Lituya BayA flying boat dropped Paddy Sherman’s mountaineering expedition at Lituya Bay on June 17, 1958. Lituya Bay Rockslide [4] Lituya Bay (Figure 1) is a T-shaped bay in southeast Alaska with Gilbert Inlet to the north and Crillon Inlet to the south forming the branches of the ‘‘T.’’ On the evening of 9 July, 1958, a magnitude 7.7 earthquake occurred along the Fair-weather Fault. La Palma is currently the most volcanically.. Megatsunami. Here's OSU's small-scale tsunami simulation in action. It is a T-shaped bay with a width of 2 miles (3 km) and a length of 7 miles (11 km). For The Lituya Bay tsunami only killed 2 people, while the Indian Ocean tsunami killed over 200,000, but imagine if the Lituya Bay tsunami happened in a place like Hong Kong. Our simulation results compare favorably with field observations as well as a scaled laboratory experiment and numerical studies.
