Full Waveform Inversion (FWI) is capable of finely characterizing the velocity structure, anisotropy, viscoelasticity, and attenuation properties of subsurface media, which provides critical ...

In the process, they also showed that seismic waves travel much deeper on Mars than expected, posing new questions about the Red Planet’s geology. On Earth, most earthquakes result from plate ...

The technique focused on analyzing the SKKKP seismic core phase—a specific pattern of wave propagation and reflection at the CMB. By conducting an in-depth analysis of SKKKP waves, researchers ...

Particles subjected to a P wave move in the same direction that the wave is moves in; it is the direction that the energy is traveling in, sometimes called the “direction of wave propagation.” ...

We also have a very strong program in computational geophysics, with three new faculty that perform large-scale parallel computations to constrain seismic-wave propagation and hydrologic flow. Geology ...

wave propagation studies and determination of lithospheric structure. Since 1981 I have supervised the operations of the New England Seismic Network of Weston Observatory of Boston College, which ...

which uses "electrical energy . . . as a wave source" that "monitor[s] seismic wave energy" on dry, wet, and frozen diabase samples. Experimentation revealed that the seismic velocities of the dry ...

A new analysis of earthquake rupture directivity provides essential insights for seismic hazard and risk assessments in urban ...
