Seismometer
200
Point on Earth's surface directly above an earthquakes starting point
Epicenter
200
The BODY wave that:
-moves the fastest
-move with a push-pull motion

Scale used by scientists to measure earthquake energy/strength (amplitude/height)
Richter Scale
300
Any fracture/break along which the ground moves
Fault
300

S Waves
300
Method used by scientists at earthquake stations to pinpoint the location of the epicenter.

-building foundations that can move up and down or side to side
-large weights on bridges
