This evening at 7:33 pm a light quake, M4.3, rumbled (very) southern California. The earthquake’s origin was located 4 miles (7 km) north-northwest from Ocotillo Wells. It was felt extensively — though weakly and lightly — in San Diego, Imperial and Riverside counties. If you look below at the Weekly Report you’ll see we’ve had a number of foreshocks in that area.
