It felt like a vehicle struck my house. Not very exciting or scary in and of itself but, I guess we've been getting more and more the past 2 years, and that troubles me a little.
Unofficially it was a 4.2 off the coast. The nearest observatory I can find that registered it was in Boston at 5:48PM EST.

Click short range and back one day to see it clearly if you want to.
I'm just worried the increased frequency of these smaller ones is a sign of a coming "real" earthquake, since we haven't had one in hundreds of years. (1755 we had a 6.0 estimated)
Just figured I'd toss this out there. I've never lived anywhere that earthquakes were common enough to pass up commenting on. I've got a friend who moved from here to Japan and he feels this level of earthquake regularly.
