The Geysers is an active geothermal area within the Clear Lake volcanic field in Northern California. The earthquake activity in the Geysers area is quite variable over time, in terms of the number of events and their magnitude range.
M3.5 2007/09/17 07:43 ENE of Hidden Valley Lake, CA. not far from the geysers within the Clear lake volcanic field.
There were no earthquakes (ML >= 2.5) observed in the area of the geothermal field between 1949 and 1975.
From April 1945 to May 1971 the Jupiter system of force was extremely low with a corresponding period of global warming. Earthquakes would be small during the releasing period after January 1941 high Jupiter system of force. Beginning in 1971 the Jupiter system of force began to rise to a high April 1981 and a period of global cooling which meant a tightening of the Earth surface crust. After 1981 global warming began to returned as the Jupiter force system decreased to a low point in August 1989 remaining low until September 2010.

Starting in 1976 earthquakes were observed by PG&E who own and manage geothermal electrical generating plants in the area. The geothermal field rate of earthquakes steadily increased to a rate of at least 12 earthquake (ML >= 2.5) per year since 1984. The maximum annual rate was 26 earthquakes (ML >= 2.5) which occurred in 1988 (this is equivalent to 40 percent of the annual rate for the entire central coast ranges).

The number of seismic events at The Geysers is increasing.
During the week of September 10, 2007 to September 17, 2007 there were 89 events reported at The Geysers, Ca. Two were greater than M2.5 occurring near the end of the period shown. The Geysers are associated with water having access to magma near the surface. Small earthquakes would be recorded as the steam built up and exploded toward the surface. Larger earthquakes like M3.5 on 2007/09/09 and M2.9 and M2.7 on 2007/09/18 would suggest movement along the fault line and greater access to the magma.
