Thought about the T-rex scene from Jurassic Park and went back to work. Just felt earthquake like thing at my desk in NYC anyone else? Floor and chair moved earthquake eastcoastnotusedtothis helpfromleftcoast. Did you feel that? There are no reports of injuries or damage in NYC at this time. Won-Young Kim is a senior research scientist at Columbia University's Lamont-Doherty Earth Observatory, which monitors and records data on earthquakes that occur in the northeast. Kim says it's not clear who feels smaller earthquakes, as evident by a magnitude 0.
Our system was unable to detect that tiny earthquake automatically," Kim said. Kim says some parts of the city will feel magnitude 1 or 2 earthquakes even if the seismic activity does not result in any damage.
You have to go back to before the 20th Century, however, to find the last significant earthquake that hit the city. According to Lamont-Doherty researchers, magnitude 5. In newspaper accounts, New Yorkers described chimneys falling down and feeling the ground shake underneath them.
According to Kim, the quake was felt in areas in or close to the city, such as the Rockaways and Sandy Hook, New Jersey. But it was felt even as far away as Virginia and Maine. From to , there were known earthquakes in a 15,square-mile area around New York City, researchers at Lamont-Doherty said in a study. Smaller earthquakes are not to be ignored. Lamont-Doherty researchers say frequent small quakes occur in predictable ratios to larger ones and thus can be used — along with the fault lengths, detected tremors and calculations of how stress builds in the crust — to create a rough time scale.
Researchers say New York City is susceptible to at least a magnitude 5 earthquake once every years, a 6 about every years, and 7 about every 3, years. It's been years since New York was last hit by at least a magnitude 5. When it happens next, researchers say it won't be much like Before , earthquake risks were not taken into consideration for the city's building code.
Thus, Lamont-Doherty says many older buildings, such as unenforced three- to six-story buildings, could suffer major damage or crumble. Louis, Mo. This assessment is Louis has experienced minor earthquake damage at least 12 times in the past years. Because of this history and its proximity to known active earthquake zones, the St. Louis Area Earthquake Hazards Mapping Project will produce digital maps that show variability of earthquake hazards in the St.
Louis area. The maps will be available free via Although geographically distant, the State of Gujarat in India bears many geological similarities to the Mississippi Valley in the Central United States.
The Mississippi Valley contains the New Madrid seismic zone that, during the winter of , produced the three largest historical earthquakes ever in the continental United States and The map shows the locations of 1, known earthquakes of magnitude 3.
Earthquakes are unsettling, destructive, and often tragic to the communities they affect. The USGS works diligently to help keep people safer by providing them and their emergency responders the science needed to respond to ongoing hazards.
Why was an earthquake in Virginia felt at more than twice the distance than a similar-sized earthquake in California? The answer is one that many people may not realize.
Earthquakes east of the Rocky Mountains can cause noticeable ground shaking at much farther distances than comparably-sized earthquakes in the West.
Computer simulations of earthquake shaking, replicating the quakes that occurred in in the New Madrid seismic zone NMSZ , indicate that future large earthquakes there would produce major, prolonged ground shaking.
Imagine the Delaware River abruptly rising toward Philadelphia in a tsunami-like wave of water. Scientists now propose that this might not be a hypothetical scenario.
A newly published paper concludes that a modest one-foot tsunami-like event on the East Coast was generated in the past by a large offshore earthquake. What if you knew that a magnitude 7. Scientists from the U.
A minor earthquake, preliminary magnitude 3. The epicenter was about 95 miles north northwest of Albany. The USGS has received no reports of damage at this time. A timeline of earthquakes in the New Madrid Seismic Zone top differs significantly from a typical aftershock sequence bottom. A new study shows that earthquakes occurring today in the region are not aftershocks of the earthquakes.
Rather, they are evidence that stress is continuing to accumulate. The Washington Monument, made of marble, granite, and bluestone gneiss, commemorates the first president of the United States. The monument was damaged in the Virginia earthquake, but has since been repaired.
Mike Blanpied discusses whether a similar event could occur again in the region in the near future, and in an earthquake, what you can do to stay stay safe. Blanpied discusses how scientists are using the August 23 earthquake to inform estimates of the region's seismic hazard. The magnitude 5. It caused extensive damage in central Virginia and was likely felt by more people than any other earthquake in U.
This is part of a study documenting landslides triggered from the magnitude 5. Green grass beneath the rock fragments indicates that the rock fall is fresh and probably was triggered by the earthquake. Photo of chimney damage at a house in Louisa County, Virginia.
This was a result from a magnitude 5. A magnitude 5. Damage to a house in Louisa County, Virginia, after a magnitude 5. Skip to main content. Search Search. Natural Hazards. Apply Filter. What are the Great ShakeOut earthquake drills? ShakeOut GIF showing what to do in an earthquake if you are near a sturdy desk or table. Public domain. The Great ShakeOut earthquake drills are based on scenario earthquakes that could effect the area if they were to actually take place.
Great ShakeOut Earthquake Drills are an What is the "Triangle of Life" and is it legitimate? The "Triangle of Life" is a misguided idea about the best location a person should try to occupy during an earthquake.
The largest earthquake centered in New York took place on September 5, With a magnitude of 5. Similar kinds of damage were reported at Cornwall, Ontario. This earthquake was felt from eastern Maine to central Michigan and to Maryland. An earthquake of magnitude 5. In Attica many chimneys were thrown down, brick walls were cracked, and the aisles of stores were littered with goods thrown from the shelves.
This earthquake was felt as far east as central New Hampshire and as far west as Cleveland, Ohio. Subsequent to this earthquake, shakes that were notable in the Attica area but caused little or no damage took place on August 15, , July 16, and January 1, The New York City area has experienced two damaging local earthquakes during its history. The first, about p. A local magnitude of 5.
On the other hand, the second was a well-studied earthquake that occurred on August 10,
