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory.
Based on historical precedent, Armbruster says the New York City metro area is susceptible to an earthquake of at least a magnitude of 5.0 once a century.
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.
There’s another fault line on Dyckman St. and one in Dobbs Ferry in nearby Westchester County.
“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.”
“Considering population density and the condition of the region’s infrastructure and building stock, it is clear that even a moderate earthquake would have considerable consequences in terms of public safety and economic impact,” says the New York City Area Consortium for Earthquake Loss Mitigation on its website.
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)
