The 1958 Lituya Bay earthquake occurred on July 9, 1958, at 22:15:58 PST with a moment magnitude of 7.8 to 8.3 and a maximum Mercalli intensity of XI (Extreme). [4] The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 30 million cubic meters (40 million cubic yards) and about 90 million tons into the ...
The entrance is considered dangerous to navigation, especially when the tidal currents are running, but the interior of the bay provides good protection to anchored ships. [3] Lituya Bay is also famous for four recorded tsunamis, in 1854, 1899, 1936, and 1958. [4] [5] The bay is mentioned in Jack London's short story, "The Unexpected". (In that ...
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 ...
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.

This is a list of earthquakes in 1958. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events that occurred in remote areas are excluded from the list unless they generated significant media interest. All dates are listed according to UTC time. Not ...
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
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
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.
