Why is there a tsunami at sea?

Sometimes, there is no storm at sea, but the waves roll for a while, and the waves as high as several meters rush to the coast, which is very serious. This is what people often call a "tsunami".

So, why is there a tsunami at sea?

The main reason is the submarine crust fracture.

Some places sink, while others rise, causing the earth's crust to shake violently, resulting in huge waves with extremely long wavelengths. These huge waves rush to the coast or harbor, causing the water level to skyrocket and rush to the land, which is extremely destructive.

The eruption of submarine volcano is another cause of tsunami.

Volcanoes erupting underwater will also cause seawater to boil and the water column to skyrocket, killing a large number of fish and marine life, causing biological corpses to spread all over the sea.

In addition, the material on the submarine slope sometimes loses its balance, which leads to submarine landslide and tsunami.

Some tsunamis are also caused by wind. The powerful typhoon crossed the sea surface, which caused the water level on the shore to surge and even flooded the sea, causing great losses to mankind. People call this phenomenon "storm tsunami" and "meteorological tsunami".
