Continental Magmatism and Dynamic Topography
… uplift is often expressed by positive long-wavelength gravity anomalies, radial drainage patterns, and slow seismic velocity anomalies within the upper mantle. Volcanic activity and elevated heat flow are also often observed. The aim of this study is to investigate the link between …

Seismic site characterization via joint modeling of horizontal-to-vertical spectral ratios and surface wave dispersion : developing and validating a geophysical tool for deciphering Quaternary stratigraphic architecture of the Monahans dune field, West Texas.
… Spectral Ratios (HVSR) and surface wave dispersion offer a cost-effective alternative to deciphering Quaternary architecture, but inverse models are subject to ambiguity and nonuniqueness. We jointly model HVSR and surface wave phase velocity dispersion measurements via global …

Ambient seismic noise tomography of the southern United States and seismic inversion with dictionary learning using unsupervised machine learning.
… which often deviate from simplified textbook models. High-resolution seismic tomography enables the interpretation of such intricate geological features. In the context of the Alleghenian orogeny, understanding Laurentia’s tectonic evolution depends on unraveling the structural relationships …

Enhanced imaging of deep lithospheric and shallow near surface structures through innovations in seismic interferometry and array processing.
… nodal array near Sweetwater, Texas to image P-wave reflectivity of the upper mantle. A coherent reflection event at approximately 26 seconds two-way time is detected consistently across eighteen linear sub-arrays and is interpreted as a PpP-type reflection response from a sharp, negative …
