It looks like it’s normally a very quiet area, seismically.

Drat, couldn’t feel it at the bus stop in Front Royal. Had to experience it via email from someone further east.

Bush will be blamed. Obama will take credit for no damage.

Building shook a little in Virginia. I thought, “This couldn’t be an earthquake; they don’t have them here.”

Being a mile NNE of Gaithersburg puts it around Montgomery Airpark.

Here in Olney we heard it. For about 5 seconds or more it sounded like a truck going over rumble strips without the depressed sections.

I’ve only felt one earthquake, and it was very minor, but it took me by surprise because we usually don’t get them. All of a sudden, I heard this sound which sounded like a low rumble of thunder, but unlike thunder, it was longer. Then, everything began to vibrate for maybe 30 seconds or so. The epicenter was nearly a state and a half away. I was a little unsure about what happened until they said on the morning news that it was an earthquake.

I’m in N.E. Columbia. Woke me up too. I lived in California for 14 years, so I know an earthquake when I feel one.

Rapid, small side-to-side movement, like a heavy vibration.

Seemed to last 5 to 10 seconds.

Traffic on 66 eastbound. Looks like all zombies, so I would say no.
