earthquakes
An earthquake is the shaking of the ground caused by tectonic plates colliding. When the fault between plates break it occurs an earthquake.
Earthquakes are caused when two plates collide and when two plates finally release, they release energy which is causing the ground to vibrate.

Primary waves
Primary waves shake the ground back and forth. They are the fastest waves of all the waves that there are. Another way to say primary waves are to say P waves. P waves can cause rocks to change in volume. P waves also travel through solids, liquids. and gases. Think of P waves moving like a slinky when you shake it.
Secondary waves
Secondary waves are also called S waves. When S waves pass through rocks, it changes the rocks shape. They are the second fastest waves after the P wave. S waves can only pass through solids.
surface waves
The surface wave is the slowest waves of all of the types of waves. Although, they do cause the most damage. They are thrown sideways and forward at the same time. Surface waves can only travel along the surface.
Normal fault
One type of fault is a normal fault. A normal fault occurs where two blocks of rock are being pulled apart as by the tension. Most of the time normal faults are occcuring in places where the lithosphere is being pulled apart. They can also be found in deltas.
Reverse fault
Another type of fault id the reverse fault. Reverse faults occur where two blocks of rock are being forced together by compresion. They are exactly the opposite of normal faults.
strike-slip fault
The last type of fault is the strike-slip fault. A strike-slip fault is a fault in which surfaces on opposite sides of the fault plance has moved horozontaly and parallel to the strike of the fault.
Some questions:
What is a focus?
A focus is the point beneath earth's surface where rock breaks under stress and the plates shift.
What is an epicenter?
An epicenter is the point on the earth's surface directly above the focus.
What does a Richter Scale measure?
A Richter Scale measures the seismic energy released by earthquakes.
Who invented the Richter Scale and when was it invented?
The Richter Scale was invented by Charles Richter in 1935.
