THE US GEOLOGICAL SURVEY HAS CHANGED THE RATINGS ON THESE TWO QUAKES.

THE GEYSERS – It was a one-two punch for The Geysers and Cobb areas late Tuesday afternoon, when two 3.1-magnitude earthquakes were reported within five seconds of each other.

However, the US Geological Survey later changed its report to show that the first quake was a 1.5 in magnitude and the second was 3.5 in magnitude.

The US Geological reported that the first quake occurred at 4:07 p.m. and was centered one mile from The Geysers, four miles west southwest of Cobb and six miles west northwest of Anderson Springs, at a depth of 1.2 miles.

The second quake, which was measured at a depth of one-tenth of a mile, had an epicenter located one mile north northeast of The Geysers, five miles west southwest of Cobb and six miles west northwest of Anderson Springs, the US Geological Survey reported.

The first quake resulted in one shake report from San Jose being submitted to the US Geological Survey, while five shake reports from areas including Clearlake Oaks, Sacramento, Mountain View, San Francisco and San Jose came in as a result of the second quake.

A 3.3-magnitude quake was reported near The Geysers Sunday evening, as Lake County News has reported.
