COBB, Calif. – A Sunday night quake with its epicenter on Cobb Mountain received hundreds of shake reports from around Northern California.

The quake, which occurred at 8:47 p.m., initially was reported as being 4.4 in magnitude, but was later dialed back slightly to 4.3 after it was reviewed by a seismologist, according to a U.S. Geological Survey report.

Centered three miles east of The Geysers geothermal steamfield, three miles south southwest of Cobb and three miles west northwest of Anderson Springs, the earthquake occurred at a depth of two-tenths of a mile, the U.S. Geological Survey said.

By 1 a.m. Sunday the U.S. Geological Survey had received approximately 336 shake reports from 51 zip codes around California.

Reports came in from around Lake County, with many more submitted from residents in Napa and Sonoma counties, communities around the Bay Area and even from Turlock, located more than 200 miles away in the Central Valley.

A 2.6-magnitude temblor occurred eight minutes after the bigger quake, centered two miles west northwest of Anderson Springs at the depth of about a mile, the survey reported.

According to Lake County News records, the last quake measuring 4.0 or above in The Geysers area occurred a year ago this month, when a 4.5-magnitude quake was recorded one mile from The Geysers.
