Earthquakes

Earthquake is very dangerous in earth. I'm a seismologist that studies earthquake.I know earthquakes are usually caused when the rock underground suddenly breaks along a fault.There is a release energy that causes the seismic waves to make the ground shake.An earthquake happens when two blocks of earth suddenly slip past one another.Earth has four major layers and they are inner core,outer core,mantle, and crust.Each layer is made up with many faults.Some facts I know is that when an earthquake occurs the safe way you can protect yourself is by hiding under a table.The place you should avoid near by is windows,large mirrors,hanging objects,heavy furniture and fireplaces. As it said many earthquakes happens at the edge of the oceanic continental plate.I'm studying the danger of earthquake.
