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]
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.

“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, U.S. 1958 Lituya Bay, Alaska earthquake and megatsunami: Earthquake-triggered landslide: On the night of 9 July 1958, an earthquake on the Fairweather Fault in Alaska loosened about 40 million cubic yards (30 million cubic meters) of rock 3,000 feet (910 m) above the northeast shore of Lituya Bay.

Lituya Glacier is a tidewater glacier in the U.S. state of Alaska. Located at 58°43′25″N 137°29′33″W / 58.72361°N 137.49250°W / 58.72361; -137.49250 inside Glacier Bay National Park and Preserve , its source is in the Fairweather Range and it feeds into Lituya Bay on the gulf coast of Southeast Alaska
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 ...
The 1958 earthquake had a magnitude of 7.8 and led to a major landslide in Lituya Bay, Alaska. This resulted in a 1,720-foot (524-meter) tsunami that crashed into a mountainside, the largest ever recorded tsunami run-up. [29] The 2012 magnitude 7.8 earthquake struck off the western coast of Haida Gwaii at around 8:10pm Pacific Time on Saturday ...
