THE GEYSERS – A 3.0 earthquake hit The Geysers area early Wednesday.

The quake occurred at 7:15 a.m., and was centered one mile west northwest of The Geysers and six miles west southwest of Cobb. The quake was measured at a depth of 2.5 miles.

The larger quake was followed by a 1.3 magnitude quake at 7:48 a.m., centered two miles north northeast of The Geysers and four miles west southwest of Cobb, 2.1 miles deep. Another smaller quake, a 1.2, happened at 4 p.m. right at the location of The Geysers.

The Geysers has a consistently high amount of seismic activity, which US Geological Survey seismologist David Oppenheimer said is due to geothermal activity in the area.

As for quakes 3.0 and above, The Geysers and Lake Pillsbury areas had several of those larger quakes in the spring, but in recent months the greater magnitude activity has tapered off.

Small quakes continue on an almost daily basis at Pillsbury, which had a 2.0 quake at 1:45 p.m. three miles north northwest of Lake Pillsbury. That location is several miles from the epicenter of the larger quakes recorded this spring.
