Tectonic plates are pieces of Earth 's crust. These tsunamis are less frequent, but more hazardous than regional tsunamis, as they usually start as a local tsunami that causes extensive destruction to a shoreline near the source, and the waves continue to travel across an entire ocean basin with sufficient energy to cause additional casualties and destruction on shores more than a 1,000 km. What causes a tsunami essay? Tsunami is a phenomenon where a series of strong waves that are responsible for the surge in water sometimes reach the heights in many meters. This is a natural disaster that is caused due to the volcano eruption in the ocean beds. Also, a phenomenon like landslides and earthquakes contributes to reasons for a tsunami. Tsunamis are caused by earthquakes or other seismic eruptions on ground of an oceans and can cause massive tidal waves, which run with enormous force on land, causing great devastation. Especially in regions with only few tsunamis, the damage is often drastic, as the population does not expect tsunamis and thus hardly takes any protective. Definition: Tsunamis are water waves caused by earthquakes, volcanic eruptions, or landslides. In deep water tsunamis have long wavelengths, short wave heights, and travel up to 30 mph. As tsunamis enter shallow water they slow down, and the waves increase significantly in height. Tsunamis do not have to have large wave heights to be damaging. Tsunami Preparedness. A tsunami is a series of large ocean waves often generated by large undersea earthquakes that displace the ocean floor, and a tsunami can also be caused by generated by landslides and volcanic eruptions.
