The United States Geological Survey said the epicenter of the quake, which occurred at 1:26 p.m., was 12 miles northeast of Upper Lake, 13 miles southeast of Lake Pillsbury and 13 miles north northeast of Nice.
The quake was recorded at a depth of about eight miles, the survey reported.
Within about a half hour of the quake the US Geological Survey had received nearly a dozen shake reports from Upper Lake, Clearlake, Kelseyville, Nice and Stonyford.
Liela Hopper-Jones, who lives in Nice, told Lake County News that the earthquake was just a “quick loud boom,” like something was hitting her house.
