The 3.2-magnitude quake occurred at 8:22 a.m. seven miles northeast of Talmage, eight miles northeast of Ukiah and 11 miles west northwest of Upper Lake, according to the US Geological Survey.
It occurred at a depth of 4.8 miles, the agency reported.
The US Geological Survey received 39 shake reports from eight zip codes, including Witter Springs, Upper Lake, Lucerne, Lakeport, Ukiah, Redwood Valley and Pottery Valley.
One shake report came from nearly 900 miles away, from Sunburst, Montana, according to the survey data.
At 11:41 a.m. Friday, a 2.1-magnitude quake took place in about the same location near Talmage as the larger quake, only at a depth of 4.3 miles, the US Geological Survey reported. Two shake reports – one from Redwood Valley, one from Ukiah – were made on that second quake.
A 3.3-magnitude quake last September, which had its epicenter 2.8 miles deep and eight miles south southeast of Talmage, also was felt locally, as Lake County News has reported.
