Tsunamis in Lake Tahoe?

Graham Kent, a geophysicist at the Scripps Institute of Oceanography at UC San Diego, has found evidence that faults crossing through Lake Tahoe are capable of producing magnitude 7 earthquakes. These earthquakes are capable of producing tsunamis up to 30 feet tall! Major quakes on seismic faults that run beneath Lake Tahoe have ruptured the earth’s crust there roughly every 3,000 years or so, and scientists are trying to determine just when the last big one hit. Although the temblors may be few and far between, they’ve thrust masses of ground up or down by 10 feet or more in the past, say the scientists, who have dug trenches where past quakes have struck on the shore of the Nevada community of Incline Village.
