What happened in the Lituya Bay tsunami?
The impact of 40 million cubic yards (30.6 million cubic meters) of rock hitting the water produced a local tsunami that swept the entire length of the Lituya Bay and over the La Chaussee Spit. This wave stripped all vegetation and soil from along the edges of the bay.
Is Lituya Bay the biggest tsunami?
It caused significant geologic changes in the region, including areas that experienced uplift and subsidence. It also caused a rockfall in Lituya Bay that generated a wave with a maximum height of 1,720 feet – the world’s largest recorded tsunami.
Who died in the Lituya Bay tsunami?
Orville Wagner and his wife, Mickey, were killed when their boat was sunk after being hit by the wave.

Both boats were anchored about a mile up Lituya Bay from the entrance.
How fast did the Lituya Bay tsunami travel?
This rockslide caused water to surge over the opposite wall of the inlet to a maximum altitude of 1,740 feet, and generated a gravity wave that moved out the bay to the mouth at a speed probably between 97 and 130 miles per hour.
What time did the Lituya Bay tsunami occur?

A tsunami with a record run-up height of 1720 feet occurred in Lituya Bay, Alaska On the night of July 9, 1958, an earthquake along the Fairweather Fault in the Alaska Panhandle loosened about 40 million cubic yards (30.6 million cubic meters) of rock high above the northeastern shore of Lituya Bay.
What was the impact of the tsunami on the Philippines?
It caused significant geologic changes in the region, including areas that experienced uplift and subsidence. It also caused a rockfall in Lituya Bay that generated a wave with a maximum height of 1,720 feet – the world’s largest recorded tsunami.
How high did the rocks fall from the Lituya Bay?
The rocks fell from an elevation of about 3000 feet (914 meters). The impact of 40 million cubic yards (30.6 million cubic meters) of rock hitting the water produced a local tsunami that swept the entire length of the Lituya Bay and over the La Chaussee Spit. This wave stripped all vegetation and soil from along the edges of the bay.
