Which earthquake generated the highest tsunami run-up ever recorded?
Quick Answer
The 1958 Lituya Bay event in Alaska produced the highest tsunami run-up ever recorded. A landslide-triggered wave reached about 524 meters up the slope.
The Full Story
The Lituya Bay megatsunami occurred in Alaska on 9 July 1958 after a major earthquake triggered a massive rockfall into the bay. The resulting wave climbed to an astonishing run-up height of about 524 meters, the highest measured anywhere on Earth. This was not a typical ocean-crossing tsunami but a local megatsunami caused by the sudden displacement of water. It is one of the most dramatic examples of how landslides can amplify earthquake effects.
