The US Geological Survey (USGS) is reporting that a magnitude-5.8 earthquake struck about 100 miles off the coast of Northern California this morning, just hours after another quake rocked the Los Angeles area.

This morning’s quake hit at 8:39am local time at a depth of 3 miles and was centered under the ocean roughly 102 miles west of Capetown. Local media there reports to damage nor any injuries. On Twitter, residents said they felt it around Ferndale, a city located within Humboldt County.

Hours earlier, a magnitude 5.0 quake struck the Tabuco Canyon area at 2:09am local time. Located about 8.1 miles northeast of Tabuco Canyon and 15 miles south-southwest of Riverside, that quake was felt across Los Angeles, Riverside, and Orange Counties in southern California.
The Ring of Fire, of which California is a part of, has been especially active in recent days.
