4.0, 3.0 quakes hit The Geysers

THE GEYSERS – A string of 32 small earthquakes – capped by two larger quakes, one measuring 4.0 and a second 3.0 in magnitude – shook the area of The Geysers, Anderson Springs and Cobb Saturday.

The US Geological Survey reported that 4.0 quake occurred at 12:50 p.m. It was centered one mile northeast of The Geysers and four miles west southwest from Cobb.

There were 24 reports made to the US Geological Survey from individuals who felt the quake from Kelseyville all the way to San Francisco. Ten people in Middletown reported feeling the quake.

At approximately 12:57 p.m., a 3.0 quake occurred three miles north of The Geysers and four miles west of Cobb, according to the US Geological Survey.

There were nine reports from people who felt that quake, five of them in Middletown, one in Lower Lake and other reports coming from Healdsburg, Petaluma and even San Francisco, according to the US Geological Survey.

The last time an earthquake over 3.0 in magnitude was felt in Lake County was Sept. 17, when a 3.5 quake was recorded by the US Geological Survey nine miles northeast of Hidden Valley Lake, as Lake County News previously reported.

A quake of 4.0 magnitude hasn't occurred in the county since a 4.4 magnitude quake hit The Geysers area on April 24, based on US Geological Survey records.
