WebA tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. WebTsunamis are ocean waves triggered by: Large earthquakes that occur near or under the ocean. Volcanic eruptions. Submarine landslides. Onshore landslides in which large volumes of debris fall into the water. Scientists do not use the term "tidal wave" because these waves are not caused by tides. Tsunami waves are unlike typical ocean waves ...

The distinguishing feature for a tsunami earthquake is that the release of seismic energy occurs at long periods (low frequencies) relative to typical tsunamigenic earthquakes. Earthquakes of this type do not generally show the peaks of seismic wave activity associated with ordinary events. A tsunami earthquake can be defined as an undersea earthquake for which the surface wave magnitude Ms differs markedly from the moment magnitude Mw, because the former is cal… WebFind 9 ways to say SURFACE WAVE, along with antonyms, related words, and example sentences at Thesaurus.com, the world's most trusted free thesaurus. sign in to my domain

WebThe three types of seismic waves are: P-wave- the most feeble and fastest of the three and is the first one released by an earthquake ; S-wave- slower wave than the p-wave but is much stronger.The P and S-wave are called body waves and they propagate vertically from the focus (the origin of the earthquake) so the ground moves up and down.; Surface wave- … WebThe deeper the water, the greater the speed of tsunami waves will be. For example, at the deepest ocean depths the tsunami wave speed will be as much as 800 km/h, about the same as that of a jet aircraft. Since the average depth of the Pacific ocean is 4000 m (14,000 feet) , tsunami wave speed will average about 200 m/s or over 700 km/h (500 mph). WebTsunami (pron: 'soo-nar-me') is a Japanese word: 'tsu' meaning harbour and 'nami' meaning wave. Tsunami are waves caused by sudden movement of the ocean surface due to … sign in to my dstv account
