地球内部过程 Tsunamis海啸 and Coastal Flooding Coastal areas, especially around the Pacific Ocean basin where so many large earthquakes occur, may also be vulnerable易于 to tsunamis
地球内部过程 Tsunamis海啸 and coastal Flooding These are seismic sea waves sometimes improperly called " tidal waves,although they have nothing to do with tides. When an undersea or near-shore earthquake occurs, sudden movement of the sea floor may set up waves traveling away from that spot, like ripples in a pond caused by a dropped pebble. Contrary to modern movie fiction, tsunamis are not seen as huge breakers in the open ocean that topple ocean liners in one sweep In the open sea, the tsunamis are only unusually broad swells on the water surface 环境迪顶学 minoucntalocelogu ,率

地球内部过程 Tsunamis海啸 and coastal Flooding As tsunamis approach land, however, they develop into large breaking waves, as the undulating起伏 waters“ touch bottom”near shore. these breakers can easily be over 15 meters high in the case of larger earthquakes. Several such breakers may crash over the coast in succession/*E; between waves, the water may be pulled swiftly seaward, emptying a harbor'a it or bay, and perhaps pulling unwary粗心 onlookers旁观者 along 环境迪顶学 minoucntalocelogu ,率
