Between 1990 and 2000, over 14 major tsunami events affected the world’s coastlines, causing devastation and loss of life. These events made scientists aware that tsunami have been underrated as a major hazard, mainly due to the misconception that they occur infrequently compared to other natural disasters. However this message did not get effectively translated into warning and response. The disastrous Indian Ocean Tsunami of December 26, 2004 revealed the weaknesses in warning systems, while the Japanese Tohoku Tsunami of March 11, 2011 revealed the flaws in perception and preparation. Both reinforced the point that tsunami larger than living memory can occur along any coastline. Evidence for past great tsunami, or mega-tsunami, has also been discovered along apparently aseismic and protected coastlines, such as those of Australia and Western Europe. These mega-tsunami are caused either by huge submarine landslides or the impact of asteroids and comets with the ocean. With a large proportion of the world’s population living on the coastline, the threat from tsunami cannot be ignored. Were a mega-tsunami to occur today, the death toll would be in the tens of thousands, while the damage would exceed that of any historical disaster.
Tsunami: The Underrated Hazard comprehensively describes the nature and process of tsunami, outlines field evidence for detecting the presence of past events, and describes particular events linked to earthquakes, volcanoes, submarine landslides, and asteroid impacts. While technical aspects are covered, much of the text can be read by anyone with a high school education. The book will appeal to students and researchers in geomorphology, earth and environmental science, and emergency planning, and will be attractive for the public interested in natural hazards and new developments in science.
