Hi Teri, I didn't realize Virginia had earthquakes. I got an earthquake alert on my phone, the other day. I didn't feel it, but both cats came out from their hiding places to check things out.

Hi Janice...there are at least three seismic zones in Virginia. The “big one” was in 2011 and was a 5.8, with the epicenter in central Virginia. It was felt up and down the entire East Coast, making it the most felt earthquake in US history. You can read more about it here, if you like geeking out about seismic activity:

The article has several charts that are quite interesting.

The smaller one might have been a 2.2 a month earlier (although I thought both occurred in September...go figure) with its epicenter in Maryland. That would have been an entirely different fault.
