An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves.
The elastic rebound tells you how energy is spread during earthquakes. As rocks on opposite sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their internal strength is exceeded.
The focus of an earthquake is the point beneath Earth's surface where rock breaks under stress and the plates shift and that is what causes the earthquake

Seismology is the study of earthquakes and seismic waves that move through and around the earth.
Magnitude is a measure of the amount of energy released during an earthquake. It may be expressed using several magnitude scales
The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth's surface and on humans and their structures.
Tsunamis occur because of volcanic eruption, landslides or other movements of the Earth's surface.
A seismic gap is a section of a fault that has produced earthquakes in the past but is now quiet.
