Geography, Geology and Earth Science - Disaster Management
A tsunami is a series of waves in a water body, usually an ocean or a lake, caused by the displacement of a large volume of water. Earthquakes, volcanic eruptions and other underwater explosions have the potential to generate a tsunami. The wavelength of a tsunami wave is far longer than normal undersea currents or sea waves. They consist of a series of waves with periods ranging from minutes to hours, and wave heights of several metres. Tsunamis have an enormous destructive power, and majorly affect the coastal areas. They can also affect entire ocean basins. Tsunami modeling focuses on the necessary tool for assessing the impact at the target coastline of tsunamis corresponding to all earthquake scenarios considered in the earthquake model. This book discusses the fundamentals as well as modern approaches of tsunami modeling and hazard assessment. Different evaluations, methodologies and advanced studies on this discipline have been included herein. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in this area at various levels.
