THIS QUAKE HAS BEEN UPGRADED FROM 3.4 TO 3.5 IN MAGNITUDE.

THE GEYSERS – The Geysers and Cobb area experienced a 3.5-magnitude earthquake Tuesday morning.

The temblor hit at 10:51 a.m. four miles north of The Geysers and 10 miles southwest of Clearlake, the US Geological Survey reported.

The survey said the quake was poorly constrained and occurred at the earth's surface.

Cobb resident Roger Kinney, a frequent contributor regarding earthquake reports in the area, said he was standing outside when the quake occurred, and that he saw his home shudder as a result of it.

The US Geological Survey received three shake reports – one from Kelseyville, one from Middletown and one from San Jose.

A 3.0-magnitude earthquake was reported at The Geysers on Oct. 4, as Lake County News has reported.
