The impact of the rockslide included the creation of wave run up that shaved up to 400m of ice off the front of the Lituya Glacier and eroded or completely eradicated its rocky deltas. Over 30 million cubic meters of rock fell from a height of several hundred meters into the bay, creating the megatsunami. The earthquake caused a subaerial rockfall in the Gilbert Inlet.
(Note: this is the run up height of the wave and not the height of the wave as it hit the shore) Height of megatsunami, compared with Burj Khalifa, Empire State Building and Eiffel Tower. The retreats of these glaciers form the present "T" shape of the bay, the Gilbert and Crillon inlets. They are each about 12 miles (19 km) long and 1 mile (1.6 km) wide with an elevation of 4,000 feet (1,200 m).
Near the crest of the Fairweather Mountains sit the Lituya and the North Crillon glaciers. The two arms that create the top of the T-shape of the bay are the Gilbert and Crillon inlets and are a part of a trench on the Fairweather Fault. The narrow entrance of the bay has a depth of only 33 feet (10 m). Lituya Bay is an ice-scoured tidal inlet with a maximum depth of 722 feet (220 m). It is a T-shaped bay with a width of 2 miles (3 km) and a length of 7 miles (11 km). Lituya Bay is a fjord located on the Fairweather Fault in the northeastern part of the Gulf of Alaska. This is the largest and most significant megatsunami in modern times it forced a re-evaluation of large-wave events and the recognition of impact events, rockfalls, and landslides as causes of very large waves. The impact was heard 80 kilometers (50 mi) away, and the sudden displacement of water resulted in a megatsunami that washed out trees to a maximum elevation of 524 meters (1,719 feet) at the entrance of Gilbert Inlet. The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 30 million cubic meters (40 million cubic yards) and about 90 million tons into the narrow inlet of Lituya Bay, Alaska. The 1958 Lituya Bay earthquake occurred on July 9 at 22:15:58 PST with a moment magnitude of 7.8 to 8.3 and a maximum Mercalli intensity of XI ( Extreme). The lighter green areas along the shore indicate places where forests are younger than older trees (darker areas) that were not affected by the tsunami. The damaged trimline is still imprinted in the forest.
DON MEGGA ALASKA QUAKE BREWERY MOVIE
Because sometimes, you’re not interested in seeing that movie everyone’s talking about but are dying to know what the hubbub is about anyway.Because sometimes, you vaguely remember an old movie that had some sort of plot twist at the end of it, but can’t remember what it was.
Because sometimes, the surprise “spoiler” ending is the only reason you’d pay $11 to see what is otherwise a turkey of a film.
