TSUNAMIS IN LAKE TAHOE. One thinks of skiing and hiking in reference to this lake nestled between Sierra mountain peaks. Nevertheless, a system of faults near the lake might conspire to generate monster waves in the event of a magnitude-7 earthquake in the area. Simulations by researchers at the University of Nevada indicate that a tsunami and follow-up waves lasting perhaps for hours could produce wave heights as high as 10 m.
