Seismic signals generated by subsurface volcano‐tectonic processes commonly have low signal‐to‐noise ratios that make it difficult to resolve both 3‐D subsurface structures and seismic source locations using established seismic imaging methods (e.g ...

Seismic Structure of the Upper Mantle Beneath Eastern Asia From Full Waveform Seismic Tomography
To better understand the subsurface behavior of subducting slabs and their relation to the tectonic evolution of the overriding plate, we conduct a full waveform inversion on a large data set to determine a high‐resolution seismic model, FWEA18 (Full ...

Rôle of Digital Computers in Exploration Seismology [PDF]
In exploration, seismology surface sound sources and detectors are utilized to indicate variations in the elastic properties of the subsurface of the earth and from these infer the geological structure. It is helpful to pose the basic problem in a form that is common to most scientific investigations.

Using Deep Learning for Flexible and Scalable Earthquake Forecasting
Seismology is witnessing explosive growth in the diversity and scale of earthquake catalogs. A key motivation for this community effort is that more data should translate into better earthquake forecasts. Such improvements are yet to be seen.

A Python framework for efficient use of pre-computed Green's functions in seismological and other physical forward and inverse source problems [PDF]
The finite physical source problem is usually studied with the concept of volume and time integrals over Green's functions (GFs), representing delta-impulse solutions to the governing partial differential field equations.
