seismograph: An instrument that records and measures seismic waves
Richter scale: This scale is best for small nearby earthquake
stress: A force that acts on an area of rock to change it's shape or volume
plateau: A large area of flat land
liquefaction: This occurs when an earthquake's violent shaking turns loose soil into liquid mud
aftershock: An earthquake that occurs after another earthquake in the same area
focus: The area beneath Earth's surface where rock causes earthquakes
tsunami: The water displaced by an earthquake may form a large wave called a ?
friction: The force that opposes the motion of one surface as it moves across another
tension: This type of stress pulls on the crust
compression: This type of stress squeezes rock until it folds or breaks
shearing: This type of stress pushes a mass of rock in 2 opposite directions
Mercalli scale: Measures earthquakes according to their intensity and strength
earthquake: The shaking that results from the sudden movement of earth's surface
epicenter: The point on the surface directly above the focus
S wave: Seismic waves that vibrate from side to side and up and down
P wave: Seismic waves that compress and expand the ground like an accordion
magnitude: A number geologists assign to an earthquake
surface wave: Seismic waves that move slower than other waves
seismogram: The record of an earthquake's seismic waves produced by a seismograph
