Tsunamis in the United States
In a total of 74 tidal waves classified as a tsunami since 1737 a total of 548 people died in the United States. Tsunamis therefore occur comparatively often in this country.The strongest tidal wave registered in the United States so far reached a height of 524.26 meters. At this Tsunami on 07/10/1958 a total of 5 people have been killed.
The biggest impact in terms of lifes, injuries, destroyed homes and economy had been a tsunami on 04/01/1946. A tidal wave of up to 42.20 meters killed 164 humans and destroyed vast areas.

Tsunamis are caused by earthquakes or other seismic eruptions on ground of an oceans and can cause massive tidal waves, which run with enormous force on land, causing great devastation. Especially in regions with only few tsunamis, the damage is often drastic, as the population does not expect tsunamis and thus hardly takes any protective measures. Even relatively small flood waves can lead to high losses and financial damage.The marked positions on the map represent the most effected regions within the past 240 years.
