[Update] Wapo reports that this might just be "foreshock," and more possibly to come:

Minutes after the quake, the director of the U.S. Geological Survey, 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 worse is yet to come.”

[Update] More on the nuclear power plants from WSJ and CNN.

CNN:

Tuesday's Virginia earthquake triggered the shutdown of a nearby nuclear power plant and alerts at nine others across the East Coast, U.S. authorities reported.

Dominion Virginia Power said both reactors at its North Anna plant, less than 20 miles from the epicenter of the magnitude-5.9 quake, shut down after the first tremors. Amanda Reidelbach, an emergency management spokeswoman for Louisa County, said the plant venting steam, but there was no release of radioactive material.

David Heacock, the utility's chief nuclear officer, said the plant was operating on emergency power and the units were safely deactivated.

"The plants are designed for this kind of a seismic event," Heacock said. "There is no apparent damage to anything at the plant right now."


WSJ:

The North Anna Power Station, which has two nuclear reactors, is now using four diesel generators to maintain cooling operations. The plant automatically shut down in the wake of the earthquake.

"As far as we know, everything is safe," said Nuclear Regulatory Commission spokesman David McIntyre.

Nine nuclear plants have declared "unusual events" today, which is the lowest of four emergency situations, the NRC said.

The plants are located in Virginia, Maryland, Pennsylvania and New Jersey.

Side Note: I didn't see this amount of attention given to the earthquake in Colorado yesterday.

The largest natural earthquake in Colorado in more than a century struck Monday night in the state’s southeast corner, but there had been no reports of damage or injuries.
