| Question | Answer |
|---|---|
| the total force acting on crustal rocks per unit of area. | stress |
| the deformation of materials in response to stress. | strain |
| is caused when a materials is compressed, bent, or stretched. | elastic formation |
| when stress builds up past a certain point, called elastic limit. | plastic formation |
| the vibration of the ground produced during an earthquake. | seismic waves |
| squeeze and push rocks in the direction along which the waves are traveling. | primary waves |
| they are slower than p-waves, have a motion that causes rocks to at right angles in relation to the direction of the waves. | secondary waves |
| the point where the waves originate from | focus |
| the point on earth's surface directly above the focus. | epicenter |
| consists of a rotating drum covered with a sheet of paper, a pen or other such recording tool, and a mass, such as a pendulum. | seismometer |
| the record produced my a seismometer. | seismogram |
| a numerical rating system that measures the energy of the largest seismic waves. | richter scale |
| measure of the energy released during an earthquake. | magnitude |
| thee size of the seismic waves; and increase of 1 in the scale represents an increase in amplitude of a factor of 10. | amplitude |
| scale used to measure earthquakes magnitude-taking into account the size of the fault rupture, the rock's stiffness, and amount of movement along the fault-using values that can be estimated from the size of several types of seismic waves. | moment magnitude scale |
| measures earthquake intensity on a scale from 1 to XII; the higher the number, the greater the damage the earthquake has caused. | modified Mercall scale |
| seismic vibrations can cause the ground to behave like a liquid in a phenomenon. | soil liquefaction |
| a large ocean wave generated by vertical motions of the seafloor during an earthquake | tsunami |
| sections located along faults that are known to be active, but which have not experienced significant earthquakes for a long period of time. | seismic gap |
| any fracture or system of fractures along which Earth moves. | fault |
