Wednesday, February 10, 2010 - We just had an earthquake. As soon as I heard the rattling (which woke me up just before 4:00 a.m.), and I opened the upstairs bathroom window and smelled no gas, I immediately said, "it was an earthquake." That's all for now folks. It's VERY early. bye, djb

I've updated this since my initial posting at around 4:30 a.m., because if someone comes back here later to read it, the first information I put on here is incorrect and I don't want to mislead anyone. Apparently, when the smart people got to work, they figured out where it really happened. Interesting that the depth is only 3 miles. Not that deep if you think about it. ~djb
