Answer:
a sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action.

A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake's waves.
