Must have been something else. No mention of anything happening on the local news.
It was a big thump sound and shook the whole house pretty good. That's the way most of do when we have one. "If" we did, I'd guess it to be about a 2.5 where Im at...nothing to get all excited about, might crack the brick work or something but that's about it.
We had a 3.2 about 20 years ago. It was a loud BOOM and shook things a bit. I thought it was a sonic BOOM. This shake was similar is why I thought it might be a small quake.
