What was the deadliest tsunami?

Answer 1

Possibly the most dangerous tsunami occurred in Alaska, in which the highest known tsunami was recorded. Lituya Bay is a large inlet on the coast of Alaska. It is believed that an earthquake of either 7.9 or 8.3 on the Richter scale, occurred along a nearby faultline, part of the Pacific Rim of Fire. Around 40 million cubic yards of dirt and glacier were shaken loose from a mountainside at the head of the Bay, resulting in a tsunami (series of waves), the highest of which reached over 5oo metres. Although the only witnesses to the event were people in a couple of fishing boats, the height was able to be determined by scientists finding the high water mark, where the water reached its highest point on the nearby land.

Quote from the Related Link: "The tsunami that occurred on December 26, 2004 was the worst tsunami ever recorded, in terms of lives lost."
The Lituya Bay wave has been described as the largest tsunami ever recorded in modern times, and has been given the title "mega-tsunami". It was caused by a huge landslide, triggered by an earthquake in excess of magnitude 8. When the wave crossed the bay it ran up the valley walls to a height of more than 570 m at its maximum (1700 ft+) and possibly over 100 m for the rest of the bay area.
