Emergency crews in Southern California are responding to at least 24 medical and fire incidents in the wake of a 6.4 magnitude earthquake that struck near Ridgecrest, California.
There have been no reports of injuries in the Los Angeles area, which is about 240-kilometres southwest of Ridgecrest -- home to around 28-thousand people.
People from Las Vegas to the Pacific Coast reported feeling the quake.
