LOS ANGELES (AP) – Ridgecrest, California, Mayor Peggy Breeden says firefighters are working to put out five fires in the area following an earthquake but that she didn’t know if any injuries have been reported.  Breeden tells CNN utility workers are assessing broken gas lines and turning off gas where necessary.  Breeden says the local senior center was holding a Fourth of July event when the quake hit. She says everyone made it out shaken up but without injuries.  The 6.4 magnitude quake struck at 10:33 a.m. Thursday in the Mojave Desert, about 150 miles (240 kilometers) northeast of Los Angeles, near Ridgecrest. It is the strongest quake to hit the region in 20 years.  Seismologist Lucy Jones says a series of aftershocks were occurring and that at least one of them was a 4.3 magnitude temblor. She expects more throughout the day.  Get the latest at the top and bottom of the hour on FM News 101 and kxl.com
