Fritz and Hager found that a slide like the one at Gilbert Inlet could generate that much run-up because the rapid impact of the slide would bring a large air cavity into the water behind it, displacing far more water thanjust the volume of the rock. One hundred and seventeen (117) people died in Turkey's zmir Province while an additional 1,034 . . A wave tower collapsed and a cabin was damaged beyond repair. An 8.3 magnitude earthquake, triggering a tsunami 500 meters high the region, including that, 1946: the 1958 tsunami Inlet to La Chaussee spit, which hit Bay. [20] In particular, the amount of sediment apparently added to the bay, judging by the sea-floor shape, was much greater than could be explained by the rockfall alone, or even the rockfall and sediment disturbed by it, and the energy of the resulting waves from the rockfall and stirred-up sediment would not have been sufficient. ,Sitemap,Sitemap For Sale By Owner Broome County, Two were rescued from a dinghy after their boat sank, the others managed to pilot out of the bay on their own power, but at great risk, as the water continued to swirl unpredictably, and was littered with millions of tree trunks that had been ripped from the banks.
