The first edition of this book provided readers with a complete examination of the tsunami phenomenon in Hawaii. This second edition adds many eyewitness accounts of the tsunamis of 1946 and 1960 and expands its coverage to include major tsunamis in the Mediterranean and off the coasts of Japan, Chile, Indonesia, Fiji, Alaska, California, Newfoundland and the Caribbean. Photographs and accounts of experiencing tsunami firsthand are placed within the framework of the how and why of tsunamis, our scientific understanding of these phenomena and the state of the tsunami warning system, which is widely used to forecast and measure tsunamis and prepare coastal areas for possible strikes.
