Earthquake swarm puts California town on edgeAugust 27, 2012 in Earth / Earth Sciences
(AP)—Aftershocks continue to shake the Southern California desert a day after moderate earthquakes knocked farming town trailer homes off foundations and shattered windows in a swarm that scientists say could last for days.
There are no injuries.
The largest quake centered near Brawley was at a magnitude-5.5 at 1:57 p.m. Sunday and it was widely felt from San Diego to Arizona. About 90 minutes earlier, a magnitude-5.3 quake shook the region.
By dawn Monday, the U.S. Geological Survey website shows there have been dozens of aftershocks in Imperial County, the largest a magniutude-4.9 at 9:41 p.m. Sunday. There was also a 3.0 at 12:32 a.m. Monday.
There was cosmetic damage to several 1930s buildings in downtown Brawley and 20 mobile homes were knocked off their foundations and deemed uninhabitable.
