At around 10:50 p.m. tonight, there was a second earthquake almost in the exact same spot on the Hayward Fault (3 miles ESE of Berkeley) and at almost the same intensity (3.7) as the quake two days ago. We didn't feel the one on Wednesday ourselves (we were out drinking, which might have had something to do with it) but the one tonight definitely rattled our windows, and went on for a few seconds longer than we're used to. You can report your quake experience to the US Geological Survey here.

We always appreciate it when the earthquakes happen near the 11 p.m. news half-hour, so we can get our updated information without it interrupting other TV shows. It was a busy day at ABC 7, where word on the quake interrupted a story about an exchange of fire between a police officer and a suspect in the Sunset (suspect is dead, police officer is critically injured in the head -- no link yet) the story about the SF Zoo trainer getting mauled by the tiger this afternoon.

Interestingly, both of those stories were reported by the same reporter, Carlos Roman (?)(presumably the only guy in the office for the holidays), and poor Carlos was probably standing outside SF General waiting to go live when the earthquake hit too. He looked kind of unnerved -- but hey, that man is a news magnet!
