Mexico Earthquake Zone Linked to California Faults

This article talks about a 7.2 earthquake that jolted northern Mexico and Southern Califorinia April 4, 2010. Scientist say it was the first big earthquake on the particular fault since 1892. Mark Benthein says that its all basicly one fault zone, the plate boundary between the Pacific plate and the North American plate. It says that Southern California and northern Mexico are a whole series of blocks sliding past each other.

This is an interesting article. I find it amazing that a fault in California can cause the same fault line in Mexico to do the same thing. It has been a long time since the last earthquake.
