Stochastic inversion method based on compressed sensing frequency division waveform indication prior
Frontiers in Earth ScienceThe stochastic inversion method using logging data as conditional data and seismic data as constraint data has a higher vertical resolution than the conventional deterministic inversion method.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The mantle transition zone (MTZ; ∼410–660 km depth) is a major reservoir of water and mid‐ocean ridge basalt (MORB)‐like materials, yet how composition and hydration regulate its physical stability remains unclear. Using geodynamical modeling, we examine the joint effect of water content and dense MORB fraction on the density, viscosity, and ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

Segmented Moho Uplift and Implications for Magmatic Underplating Beneath the Datong Basin
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Understanding how the deep crust responds to coupled tectonic and magmatic processes is essential for deciphering intracontinental rifting. We apply high‐resolution passive‐source reverse time migration to teleseismic P‐wave receiver functions recorded by a dense seismic array to image the Moho beneath the Datong Basin. Our observations reveal

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract We present new results from ambient noise tomography and azimuthal anisotropy analysis of the DOMERAPI data set to investigate crustal structure beneath the Merapi‐Merbabu‐Telomoyo region in central Java. The 3D shear‐wave velocity (Vs) model reveals a prominent high‐Vs anomaly extending from south of Merapi through Merbabu to Telomoyo ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The mechanisms underlying the patchy distribution of forearc megathrust earthquakes and arc volcanoes in subduction zones remain poorly understood. Here we present a high‐resolution seismic tomographic model of the Central American subduction zone, derived from a joint inversion of local body‐wave and teleseismic Rayleigh‐wave data.

Energy GeoscienceSeismic exploration is the most precise geophysical method for investigating and forecasting subsurface resources, yet its conventional fully elastic assumption neglects temperature effects, limiting its utility in geothermal studies.
