                                    Most Destructive Tsunamis

Tsunami is one of the most destructive natural disasters. A tsunami can be generated by any significant displacement of water in large water bodies. This displacement is generally caused by the movement of tectonic plates under the ocean floor during an earthquake. Glacial carving, volcanic eruption, landslides etc. are some other reasons of tsunamis. This article includes a list of most destructive tsunamis that showed us how vulnerable modern society is to the power of nature.
