BAY AREA, CA — A magnitude 5.6 earthquake struck Wednesday morning, sending a sharp jolt through the North Bay, rattling homes across Sonoma County, and prompting residents throughout Northern California to report shaking.

The quake was felt across the Bay Area, with some residents reporting movement as far away as Lake Tahoe.

According to the U.S. Geological Survey, the earthquake struck at 8:10 a.m. at a depth of approximately 5 miles. The epicenter was located about 7 miles north of Redwood Valley in Mendocino County.

County officials are still assessing potential damages.

Residents across the North Bay described swaying light fixtures, shaking windows, rattling dishes, and rolling motion as the earthquake moved through the region.

In Upper Lake and Kelseyville, residents said the quake rattled objects off of shelves, leaving shattered glass but no injuries.

Even in areas farther from the epicenter, like Healdsburg— an hour south on HWY 101 — the earthquake jolted homes in a jarring back and forth motion.

The quake and emergency alerts jolted awake sleepers.

"The alert is shocking woke me up so quickly and frightened that I think the adrenaline in my body overrode, any feeling of shaking and nothing in my room on the shelves appeared to move," wrote a woman from Healdsburg on Facebook.

In Clearlake, a man wrote that the earthquake "felt like the one in Loma Prieta quake in the Bay Area."

"Came in two waves here in Kelseyville. Pool water splashed out in waves and lots of creaking & shaking," another woman wrote.

Residents in nearby Napa and Marin counties also got warnings as well but reported feeling little shaking.
