The giant waves of Lituya Bay | Geophysical Institute
2012年1月18日 · Lituya Bay, on the Pacific coast about 100 miles southeast of Yakutat and 40 miles west of Glacier Bay, is the site of the largest splash wave ever recorded. In 1958, a magnitude 8.3 earthquake triggered a tremendous landslide into the ocean.
Lituya Bay - Geophysical Institute
The crossbar part of Lituya Bay is the glacier-filled trench of the Fairweather fault, an active break slicing through the mountains roughly parallel to the coast. At some time in the recent past, a weakness in the rock strata allowed a breach to develop connecting the Fairweather trench to the ocean, and so Lituya Bay was formed.
Lituya Bay on the Rise - Geophysical Institute
2003年6月12日 · LITUYA BAY—With every distant roar, be it from Pacific surf crashing into rocks or jets flying overhead, we thought of 1958. That was the year a massive earthquake ripped through the back of the Lituya Bay, a mountain collapsed into deep water, and a giant wave swept through the bay.
Lituya Bay's Deadliest Hazard - Geophysical Institute
2024年12月19日 · Lituya Bay lies perpendicular to the Pacific Ocean coastline, is about seven miles long and varies from three-fourths of a mile to two miles wide. The entrance to the bay is about 1,000 feet across at low tide, and the bay’s tidal fluctuations create a strong current at the entrance recorded to be as fast as 13.8 miles per hour (12 knots ...
Melting glaciers contribute to Alaska earthquakes
2021年3月18日 · In 1958, a magnitude 7.8 earthquake triggered a rockslide into Southeast Alaska’s Lituya Bay, creating a tsunami that ran 1,700 feet up a mountainside before racing out to sea. Researchers now think the region’s widespread loss …
Bonsai trees tell of winters long past - Geophysical Institute
2022年6月23日 · Here, about 10 miles north of Lituya Bay, it is breezy enough to be chilly here even on this summer day. The exposure makes it easy to imagine winter storms blasting through. “Nothing is stopping the winds between here and Hawaii,” Gaglioti says, pointing to the blue-green expanse of ocean that ends at a line that looks like you might fall ...

The icebergs seen in the water of Lituya Bay, foreground, were knocked off the glacier by the landslide falling into the bay from a slope to the right of the photograph. Photo by Byron Hale.
A half century in a difficult, dynamic place - Geophysical Institute
2022年7月7日 · As a 24-year-old, he camped on Cenotaph Island within Lituya Bay, dug soil pits, and almost got fired for scheming to get his climbing buddies to join him for an ascent of nearby Mount Crillon. A bit later, a retired scientist named Richard Goldthwait of Ohio State University looked to this broad-shouldered young man who was intrigued with the ...

1979年2月28日 · As far as is known, the three people were standing on the gently sloping shore near their beached boat when the first seismic waves arrived from an earthquake centered a hundred miles away beyond Lituya Bay, to the southeast. Suddenly the ground beneath their feet fell away and plunged more than a hundred feet below the sea.
Rugged science on the Southeast coast - Geophysical Institute
2022年6月16日 · The leader of our expedition, Quaternary geologist Dan Mann, has guided just a dozen people to the spongy terraces north of Lituya Bay in the last 45 years. One reason few have visited is that the high benches are very hard to reach.
