Tahoe earthquake felt in Carson Valley

Carson Valley residents reported feeling a 3.93 earthquake centered in the middle of Lake Tahoe on Sunday morning.

The University of Nevada, Reno, Seismology Lab said the earthquake occurred at 8:33 a.m.

According to the U.S. Geological Survey’s Did You Feel It there were around a dozen of the 1,104 responses in Carson Valley.

Most of the responses were from around Lake Tahoe and Truckee.

According to the university, there were five aftershocks of decreasing size over the following half-hour.

Large faults cross the bottom of Lake Tahoe, which is one of the world’s deepest freshwater lakes.

Researchers from the Scripps Institute believe that a magnitude 7 earthquake occurs ever 2,000-3,000 years with the largest fault in the Basin to have last ruptured 4,100-4,500 years ago.

Sunday’s earthquake appears to have occurred near the south end of the Incline Village Fault.

Lake Tahoe and Western Nevada are along the Walker Lane which extends east of the Sierra from south of Death Valley to north of Pyramid Lake. According to researchers, the Walker Lane takes up 15-25 percent of the boundary motion between the Pacific and North American plates with the rest taken up by the San Andreas Fault.
