magnitude was downgraded to 3.6
It looks like it’s normally a very quiet area, seismically.
That was interesting.... Felt it a ways west of DC.
It’s baffling when you aren’t used to them.... Does not compute! =D
woke us up in Clarksburg. Felt like an explosion.
Founding Fathers rolling in their grave.
Drat, couldn’t feel it at the bus stop in Front Royal. Had to experience it via email from someone further east.
Amen. Or, earth preparing to split open and swallow him up.
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.”
Thank goodness,here come the Haitian relief workers!
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.
Daggone! That’s near my office!
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.
Thanks. Mrs. Valentine and I felt it in Silver Spring and wondered what the? Now we know.
Did anyone survive?
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.
