An earthquake is the result of a sudden release of energy in the Earth's
crust that creates seismic waves.
crust that creates seismic waves.
The elastic rebound theory is an explanation for 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.

Seismology is the scientific study of earthquakes and the propagation of
elastic waves through the Earth or through other planet-like bodies

Seismometers are instruments that measure motions of the ground, including
those of seismic waves generated by earthquakes, volcanic eruptions, and other
seismic sources.

Magnitude is the logarithmic measure of the brightness of an object, in
astronomy, measured in a specific wavelength or passband, usually in optical or
near-infrared wavelengths.

In physics, intensity is the power transferred per unit area. In the SI
system, it has units watts per metre squared. It is used most frequently with
waves, in which case the average power transfer over one period of the wave is
used.

a long high sea wave caused by an earthquake, submarine landslide, or other disturbance.
A seismic gap is a segment of an active fault known to produce significant earthquakes, that has not slipped in an unusually long time when compared with other segments along the same structure.
