In July 1958, an earthquake shook about 30 million cubic meters of rock into Alaska’s Lituya Bay, and the splash stripped forest from a slope 1,720 feet high, taller than the Empire State Building; Howard Ulrich and his 7-year-old son rode the wave out in their fishing boat
The July 9, 1958 Lituya Bay megatsunami in southeast Alaska stripped forest from a mountainside 524 m (1 720 feet) above sea level after an earthquake-triggered rockslide crashed into Gilbert Inlet. The extraordinary height marked the water’s run-up on a slope, not a wave of that height traveling through the bay; two people died, while Howard Ulrich and his 7-year-old son survived aboard a fishing boat lifted by the wave.
