Stack #1211728

QuestionAnswer
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
