Question

How high can a tsunami be

Answer 1

Ответ:

In the area of ​​tsunami occurrence, the height reaches from 0.1 to 5 meters. When reaching shallow water, the wave height increases sharply, reaching a height of 10 to 50 meters.

Answer 2

A tsunami's height, also known as its run-up height or inundation height, can vary greatly depending on a variety of factors, including the magnitude of the earthquake or undersea landslide that triggers it, the depth and shape of the ocean floor, the distance from the source of the tsunami to the coastline, and local topography.

In general, tsunamis can reach heights of several meters (tens of feet) when they make landfall, but under certain circumstances, they can become significantly taller. The highest recorded tsunami wave, known as the 1958 Lituya Bay megatsunami, reached an astounding height of approximately 524 meters (1,720 feet). This exceptional height was due to the specific geological features of Lituya Bay in Alaska, where the wave was funneled into a narrow, steep-sided fjord, causing it to surge to such extraordinary heights.

It's important to note that such extreme heights are rare, and most tsunamis do not reach such heights. However, even smaller tsunamis can still cause significant damage and loss of life due to the immense volume of water they carry and their ability to inundate coastal areas.
