Lituya Bay is a fjord located on the Fairweather Fault in the northeastern part of the Gulf of Alaska. It is a T-shaped bay with a width of 2 miles (3 km) and a length of 7 miles (11 km). [8] Lituya Bay is an ice-scoured tidal inlet with a maximum depth of 722 feet (220 m). The narrow entrance of the bay has a depth of only 33 feet (10 m). [8]
“The most noteworthy of these tsunamis was in 1958, when a landslide entered the Lituya Bay Fiord in Glacier Bay and generated a wave that went 1,700 feet up the opposite side of the fiord ...
Lituya Bay, Alaska: Unknown: On 27 October 1936, a megatsunami occurred in Alaska's Lituya Bay with a maximum breakthrough height of 490 feet (149 m) in Crillon Inlet at the head of the bay. All four eyewitnesses to the wave in Lituya Bay survived and described it as being between 100 and 250 feet (30 and 76 m) high as it traveled across the bay.
Lituya Bay (/ l ɪ ˈ tj uː j ə /; Tlingit: Ltu.aa, [1] meaning 'lake within the point') [2] is a fjord located on the coast of the south-east part of the U.S. state of Alaska. It is 14.5 km (9 mi) long and 3.2 km (2 mi) wide at its widest point. The bay was noted in 1786 by Jean-François de Lapérouse, who named it Port des Français ...
On July 9, 1958, an earthquake along the Fairweather Fault loosened about 40 million cubic yards of rock above Lituya Bay. The impact of this enormous volume of rock falling from approximately 3,300 feet (1,000 m) produced locally the largest recorded tsunami (an estimated 1,700 feet (520 m) high) and devastated the entire bay.

A study of Lituya Bay in 1953 concluded that sometime around 1874, perhaps in May 1874, another megatsunami occurred in Lituya Bay in Alaska. Probably occurring because of a large landslide on the south shore of the bay in the Mudslide Creek Valley, the wave had a maximum run-up height of 24 metres (80 ft), flooding the coast of the bay up to ...
