Different types of earthquakes are based on the movement along the fault line. In a normal fault, one side of the fault line moves up and one side moves down. A reverse quake the one side moves down and one side moves up. In a strike-slip earthquake, the movement is horizontal. If the movement on the far side of the fault line moves to the left it is called a left-lateral. If the far side of the fault line moves to the right it is called a right-lateral. There is one more kind of earthquake. The oblique-slip moves horizontal and up and down.

When the rock breaks it creates vibrations. These vibrations are called seismic waves.Two types of seismic waves are body waves and surface waves.
Body waves have two kinds:
Compression-(Primary Waves) the fastest wave-
push and pull the rock-can
travel through solids, liquids, and gases
Shear -(Secondary Waves) slower-move from side to
side-can only pass through solids
Earthquakes are based on theses factors:
- Magnitude
- Type
- Depth
- Distance from epicenter
- Soil Conditions
- Preparedness of population
- Time of day
- Duration
Surface waves have two kinds
Long waves-travel horizontally and move the
ground side to side and are long and slow.
Rayleigh waves-make the ground roll like
waves in the ocean.
