Larger quake activity increases over weekend

EDITOR'S NOTE: THE TWO 3.0 QUAKES MENTIONED  HAVE BEEN DOWNGRADED TO 1.1 MAGNITUDE AND 2.8 MAGNITUDE, RESPECTIVELY.

 

LAKE COUNTY – The Labor Day weekend saw several sizable earthquakes occur around the county.


Before the weekend even got started, a 3.7-magnitude quake was reported in The Geysers area at 3:20 a.m. Friday, according to the Lawrence Berkeley National Laboratory's earthquake array.


Then, on Saturday, The Geysers saw two quakes measuring 3.0 in magnitude within eight seconds of each other.


The first 3.0 quake, which occurred at 1:48 a.m. at a depth of 1.6 miles, was centered one mile west of Anderson Springs, four miles south of Cobb and five miles east southeast of The Geysers, according to the US Geological Survey.


The 3.0 quake that followed it seconds later was measured at a depth of 0.6 of a mile and was centered in the exact same area one mile west of Anderson Springs, the US Geological Survey reported.


While no shake reports were made to the survey regarding the first quake, they received numerous reports on the second, with reports coming from Middletown, Covelo, Santa Rosa and Eureka to as far away as Santa Clara and Palmdale, the latter over 600 miles away.


Then, on Monday the US Geological Survey reported a 3.2-magnitude quake occurred near Lake Pillsbury at 1:22 a.m.


That quake, at a depth of 6.6 miles, was centered three miles east southeast of Lake Pillsbury, 16 miles north of Upper Lake and 19 miles north of Nice, the survey reported.


Only one shake report was received on the Pillsbury quake – it came from the San Francisco area, according to US Geological Survey records.


The last series of quakes to hit the county measuring 3.0 or above occurred early in July, when The Geysers area experienced five such quakes in just a few weeks, as Lake County News reported earlier this summer.
