This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when...
When natural disasters such as earthquakes or volcanic eruptions displace large amounts of ocean water, the result is a tsunami — an enormous wave that can reach speeds over 500 miles per hour in the open ocean. These waves threaten communities when they reach land.
Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. They speed along as fast as jet planes. As they near land, these waves rear up to great heights and can drown whole islands.
19 sty 2022 · But tsunamis are not normal waves, no matter the size. So how are tsunamis different from other ocean waves? What generates them? How do they travel so fast? And why are they so destructive?
The Grand Banks and Papua New Guinea tsunamis came from earthquakes which destabilised sediments, causing them to flow into the ocean and generate a tsunami. They dissipated before travelling transoceanic distances.
15 sie 2023 · Tsunamis are a series of long waves generated by a large and sudden displacement of the ocean. Large earthquakes below or near the ocean floor are the most common cause, but landslides, volcanic activity, certain types of weather, and meteorites can also cause a tsunami.
