Tsunami refers to a natural disaster that is characterized by a set of long waves brought on by an abrupt movement of the ocean, which is typically caused by an earthquake near or beneath the ocean's surface. This force generates waves that travel in all directions away from the source, occasionally spanning entire basins in the ocean. The devastation caused by tsunamis on both human and natural life is immense. The long-term effects of a tsunami include disease, destruction, and death. It also has significant environmental impacts on human beings and wild life. Unique buoys can be left in the sea for detecting tsunami waves early, which gives coastal areas enough time to evacuate. Furthermore, satellites, weather equipment, and radar are also used to gather information and make forecasts about impending tsunamis. This book includes some of the vital pieces of work being conducted across the world, on various topics related to the long-term effects and mitigation of tsunamis. It will serve as a reference to a broad spectrum of readers.
