UNDER WATER EARTHQUAKES:
Sometimes they are harmless, no more than small waves. But other times the can cause tsunamis or giant cracks under the sea. Under water earthquakes are often happening.
They are caused when an underground earthquake comes to the surface which happens to be underwater. And other times there is just a earthquake that occurs under the sea.
I have placed some diagrams to show you what they do and how they are caused.
I hope they are useful.
