At the base of the San Andreas Fault, where 42 small quakes struck over the weekend, a moderate 4.8 magnitude quake occurred this morning around 4:55 a.m., the LA Times is now reporting. It was followed by 23 aftershocks including a 3.1 shaker. "The only interesting thing about this one is that it occurred at the end of the San Andreas fault," said Kate Hutton, a seismologist at Caltech, to the Times. "Bombay Beach is considered the southern end of the San Andreas fault. The last swarm of earthquakes similar to this was in 2001. We're watching it closely. We'll be analyzing everything."




I'm not from California, so I don't know for sure, but isn't it common to have that many aftershocks for an earthquake of that magnitude?
4.8 is really not that big at all. If it happened right now in LA, people would be definitely talking about it, but if you remember the one from this summer, that was 5.4, meaning it was 600 times stronger than the 4.8 (I think I did my math right, LA Map Nerd, where are you?!?!).
