Tsunamis are caused by earthquakes, landslides, ... Diagram showing several measures to describe a tsunami size, including height, inundation and run-up.
Diagram showing how earthquakes can generate a tsunami. Tsunamis in lakes can be generated by fault displacement beneath or around lake systems. Faulting shifts the ground in a vertical motion through reverse, normal or oblique strike slip faulting processes, this displaces the water above causing a tsunami (Figure 1).

Small tsunamis can also be caused by intense coastal storms, according to the U.S. Tsunami Warning System. These are known as meteotsunami because they are caused not by underwater earthquakes or ...
A volcanic tsunami, also called a volcanogenic tsunami, is a tsunami produced by volcanic phenomena.

The most devastating volcanic tsunami in recorded history was that produced by the 1883 eruption of Krakatoa. The waves reached ...
A tsunami can happen any time and there's a chance that a near shore tsunami beats the first warning," they said. "If you're on the coast and feel an earthquake, get to higher ground immediately ...
The tsunami was the result of melting glacial ice, which caused a landslide that displaced water in a Greenland fjord. The waves it created bounced back and forth across the fjord for nine days.
