Earthquake shakes Southern California’s San Fernando Valley

A magnitude 4.2 earthquake shook Southern California’s San Fernando Valley just before 4:30 a.m. Thursday, the United States Geological Survey said.

The light quake which felt like a jolt, a pause, and then a bit more rocking, was centered near Pacoima.

Pacoima is about 23 miles northwest of downtown Los Angeles.

The USGS initially reported a magnitude 4.5 tremor, but has since downgraded it.
