Earthquakes
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves.

Focus
the center of interest or activity.
Epicenter
The epicenter or epicentre is the point on the Earth's surface that is directly above the hypocenter or focus, the point where an earthquake or underground explosion originates.
Seismology
Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.
Seismograph
Seismometers are instruments that measure motions of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources.
Magnitude
the great size or extent of something
Intensity
the measurable amount of a property, such as force, brightness, or a magnetic field.
Tsunami
A Tsunami is when a whole bunch of water or wave goes in land.
Seismic Gap
Three seismic gaps are seen, where the density of earthquakes appears to be lower than along sections of the fault outside the gaps.
