(S) waves have a side-to-side type of vibration. Both P and S waves travel deep into the Earth, reflecting off the surfaces of its various layers. S waves cannot travel through the liquid outer core. By contrast, surface (L) waves—a third type of wave, named after the 19th-century...
We present the 3D seismic model of crustal structure and the distribution of seismicity in the El Asnam region ( Algeria ) where a strong earthquake (M7.3) occurred in 1980. We apply the local earthquake tomography inversion for the data of temporary networks which recorded the aftershocks of ...
Earthquake - Seismic Waves, Faulting, Ground Shaking: Earthquakes often cause dramatic geomorphological changes, including ground movements—either vertical or horizontal—along geologic fault traces; rising, dropping, and tilting of the ground surface;
Waveform similarity in an earthquake swarm enables precise arrival time differences of P- and S-waves through cross spectral methods to be obtained. A numerical simulation guarantees the time resolution of the order of 1 ms for the time differences. This precise arrival time difference is used to...

Body waves: Waves which propagate through the interior of a body. For the Earth, there are two types of seismic body waves: (1) compressional or longitudinal (Pwave), and (2) shear or transverse (Swave). Coda waves: Waves which are recorded on aseismogram(q.v.) after the passage of...
We present a dynamic rupture model of the 2016 Mw 7.8 Kaikōura earthquake to unravel the event’s riddles in a physics-based manner and provide insight on the mechanical viability of competing hypotheses proposed to explain them. Our model reproduces key characteristics of the event and constraint...
An important research technique is to infer the character of faulting in an earthquake from the recorded seismograms. For example, observed distributions of the directions of the first onsets in waves arriving at the Earth’s surface have been effectively used. Onsets are called “compressional” or...
