There was a small 3.2 quake that occurred in the East Bay at 3:30 p.m. today, one kilometer Northeast of El Cerrito. We at SFist felt it in the Tendernob area (the first one we've felt in our eight years in SF), as did many Twitter users. It was quick and felt like a large truck driving by. There have been no immediate reports of injury or damage. Apparently, there was also a 5.2 earthquake in Southern Alaska early this morning and a small quake in Wales last night. Occurrences like these are always good reminders to prepare for the Big One.
