Seismology
phase velocity
Earth science; Seismology
The velocity of each harmonic component of the surface wave period that depends on the medium parameters such as layer thickness and P and/or S wave velocities. To get good estimates of phase ...
depth of an earthquake
Earth science; Seismology
The value given is the depth below the surface of the mean spheroid.
hertz
Earth science; Seismology
The unit of frequency equal to 1 cycle per second, or 2 PI radians per second.
S wave
Earth science; Seismology
The secondary seismic wave, traveling more slowly than the P wave and consisting of elastic vibrations transverse to the direction of travel. It cannot propagate in a liquid (e.g. outer core).
seismometer
Earth science; Seismology
The sensor part of the seismograph, usually a suspended pendulum.
strong ground-motion
Earth science; Seismology
The shaking of the ground near an earthquake source made up of large amplitude seismic waves of various types.
oblique faulting
Earth science; Seismology
The slip on the fault has components both along the dip and along the strike of the fault.
