What is the wave height of a tsunami?
However, most tsunamis have less than 3 m wave height. It radiates in all directions from the point of origin and covers the entire ocean. It generally consists of a series of waves, with periods ranging from minutes to hours. These are the waves generated by tremors and not by earthquakes themselves.
What caused the tsunami of 2004?
The tsunami was generated by a large earthquake in the Southern Pacific Ocean. Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height.
How do scientists predict tsunamis?
[8] Scientists can accurately estimate the time when a tsunami will arrive almost anywhere around the world based on calculations using the depth of the water, distances from one place to another, and the time that the earthquake or other event occurred. [9]
