April 1, 1946: The April Fools tsunami, triggered by an earthquake in Alaska, killed 159 people, mostly in Hawaii. July 9, 1958: Regarded as the largest recorded in modern times, the tsunami in Lituya Bay, Alaska was caused by a landslide triggered by an 8.3 magnitude earthquake.
Prior to the July, 1958 tsunami Don J. Miller of the United States Geological Survey had been studying evidence for the occurrence of large waves in Lituya Bay. He had documented evidence for at least four previous large waves with estimated dates of 1936, 1899, 1874 and 1853 (or 1854).
