Maybe you felt them. Two earthquakes hit Southern California early Thursday morning. A magnitude 4.2 quake happened at 4:29 a.m. It was centered in the San Fernando Valley, about a mile north of Pacoima, and was felt in much of Los Angeles and Ventura Counties.
It was followed by a magnitude 3.3 quake just a few minutes later, at 4:38 a.m.
There are no reports of damage or injuries, but they shook hundreds of thousands of people awake. Many people described the first quake as a jolt which lasted a few seconds.
