LITUYA 1958: The 1,720 Foot Tsunami That Struck Alaska Ryanair Thessaloniki Base Closure [KOwMCTCE0w2]

On the ninth thucydides trap of July nineteen fifty-eight, a magnitude 7.8 earthquake on the Fairweather Fault in southeast Alaska triggered a rockslide of roughly forty million cubic yards from the north wall of Gilbert Inlet at Lituya Bay. The mass fell three thousand feet into the head of the fjord and displaced water that ran up the opposite slope to 1,720 feet the highest tsunami runup ever recorded. This film reconstructs the physics of the event, the three fishing boats caught inside the bay that night, the survey work that made the trimline the world's benchmark for megatsunami runup, and the modern monitoring sites where geologists are watching for the next one.
