Another shaker hits The Geysers, results in property damage

THE GEYSERS – A 3.0-magnitude earthquake that occurred early Wednesday left at least one home in Anderson Springs with property damage.

The US Geological Survey reported that the earthquake occurred at 5:42 a.m. at a depth of 2.4 miles.

The quake's epicenter was located one mile northeast of The Geysers, four miles west southwest of Cobb and six miles west northwest of Anderson Springs, the US Geological Survey reported.

Shake reports were made to the US Geological Survey from as close as Middletown and Calistoga and as far away as Pleasanton.

The quake's ground motion places it at level IV on the Modified Mercalli Intensity Scale, which means it was felt by many and caused damage.

“I do have some damage,” said longtime Anderson Springs resident Meriel Medrano. “I have a huge crack in my living room.”

Medrano said she also had a new crack in her bathroom.

The quake was the second in two days measuring 3.0 or above in magnitude. A Tuesday morning earthquake measuring 3.8 on the Richter scale and V on the Modified Mercalli Intensity Scale.

Medrano said she thinks her damage could have resulted from the effects of both quakes.

The Wednesday quake was “a pretty good doozy,” said Medrano, noting that it woke her up.

Medrano and other Anderson Springs and Cobb residents are concerned that AltaRock Energy's new geothermal drilling project – located up the mountain from her home – will increase seismicity in the already earthquake-prone area, as Lake County News reported earlier this week.

The company already has started drilling and is expected to start fracturing deep bedrock in August.
