Southern California town declares emergency over quake swarm
LOS ANGELES | Thu Aug 30, 2012 6:04am IST
Aug 29 (Reuters) - The southern California town of Brawley has taken the unusual step of declaring a state of emergency after a swarm of earthquakes rattled nearly 20 mobile homes off their blocks and forced a slaughterhouse to close, the mayor said on Wednesday.
It is uncommon for quake-hardy California cities to declare emergencies due to tremors, but Brawley mayor George Nava said the earthquake swarm is a unique case because it has lasted for days and caused millions of dollars in damage.
The cluster of relatively small quakes, which are caused by water and other fluids moving around in the Earth's crust, began on Saturday evening and climaxed the next day with a 5.5 temblor, according to the U.S. Geological Survey.
The tremors were continuing on Wednesday and geologists say there have been hundreds in total.
Nava said leaders in Brawley, a city of 25,000 residents south of the state's inland Salton Sea and 170 miles (275 km) southeast of Los Angeles, declared a local emergency late on Tuesday. Officials with surrounding Imperial County made a similar declaration on Wednesday.
Nineteen mobile homes were knocked off their blocks and their residents forced out, Nava said. The auditorium at Brawley Union High School has been damaged and closed off, and the National Beef slaughter plant in Brawley has been temporarily shut down due to damage, he said.
