596. Another one. Just now.

It lasted longer, like 5 seconds (the first one lasted about 3), with about the same to slightly less intensity. It started out jolty, but then settled into the rolling, swaying kind of earthquake.

Give me a White Christmas any day. Rockin' Around the Christmas Tree can be quite dizzying and alarming.

Wow. This site is GOOD. Real time earthquake info! How do they do it?
