Earthquake: An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves.
Elastic Rebound:The elastic rebound is an explanation for how energy is spread during earthquakes. As rocks on opposite sides of a fault are subjected to force and shift
focus: the point beneath the earth's surface at which an earthquake or underground nuclear explosion originates.
Epicenter:The epicenter or epicenter 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.
Seimology: 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:Magnitude may refer to: In mathematics: Magnitude, the relative size of an object; Magnitude , a term for the size or length of a vector
Intensity: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
Tsunami:A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake.
Seismic Gap:A seismic gap is a segment of an active fault known to produce significant earthquakes, that has not slipped in an unusually long time
