Stardust Bay is named for a fishing vessel wrecked on a steep, high‐energy beach on the pacific coast of Sedanka Island. This bay is the site of an ongoing study by the U.S. Geological Survey of very large tsunamis.
A massive landslide occurred in the Taan Fjord of Icy Bay in Wrangell-St Elias National Park, Alaska on October 17, 2015. The event generated a local mega-tsunami that sheared trees at an elevation of more than 500 feet (152.4 meters) on a peninsula within the fjord.
The March 1964 Alaska earthquake was the strongest earthquake in American history, measuring 9.2 on the Richter scale. The quake triggered a tsunami that destroyed Chenega, an Alaska Native village on Knight Island in Prince William Sound.
Lituya Bay is famous for four recorded tsunamis in 1854, 1899, 1936, and 1958. The 1958 mega-tsunami was caused by an earthquake that generated a landslide at the head of the bay in Gilbert Inlet.
