We just learned about the Supershear Earthquake.
Another type of earthquake is a Tsunami Earthquake.
This is an earthquake that happens underwater that may not be very big, but it causes a very big tsunami.
It can be dangerous because scientists might not be able to tell a big earthquake happened, and a tsunami might come by surprise.
