How do landslides cause tsunamis?
Tsunamis are large, potentially destructive sea waves, most of which are formed as a result of submarine earthquakes, but which may also result from the eruption or collapse of island or coastal volcanoes and the formation of giant landslides on marine margins. These landslides, in turn, are often triggered by earthquakes. Environmental damage by these tsunamis include coral reef destruction, contamination of wells and other sources of fresh water by salt water, denudation of trees and other types of dry-land vegetation, accelerated beach erosion, and fish and other marine life fatalities due to abnormal wave action. The flooding and powerful wave action of the tsunami may potentially cause damage to man-made containment vessels of petroleum products, chemicals, and garbage landfills, resulting in toxic leakage, which in turn has the potential to pollute both coastal land and ocean environment. Tsunami waves can be generated from displacements of water resulting from rock falls, icefal
