Researchers presented the results of efforts to perform global full waveform inversions of the Earth using the Frontera supercomputer. They used data from 300 earthquakes to construct the new global ...

Full-waveform inversion (FWI) has emerged as a transformative method in seismic imaging, employing the entire recorded seismogram to iteratively reconstruct detailed subsurface models. By leveraging ...

According to WesternGeco's Houston-based research director, recent advances in processing capabilities are allowing sophisticated seismic data migration methods to become standard practice. According ...

In modern Earth science research, how to “understand” the Earth’s internal structure and dynamic processes has always been a core issue of concern for scientists. However, due to the inaccessibility ...

Earthquakes do more than buckle streets and topple buildings. Seismic waves generated by earthquakes pass through the Earth, acting like a giant MRI machine and providing clues to what lies inside the ...

Azimuthal anisotropy (black dashed lines showing the fast direction of wave speeds) in the mantle at 200 km depth plotted on top of vertically polarized shear wave speed perturbations (dVsv) after 20 ...
