Earthquake

QuestionAnswer
earthquake Vibrations produced when rocks break along a fault.
epicenter Point on Earth's surface directly above an earthquake's focus.
fault Surface along which rocks move when they pass their elastic limit and break.
focus In an earthquake, the point below earth's surface where energy is released in the form of seismic waves.
liquefaction Occurs when wet soil acts more like a liquid during an earthquake.
magnitude Measure of the energy released during an earthquake.
normal fault Break in rock caused by tension forces, where rock above the fault surface moves down relative to the rock below the fault surface.
primary wave Seismic wave that moves rock particles back-and-forth in the same direction that the wave travels.
reverse fault Break in rock caused by compressive forces, where rock above the fault surface moves upward relative to the rock below the fault surface.
secondary wave Seismic wave that moves rock particles at right angles to the direction of the wave.
seismic wave Wave generated by an earthquake.
seismograph Instrument used to register earthquake waves and record the time that each arrived.
strike-slip fault Break in rock caused by shear forces, where rocks move past each other without much vertical movement.
surface wave Seismic wave that moves rock particles up-and-down in a backward rolling motion and side-to-side in a swaying motion.
