A subsequent analysis to the 1999 one that examined the wider impact of the event found that the rockfall itself was inadequate to explain the resulting accounts and evidence. In Gilbert Inlet, which branches north at a right angle from the head of the bay, Miller found that a stream delta had vanished and 1,300 feet of ice had sheared off the end of Lituya Glacier. 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 Icy Bay wave may be the largest since a magnitude 8 earthquake shook much of a mountain into Lituya Bay in 1958.

In the morning, he learned of the disaster in Lituya Bay and chartered a float plane to take him there. The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 40 million cubic yards into the narrow inlet of Lituya Bay, Alaska. Several scientists have since modeled the conditions of that day in Lituya Bay to try to determine what happened. The earthquake triggered a massive landslide into the waters at the head of the bay. All five deaths occurred in the water, which speaks to the nature of earthquake hazards in Southeast.

Subsequent mathematical modeling at the Los Alamos National Laboratory (Mader, 1999, Mader & Gittings, 2002) supported the proposed mechanism as there was indeed sufficient volume of water and an adequately deep layer of sediments in the Lituya Bay inlet to account for the giant wave runup and the subsequent inundation. In 2016, an entire mountainside failed and ran out onto the Lamplugh Glacier. Approximately 90,000 buildings and many wooden houses were destroyed.
