New quake: The epicentre of this latest earthquake, measuring 3.4, was just four miles from Mineral, where last week's 5.8 quake started

Central Virginia has been shaken by another aftershock from last week's earthquake that rattled the East Coast.

The U.S. Geological Survey reported a 3.4 magnitude aftershock at 5.09am this morning.

The epicentre was four miles south-southeast of Mineral, the town that was the epicentre of last Tuesday's 5.8-magnitude earthquake.

More than 20 aftershocks ranging from 4.5 to 1.8 have followed the earthquake.

US: Earthquake may have exceeded Virginia nuke plant's safeguards

The earthquake that prompted the shutdown of a Virginia nuclear power plant last week may have been more severe than the plant's reactors were designed to withstand, federal regulators said.

The revelation is likely to put increased pressure on the Nuclear Regulatory Commission (NRC) to quickly implement a series of safety recommendations intended in part to protect plants from major natural disasters like earthquakes.

NRC said Monday that its preliminary analysis indicates that the ground motion caused by the magnitude-5.8 earthquake near the North Anna Power Station in Louisa County, Va., exceeded the maximum level the two reactors at the plant were built to handle.

But the commission noted in a statement Monday that "data is still being collected and analyzed to determine the precise level of shaking that was experienced at key locations within the North Anna facility."

US: Virginia Earthquake 2011: USGS Warns it May be a Foreshock

Wed, 24 Aug 2011 14:52 UTC

A 5.8 magnitude earthquake centered in Virginia rocked the Mid-Atlantic, sending shockwaves up and down the East Coast through Washington D.C., New York City, and up all the way to Concord, N.H., and Toronto, Canada.

According to the United States Geological Survey (USGS), the quake happened at 1:51 p.m. at a depth of 3.7 miles. The quake was centered 27 miles east of Charlottesville, Va., near the town of Mineral in Louisa County, Va.

The movement lasted for no more than 30 seconds.

Minutes after the quake, the director of the USGS, Marcia McNutt -- who watched objects falling from the shelves in her office -- cautioned that the shaking might not be over.

"What the concern is, of course, is that this is a foreshock. If it's a foreshock, then the worst is yet to come," McNutt told The Washington Post.
