Is this California, or Massachusetts?

I woke up at around 1:20 this morning because my cell phone fell off my bedside table. I didn't think much of it, since I had only been asleep for about an hour (having stayed up for the SOX game). I picked it up, and went back to bed.

I woke up the next morning to reports of an earthquake that hit Littleton Common. It was a 2.5 on the Richter Scale.

Students were telling stories all day about how their pets woke them up. I don't remember thinking earthquake this morning, but apparently it was felt across the area.
