A 5.6-magnitude earthquake struck in Mendocino County on Wednesday morning, according to the U.S. Geological Survey.

The quake was reported at 8:10 a.m. about 7 miles north of Redwood Valley, USGS officials said.

The earthquake was about 5 miles in depth and there was a 2.5-magnitude aftershock several minutes later.

Earthquake alerts were sent to people as far away as the Bay Area because of the shaking, which lasted about 30 seconds. The quake was strong enough to cause pictures and objects to fall off walls and shelves in Redwood Valley.
