• Fault

It occurs when rock layers in the crust are squeezed together.

• Normal Fault

• Strike-slip Fault

• Reverse fault

It is the starting point of the earthquake.

It occurs when two forces pushes the object on two opposite sides.

• Tensional stress

• Compressional stress

• Shearing stress

It is the one who studies the earthquakes and its related phenomena.

A device that can detect and record seismic waves.

It describes the energy released by an earthquake.
