Click Until the magnitude 5.8 earthquake in 2011, the largest earthquake to occur in Virginia was the 1897 magnitude 5.8 Giles County earthquake. felt. This equates to an average of one earthquake occurring every The USGS found that the farthest landslide from the 2011 Virginia earthquake was 150 miles (240 km) from the epicenter. Estimated magnitude: 5.8-5.9. People in certain areas of Pennsylvania, however, did not feel the earthquake at all despite being relatively close to the epicenter. website. month with two felt each year. The temblor was the strongest east … Earthquakes in Virginia listed by magnitude and date. The first four (of magnitude 2.8, 2.2, 4.2 and 3.4) occurred within 12 hours of the main shock. Previous studies of worldwide earthquakes indicated that landslides occurred no farther than 36 miles (58 km) from the epicenter of a magnitude 5.8 earthquake. Click here for a discussion on the observed effects of this event. USGS Director Marcia McNutt said, "Scientists are confirming with empirical data what more than 50 million people in the eastern U.S. experienced firsthand: this was one powerful earthquake. The epicenter was determined with 30 km by retropropagating 2 min of EMSC website traffic without using any seismic data. Chapman* (2014). the California coast are on a boundary between two plates, they have The earthquake was the strongest recorded east of the Rocky Mountains since 1944 and the strongest ever recorded in central Virginia’s seismic zone.
USGS scientists found that the Virginia earthquake caused landslides at distances four times farther—and over an area 20 times larger—than previous research had shown. The study suggested that the added information about East Coast earthquakes may prompt a revision of equations that predict ground shaking. The Mineral earthquake had a very prolific aftershock sequence, which is still being studied. This earthquake is the third largest in the eastern US in the last 200 years and was felt in twelve states. ... Latest earthquakes in Virginia, USA Earthquake list: past 30 days. February 5, 1898. For example, Twitter users in such cities as New York City and Boston reported reading tweets about the earthquake from users in Washington, D.C., or Richmond, Virginia, 15 to 30 seconds before feeling the quake itself.The Euro-Mediterranean Seismological Centre (EMSC) website, one of the top global earthquake information website experienced a massive and immediate traffic surge caused by the convergence of eyewitnesses looking for information about the shaking. Scientists plotted the landslide locations that were farthest out and then calculated the area enclosed by those landslides. East of the Soon after the earthquake, the U.S. A huge increase of cell-phone calls immediately after the event congested the The epicenter of the earthquake was in Multiple reactor sensors at the Two, spare replacement panels of the Vietnam Veterans memorial that were stored at Quantico Marine Base were knocked down and shattered.Trembling was felt in buildings in Tremors were felt to varying degrees throughout The earthquake was felt throughout much of the six Tremors from the earthquake were felt as far north as The earthquake was felt in several southern states as far from the epicenter as Tremors from the earthquake were also felt in eastern Canada, mostly in According to Facebook, the word "earthquake" appeared in the status updates of 3 million users within four minutes of the quake.
The earthquake occurred in the The earthquake's epicenter and most of the aftershocks lie between the surface traces of two structures, the Spotsylvania Fault, a southeast dipping zone of high ductile strain, and the Chopawamsic Fault, a After the earthquake, several websites speculated about whether Numerous aftershocks occurred after the main tremor. center of the North American plate (Figure 1a). Several aftershocks, ranging up to 4.5 Mw in magnitude, occurred after the main tremor. Their hit times proved to mimic the seismic wave propagation generated by the earthquake. Calibrating the distance over which landslides occur may also help us reach back into the geologic record to look for evidence of past major earthquakes from the Virginia seismic zone." It was an intraplate earthquake with a maximum perceived intensity of VII (Very strong) on the Mercalli intensity scale. Previous studies of worldwide earthquakes indicated that landslides occurred no farther than 36 miles (58 km) from the epicenter of a magnitude 5.8 earthquake. The quake was felt across more than a dozen U.S. states and in several Canadian provinces, and was felt by more people than any other quake in U.S. history.The earthquake prompted research that revealed that the farthest landslide from the epicenter was 150 miles (240 km), by far the greatest landslide distance recorded from any other earthquake of similar magnitude. The observed landslides from the Virginia earthquake enclose an area of about 33,400 kmIt is estimated that approximately one-third of the U.S. population might have felt the earthquake, more than any other earthquake in U.S. history.
