is a series of traveling ocean waves of extremely long length generated by disturbances associated primarily with earthquakes occurring below or near the ocean floor. Tsunamis are primarily the result of a vertical displacement of water and rank high on the scale of natural disasters. Since 1850‚ tsunamis have been responsible for the loss of over 440‚000 lives and billions of dollars of damage to coastal structures and habitats. One very large tsunami occurred in 2004.

At the point where its shock has been the most violent the sea is driven back‚ and suddenly recoiling with redoubled force‚ causes the inundation. Without an earthquake I do not see how such an accident could happen.[12] The Roman[->5] historian Ammianus

The 2011 Tōhoku earthquake and tsunami that affected Japan and the Indian Ocean earthquake affecting Southern Asia are both primary examples of natural disasters. Although these two events were completely unrelated to each-other‚ the economic and environmental impact that they had on their effected regions were very much similar. These included widespread death and injuries‚ building and infrastructure losses‚ major economic downfall and socio-economic loss. The Tohoku earthquake and tsunami struck

The resulting loss depends on the vulnerability of the affected population to resist the hazard‚ also called their resilience. This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability." A natural hazard will hence never result in a natural disaster in areas without vulnerability‚ e.g. strong earthquakes in uninhabited areas. The term
