In order for an underwater earthquake to generate a tsunami, it must be a large and it must cause vertical shifting of the sea floor.

Some under or near water earthquakes will fail to produce a tsunami because they are not strong enough or only cause horizontal shifting.

What are tornadoes hurricanes tsunamis earthquakes?

Tornadoes are violent rotating columns of air that form during severe thunderstorms. Hurricanes are large storms that form over warm ocean waters and have strong winds and heavy rain. Tsunamis are powerful ocean waves caused by underwater earthquakes or volcanic eruptions. Earthquakes are sudden, rapid shaking of the ground caused by the shifting of tectonic plates beneath the Earth's surface.

Can you have earthquakes under water?

Yes, earthquakes can occur underwater, causing what is known as a tsunami. These underwater earthquakes are typically caused by the shifting of tectonic plates beneath the ocean floor. The resulting seismic waves can generate powerful underwater disturbances that propagate to the surface.
