On July 9, 1958, an earthquake occurred in the Alaska Panhandle. The quake dislodged rocks above the northeastern shore of Lituya Bay, causing a rockslide that fell from impressive heights into the water. This chain reaction set off a megatsunami that devastated the shoreline of the entire bay. The tallest wave ever recorded stripped trees from the southwest shoreline of Gilbert Inlet, reaching approximately 1,720 feet (524 meters) above the surface of the bay. Amazingly, the local tsunami caused only two fatalities, and a father and son survived the event by riding a huge wave in their fishing boat.
