| Abstract | Over 700 earthquakes occurred in the vicinity of Lassen Peak, California from February 1981 through December 1983. These earthquakes define a broad, northwest trending seismic zone that extends from the Sierra Nevada through the Lassen Peak area and either terminates or is offset to the northeast about 20 kilometers northwest of Lassen Peak. Approximately 25% of these earthquakes are associated with the geothermal system south of Lassen Peak. Earthquakes in the geothermal area generally occur at depths shallower than 6 kilometers. |
