Most of the world’s earthquakes, tsunamis, landslides, and volcanic eruptions are caused by the continuous motions of the many tectonic plates that make up the Earth’s outer shell. WebJan 11, 2024 · Other events that can generate tsunamis include asteroids crashing into the ocean. When a tsunami is triggered under the sea, it causes a rapid and massive displacement of seawater. The water lying above the disturbed point can uplift water on the surface and build up speeds that can reach about 500 miles per hour.
