Aftershocks continue to shake Virginia

As if the East Coast’s magnitude 5.8 earthquake wasn’t distressing enough, Virginia’s got a whole lotta shaking going on.

A 4.5 aftershock struck near Richmond early Thursday, the U.S. Geological Survey said on its website. The temblor, which hit at 1:07 a.m. Eastern time, was centered in the same area as Tuesday’s earthquake. The epicenter was about 36 miles northwest of Richmond and about 80 miles southwest of Washington.

And that’s not the only aftershock: The Geological Survey lists four others since Tuesday’s 1:51 p.m. quake: 3.4, 4.2, 2.8 and 2.2.

But in the greater scheme of things, that’s a remarkably low number of aftershocks, geophysicist Amy Vaughan of the National Earthquake Information Center in Colorado told the Associated Press.

Thursday’s earthquake was at a depth of 3 miles below ground — about the same as Tuesday’s quake.

A Geological Survey map of the shake zone estimated that the perceived shaking at the epicenter was moderate, with potential damage very light. http://earthquake.usgs.gov/earthquakes/shakemap/global/shake/c0005jg1/ In contrast, Tuesday’s quake was classified as having very strong shaking.
