Earthquake Strikes East Coast; Epicenter Near Richmond, Va., U.S. Geological Survey Says: An earthquake sent tremors from the nation’s capital to New York City Tuesday afternoon, the result of what officials said was a 5.8 magnitude earthquake based in Virginia. There were no immediate reports of damage.
It is not clear how far the earthquake spread, but tremors were felt throughout New York City office buildings and as far north as Concord, N.H.

Strongest quake since ’44 jars East Coast: Tens of millions of people from Georgia to Canada were jolted Tuesday by the strongest earthquake to strike the East Coast since World War II. Three weeks before the 10th anniversary of Sept. 11, office workers poured out of New York skyscrapers and the Pentagon, relieved it was nothing more sinister than an act of nature….. – AP, 8-23-11

“For many people this was a stressful afternoon, but so far we’ve been lucky to avoid any major harm.” — Mayor Bloomberg

Magnitude-5.8 Earthquake Strikes National Capital Area:
U.S. Department of the Interior, U.S. Geological Survey
A magnitude 5.8 earthquake struck the National Capital Area on Tuesday, August 23, at 1:51p.m. (EDT), causing moderate shaking and potentially significant damage, and was felt throughout Northern Virginia and neighboring areas. No casualties are expected.
The earthquake occurred near Louisa and Mineral, Va., approximately 100 miles southwest of Washington, DC. It was a shallow earthquake, and shaking was recorded all along the Appalachians, from Georgia to New England. There have been several aftershocks.
The earthquake occurred in the Central Virginia Seismic Zone, which has produced earthquakes in the past. The most notable was an earthquake that occurred in 1875 that scientists believe was about a magnitude 4.5.
This earthquake is almost as strong as the strongest recorded earthquake in Virginia, a magnitude 5.9, which occurred in May 1897 in Giles County, Va. The strongest recorded earthquake to strike the East Coast was the 1886 Charleston, S.C., earthquake, which was about a magnitude 7.3.
Those who felt the earthquake can go online and report their observations on the USGS Did You Feel It? website. Over 10,000 reports of felt shaking have already been received from more than 3400 zip codes all over the eastern United States.
The earthquake was felt so widely because it was a shallow earthquake, and geologic conditions in the eastern U.S. allow the effects of earthquakes to propagate and spread much more efficiently than in the western United States.
Western rock is relatively young, which means it absorbs a lot of the shaking caused by earthquakes. Thus, western earthquakes result in intense shaking close to the epicenter, but fade more quickly the farther the earthquakes travel.
In the eastern United States, on the other hand, the rock is far older, and so earthquakes can have a much larger and more widespread impact. Earthquake energy can therefore spread farther and have a greater impact…..
