Earthquakes
Anatomy of an earthquake
Focus (Hypocenter)
The focus, also known as the hypocenter, is the center of the earthquake. It can also be described as the point where the seismic waves originate from. It is located beneath the earth's surface.
Epicenter
The epicenter is the point on the surface of the earth, directly above the focus. It is where the seismic waves are most intense.
Faults
Faults are fractures between the tectonic plates. The energy stored in faults are what causes earthquakes.
Tectonic plates
Plates are large masses of rock in the earth's lithosphere. The collision of these plates create tension which is stored in faults.

Faults
Description
Faults are the boundaries between tectonic plates, wherein the energy from colliding against each other is stored.
Types of Faults
Normal Fault
Normal faults cause the land above the fault [hanging Wall] to sink relative to the land below the fault [foot Wall].
Reverse (Thrust) Fault
Reverse faults cause the land above the fault [hanging Wall] to rise relative to the land below the fault [foot Wall].
Strike-slip fault
Strike-slip faults cause the land to move opposite each other while being parallel to the earth's surface.

Description
Earthquakes are weak to violent shaking of the ground caused by the sudden movement of rock beneath the earth's surface. It is nature's way to release tension between two tectonic plates that have collided with each other.
