Seismology
Aseismic
Earth science; Seismology
Not associated with an earthquake, as in aseismic slip. Also used to indicate an area with no record of earthquakes: an aseismic zone.
Flower structure
Earth science; Seismology
More-or-less symmetrical splays into sub-faults near the intersection of the main fault with the ground surface.
Surface waves of earthquakes
Earth science; Seismology
Seismic waves that follow the Earth's surface only, with a speed less than that of S-waves. There are two types of surface waves - Rayleigh and Love waves.
Transverse
Earth science; Seismology
Seismic waves that arrive entirely horizontal to the great-circle path direction.
Radial
Earth science; Seismology
Seismic waves arriving at a station propagating at some angle to the vertical along the great-circle path connecting the source and receiver.
Love waves
Earth science; Seismology
Seismic surface waves with only horizontal shear motion transverse to the direction of propagation.
Rayleigh waves
Earth science; Seismology
Seismic surface waves with ground motion only in the vertical plane containing the direction of propagation of the wave. The particle motion is retrograde elliptical at the surface grading into ...
