surface along which rocks move when they passs their elastic limit and break fault
vibrations produced when rocks break along a fualt earthquake
break ion rock caused by tension forces, where rock above the fault surface moves down relative to the rock below the fault surface normal fault
break in rock caused by compressive forces, where rock above the fault surfaces move upward rocks relative to the rock bleow the fault surface reverse fault
break in rock caused by shear forces, where rocks move past each other without much vertical movement strike-slip fault
rhythmic omvemenmt that carries energy though matter and space wave
wave genersted by an earthquake seismic wave
in an earthquake, the point below Earths surface where energy is released in the form of seismic waves focus
seismic wave that moves rock particles back-and-forth in the sane direction that the wave travels primary wave
seismic wave that moves rocks particles at rigth angles to the direction of the wave secondary wave
seismic waves that moves rock particles up-and-down in backward rolling motion and side-to-side ina swaying motion surface wave
point on Earths surface directly above an earthquakes focus epicenter
instrument used to register earthquake waves and record the time that each arrived seismograph
