California Earthquake Swarm

In the past few days, the Salton Sea area of southern California has been experiencing an earthquake swarm - with a few quakes as large as the mid-4's on the Richter Scale. With this swarm comes an increased probability of a large quake on that section of the San Andreas fault. A large quake in this area could effect Yuma and western Arizona - especially if it ruptured from north to south. The Arizona Geology blog has a good write-up about it.

In other geology news, there is a huge volcanic eruption going on at Redoubt in Alaska. There are good updates at the Eruptions blog and the AVO.
