The Mother of Inland Tsunamis
April 24, 2011 by Paul Hatfield
One of the worst tsunamis to strike California did not occur along the coast, but near the Nevada border at Lake Tahoe.
It was triggered my a massive landslide near present day Homewood (about midway on the West Shore) and sent water sloshing back and forth across the lake as if it were a bathtub. The waves were hundreds of feet high. McKinney Bay was created.

Although a repeat of the massive landslide that triggered the event is unlikely, a 7.0 earthquake could produce tsunami waves around thirty feet tall which would ravage properties along the beaches, obliterate Kings Beach on the North Shore and cause widespread damage to South Lake Tahoe.
