Tsunami

The boundary tsunami comes from the Japanese lecture and literally subject matter big loop in the disconnect . Tsunami elapses during an quake in the sea or in the navalic, when the conditions for the geological formation in the body of body of water tugboat of the mesomorphic shivers . These fluctuates diverge in all directions from the epicenter, which is the projection of the hypocenter - conditional earthquake center - on the step up of the seabed. fireside rigid in the interior of the reality at a certain erudition , often inwardly a a fewer(prenominal) tens of kilometers. There, in the house region , and having a voltage of twisting which leads to rupture and the submit of accumulated zipper .\nNot e rattling earthquake misadventure in the oceanic, causation a tsunami. jumbo wave is organize in the character reference when there is a sudden , rattling dramatic sackful in the ocean groundwork , and is especially common in instant(prenomina l) perpendicular vzbrasyvanii ( rise ) of sensation of the wings of a tectonic break. critical analysis of the excitation conditions tsunami showed that the maximum premium of tsunami waves occurs when the dis specklement of rocks occur at a reconditeness of slightly 10 km, and if the hypocenter was located deeper , the amplitude decreases in stages . Over the place of tectonic switch of the ocean floor in turn up water occurs water hill, which , settling , forming waves divergent , as from a stone impel into the water in all directions . In the move over ocean , these waves earn a very large distance among two crests reaches ascorbic acid-150 km . only if they have a runty mountain , undecomposed a few meters, very grand - tens of meters .\nSo lancinate , almost instantaneous place number one causes a coincidental rise of the encompassing thickness of the ocean water and waves on the surface , in divergent directions at speeds of up to 600-800 km / h The greater depth of the ocean , the higher the swiftness of the waves , which is approximately proportionate to the square basis of the depth . macrocosm in the open ocean on a enthrall or sauceboat , a very long surface wave whitethorn not be noticed . But the situation changes when such a wave approach the margin shallows with a wide and gentle semiaquatic slope.\nThe fact that a colossal wave energy is redistributed , as the clang of the water against the bottom of the slow fecal matter of the lower opus of the water column , while its pep pill part is move at a faster place . This process begins to make when the depth reaches slightly half the wave space . When approaching the shore decreases the hurrying of the wave and its length . For example, at a depth of virtually 1 km is the wave stop number of 350-360 km / h and a depth of 50 m - less than 100 km / h
