  29. 海嘯 (Tsunami) 海嘯的英文通常被稱為Tsunami (發音: soo-NAH-mee)，來自日語「津波」，”tsu”指港口(harbor) ，”nami”指波浪(waves)。目前已愈來愈少人使用tidalwave，以便和潮汐作區別。海嘯是指海洋中綿延數百公里的波浪，在廣闊的深海大洋中其行進速度最快可高達每小時1000公里左右，2004年12月26日印尼蘇門答臘地震所引發的海嘯在75分鐘內便前進了600公里(亦即時速480公里/小時)。海嘯在靠近淺水區的速度則驟降，可疊加形成高度達數十公尺的水牆，這些水牆對海岸地區的衝擊往往能釀成巨大的傷亡。 Page created by W.

  30. Tsunami Generation: This animation by Prof. Miho Aoki from the University of Alaska Fairbanks Art Department provides a very nice look at how a tsunami can be generated by a subduction zone earthquake.

  31. Earthquake-generated tsunamis • Seafloor deformed by earthquake • Wave initiated with small amplitude and high speed in deep water • Speed decreases and amplitude increases in shallow water Page created by W. G. Huang

  32. 海嘯和一般的風所引起海浪兩者有許多的不同，主要的差異在於它們的來源，速度與尺度的大小海嘯和一般的風所引起海浪兩者有許多的不同，主要的差異在於它們的來源，速度與尺度的大小 Tsunamis and normal waves are many differences between the two. The primary differences are size, speed and source. Page created by W. G. Huang

Pacific Tsunami Warning Center PTWC Alaska Tsunami Warning Center ATWC Alaska DART station The PTWC was established in 1948, following the 1946 tsunami in Hawaii that left more than 150 people dead. The ATWC was established in 1967 as a result of the 1964 9.2 earthquake in Alaska that left 132 dead—122 of those deaths have been attributed to the tsunami that was generated.
