Earthquakes in Arizona???

Yes, my friends it is true. There was an earthquake close enough to Arizona to knock out power in Yuma. You can read about it in the newspaper from Yuma. The 7.2 earthquake was centered about 42 miles south of Calexico in Mexico, but it was strong enough in Yuma to shake things off the shelves in the supermarkets. You can also read about it on the USGS Earthquake site.

Here is the technical info on the quake again from the USGS:
