equations of motion
Earth science; Seismology
The fundamental equations of seismology that relates the forces in the medium to measurable displacements. The equations include parameters such as density, body force per unit ...
corner frequency
Earth science; Seismology
The frequency at which the asymptotes to the low-frequency and high-frequency portion of the spectrum intersect. For the convolution of two boxcars, there will be two corner ...
Fmax
Earth science; Seismology
The frequency above which little seismic energy is observed at most strong-motion stations. This frequency cutoff may be produced by attenuation of shaking by unconsolidated ...
prediction of earthquakes
Earth science; Seismology
The forecasting in time, place, and magnitude of an earthquake; the forecasting of strong ground motion.
slab pull
Earth science; Seismology
The force of gravity causing the slab to sink into the mantle. The downdip component of this force leads to downdip extensional stress in the slab and may produce earthquakes ...
first arrival
Earth science; Seismology
The first recorded signal attributed to seismic wave travel from a source.
subduction thrust fault
Earth science; Seismology
The fault that accommodates the differential motion between the downgoing oceanic crustal plate and the continental plate as subduction occurs. This fault is the contact between ...
