Characteristics When the wave enters shallow water, it slows down and its amplitude (height) increases.
Where do tsunamis occur?

Volcanoes, large earthquakes, and tsunamis often occur along these plate boundaries, though tsunamis can also occur at places distant from the source earthquake locations. Tsunami are actually waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, major volcanic eruptions or large meteorite impacts. How do tsunamis occur? There is evidence that the Australian coast may have experienced large tsunami during the past few thousand years.

Tsunamis are hallmarked by permanent large vertical displacements of very large volumes of water which do not occur in explosions.
Tsunamis occur in coastal areas and are particularly common in areas with high seismic activity. Where do Tsunamis Happen? Tsunamis can happen in any significant body of water but are most common in the Pacific Ocean, where there are loads of underwater earthquakes and volcanoes. HOW TSUNAMIS OCCUR 1 As one plate subducts below another, pressure builds after many years, resulting in a section of the mega-thrust giving away 2 As this section gives way, it ruptures the ocean floor, resulting in a massive displacement of water, causing a … As the first cause is the most frequent we will focus on it. Generally the danger of a tsunami occurring exists where earth- and lake-quakes are possible, in areas where tectonic plates collide with each other, drift past each other or collide, as well as in other areas with geological faults.
