It can cause tsunamis.
tsunamis and tidal waves are some of the effects
They happen along the fault lines that separate or crash into each other. The planet is made of Tectonic plates that are constantly moving, and that's why earthquakes happen
When a lot of earthquakes happen in a short time, it's called a swarm.
This is known as an aftershock.
Undersea earthquakes can cause tsunamis, not the other way round. It is the sudden movement of the crust under the ocean which can trigger a tsunami.
tsunamis and tidal waves are some of the effects
Earthquakes happen under the sea sometimes. This will have the effect of shaking the sea. If you have a bowl of water and shake it, you will get waves in the bowl. That is what happens when an earthquake occurs under the sea and why we get tsunamis caused by earthquakes.
If there is an earthquake under the sea, you might die, if you are on a ship.
The Pacific Ocean.
An Earthquake occurs.
Earthquakes happen because the plates of the earth move. If a plate moves and a country is near it it will cause an earthquake, but if it happens in the sea it can cause a tsunami.
tsunami
it depends, it could break or have nothing happen depending on the strength
this would cause a tsunami
If the earthquake occurs on land - the highest damage occurs at the epicentre (the point at which the quake starts). If the quake begins at sea - most damage is caused at coastal regions from tidal waves.
tsunamis usually occurs after an earthquake specially under sea earthquakes.
A tsunami is only created when an earthquake or giant land slide occurs under the sea. The Christchurch earthquake happened at an inland site away from the ocean.
