Earthquakes
Anatomy of an earthquake
Epicenter
Is where the earthquake is most intensely felt. This is located directly above the focus or the hypocenter.
Focus
This is where the initial vibration originates. It is usually underground and the waves come up to the surface.
Faults
Is where two tectonic plates meet. Some faults are considered active because they are very vulnerable to slipping or causing an earthquake
3 types of faults
Reverse Fault
Is a fault where if it were to slip, the hanging wall will move upwards relative to the footwall. There is also compression found along this fault.
Strike-Slip Fault
Is a vertical or almost vertical fault. When this fault slips, it moves sideways, or left and right. There are two kinds of Strike Slip faults

Normal Fault
Is a fault where if it were to slip, the part known as a footwall will move upwards relative to the hanging wall. There is also tension found along this fault.
An earthquake is an event where two tectonic plates slip along a fault. When earthquakes happen, a vibration is usually felt.
Earthquake strength
Earthquake strength is measured via seismograph on the focus or somewhere in the radius of the earthquake.
