I’m up in Ottawa Canada and my wife and I felt it….gentle swaying back and forth.
This area still rebounding from the last ice age.

We need to start a pool – who will be the first news agency to carry a story attempting to blame this on /associate this with global warming?

Felt it here in Norfolk, VA, but that’s a lot closer than others.
Nate, my mother was from Sayer, PA. Spent a lot of time up there on vacation when I was a kid. Really liked it.

Yea, people in San Fran would freak out if they suddenly got hit with 2 feet of snow and 15 degree temps. To each his own disaster.

The epicenter was right below the North Anna Nuclear station. I have facebook messaged two friends who work there to see if the plants tripped. Cell phones are overwhelmed here in Richmond. My son works in DC and they just now got cleared to go back in their building

This quake was very close to Monticello, Thomas Jefferson’s home in VA. Was there any damage to his home or the out-buildings?

Fox news just reported that the nuclear units were taken offline. Did not say whether that was manual or automatic due to seismic sensors

Can’t blame it on Global Warming… but could be blamed on melting ice caps…. all the weight of all that ice flowing off the arctic and antarctic as water could cause the earth’s mantle to “rebound” in its slow and deliberate way …. but we may need to see some more weight redistribution before that becomes truly significant.
