normal fault
origin of the earthquake inside of the eart
focus or hypocenter

epicenter
movement of rocks vertically
dip slip fault
results from tension
normal fault
results from compression
reverse fault
movements of rocks horizontally
strike slip
instrument that detects and records waves produced by earthquakes
seismograph
measured energy released by an earthquake
magnitude
earthquake with highest magnitude
mainshock
