Term Definition
transform boundaries moderate and shallow earthquakes occur here
convergent boundaries strong and deep earthquakes occur here
divergent boundaries weak and shallow earthquakes occur here
P-waves move back and forth; fastest; can travel through all material
S-waves move like a snake; second to arrive; cannot go through liquid mass
surface waves move ground up and down in circles; slowest; most destructive; feels like a roller coaster
elastic rebound this causes earthquakes; the ground suddenly retains original shape
epicenter the ground directly above where the earthquake occured
focus the direct area of seismic activity
moho seismic waves travel much faster upon reaching this area
shadow zone area where no direct seismic waves can be detected
seismograph an instrument that records seismic waves
seismogram a recording of the shaking motion in earthquakes
seismic gap a particular area along a seismic-active location where unusually few earthquakes have occured
gap hypothesis the theory that areas where few earthquakes have occured are likely to experience aerious quakes in the future
seismology the study of earthquakes
sunquakes caused by solar flares; much stronger than our earthquakes
moonquakes seismic waves last much longer than they do on Earth
marsquakes some earthquakes, though seismographs often acted more like a wind gauge because of the wind
mass damper a weight in the building roof that will counteract w/ building movement when activated
active tendon system a weight in the building's base, similar to the mass damper
base isolators these are in the base of the building; made of rubber w/ a lead core; absorb seismic waves to avert their travel through the building
cross braces steel braces in between the floors that support the building during earthquakes
body waves seismic waves that travel through the Earth's interior
surface waves seismic waves that travel along the Earth's surface
time-distance graph compares the distance between P waves and S waves
S-P time method the common method used to find an earthquake's epicenter
Ritcher scale tool used for measuring earthquake strength
31.7 the number of times greater energy an earthquake w/ one # greater magnitude releases than the lower
earthquake hazard measures how vulnerable an area is to future earthquakes
