A tsunami is a natural disaster characterized by a sequence of swiftly moving waves in the ocean, triggered by volcanic eruptions, strong earthquakes, or landslides inside the ocean. They are mainly generated by tectonic dislocations beneath the sea that result from shallow focus earthquakes along the zones of subduction. Tsunamis propagate through the full depth of the ocean from the surface to the floor. They have long wavelengths and have the capability of destroying trees, removing sand from beaches, dragging and tossing houses, vehicles and even destructing entire cities and towns. Tsunami modeling acts as an essential instrument for evaluating the possible effects of tsunami on the target shoreline in relation to all the earthquake scenarios that are considered in the earthquake model. This book aims to shed light on tsunamis, their generation, propagation, effects and modeling. With its detailed analyses and data, it will prove immensely beneficial to professionals and students involved in this area at various levels.
