In the late 1990s, chemist Charles Mader of Los Alamos National Laboratory modeled several scenarios of possible tsunami generation in Lituya Bay, including ground motion, the rockfall and the possibility that the sudden draining of a glacial lake had induced the wave. The epicenter of the quake was at latitude 58.37N, longitude 136.67W near the Fairweather Range, 7.5 miles (12.1km) east of the surface trace of the Fairweather fault, and 13 miles (21km) southeast of Lituya Bay.

Fritz and Hager found that a slide like the one at Gilbert Inlet could generate that much run-up because the rapid impact of the slide would bring a large air cavity into the water behind it, displacing far more water thanjust the volume of the rock. Don Miller, the geologist, was on a USGS barge in Glacier Bay when the earthquake struck.
