Remembering the Tallest Known Mega-Tsunami That Destroyed a Bay in Alaska At 10:15 pm on July 10, 1958, the ground shook violently as an M7.8 earthquake occurred along the Fairweather Fault in Southeast Alaska. The strong shaking set loose an enormous rockfall, in which 40 million cubic yards of material (9 Superdomes!) tumbled down a steep slope into the narrow inlet of Lituya Bay. The impact was heard 50 miles (80 km) away […] Brains SnowBrains | July 17, 2020 0 Comments
