Such tremors aren’t unfamiliar in this part of the world, leaving the waters around Barry Arm marked as a danger zone for the foreseeable future. Damage from the 1958 Lituya Bay megatsunami can be seen in this oblique aerial photograph of Lituya Bay, Alaska as the lighter areas at the shore where trees have been stripped away. Map of Lituya Bay showing setting and effects of giant wave that occurred in 1853 or 1854 78 20. Map of Lituya Bay showing trimlines of one or more giant waves that occurred between 18 76 19. Worst case scenario would of course be a major earthquake to strike the region and send the entire slope crashing down. Map of Lituya Bay showing setting and effects 1936 giant waves 68 18. You can read more about this event in 60 years ago: The 1958 earthquake and Lituya Bay megatsunami. It caused significant geologic changes in the region, including areas that experienced uplift and subsidence. Landslides in Lituya Bay in Southeast Alaska following a magnitude 7.8 earthquake on the Fairweather Fault produced a megatsunami with 1,720 feet of run-up. “Initial research indicates that other communities and infrastructure in Prince William Sound may also be at risk of a measureable tsunami and dangerous currents, including Valdez, Cordova, Tatitlek and Chenega.” Description On July 10, 1958, a magnitude 7.7 earthquake occurred on the Fairweather Fault in southeast Alaska. There is little in the way of major population centers nearby, but ADGGS notes that a tsunami “could have devastating local effects on those who live, work, and recreate in and around Whittier and in northern Prince William Sound.” Lituya memiliki kedalaman sekitar 219 meter. Bentuk geografinya unik dengan panjang sekitar 11,3 kilometer dan lebar hingga 3,2 kilometer. Teluk ini berada di Patahan Fairweather di bagian timur laut Teluk Alaska. Some 200 million metric tons of rock slid down the mountain in a crash that must have been deafening. Inilah asal muasal terminologi Megatsunami Lituya Bay, atau Tsunami Raksasa Teluk Lituya. Those first rocks shoved more rocks, and then more still. “Unfortunately, access is currently restricted due to the risk associated with being on the water in the vicinity of the landslide.” The friction that held silt to silt and rock to rock began giving way. “There is much that is unknown, most notably the thickness of the moving mass,” writes landslide expert Dave Petley for the AGU. Mary Elizabeth Fleck Marvin Robert Kay Jeremy Scott Kay Ronald. A failure could happen at any moment, although it’s not clear how large such a slide might be or what amount of material might fall in the water. In the case of the Barry Arm landslide, it has already been seen moving up to several centimeters per day in recent weeks.

In that instance, an earthquake triggered a massive rockslide that generated a mega-tsunami with a wave that reached a dizzying height of over 1,700 feet.
