Quick Answer

The 1958 Lituya Bay megatsunami in Alaska had a run-up of about 524 meters, the highest ever measured.

The Full Story

Although not a major ocean-wide tsunami, the 1958 Lituya Bay event produced the tallest known wave run-up ever recorded. A magnitude 7.8 earthquake triggered a massive landslide into the narrow fjord, generating a wave that stripped trees up to about 524 meters above sea level on the surrounding slopes. The event killed two people in the bay and destroyed boats and shoreline areas. Because the geography was so confined, the wave rose to an extraordinary height. Lituya Bay is now a classic example of how landslides can create extreme local tsunamis.
