New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...

Lithospheric Rheology in Southern California Derived From Novel Observations of Lake Unloading

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Recent Lake Cahuilla has undergone repeated filling and drying cycles over the past millennium, resulting in lithospheric and mantle loading responses. Two critical but less well‐constrained factors influencing these responses are the elastic plate thickness and mantle relaxation time.

Teleseismic S‐Wave Coda Autocorrelation and vp/vs ${v}_{p}/{v}_{s}$ Distribution Over the Antarctic Ice Sheet

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate characterization of the compressional to shear (P‐to‐S) wave‐speed ratio (vp/vs ${v}_{p}/{v}_{s}$) within the Antarctic Ice Sheet (AIS) is crucial for understanding its internal structure, mechanical stability, and vulnerability to a changing climate.

Thermochemical Controls on the X, 410, and 660 Discontinuities in the Central Mediterranean

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The mantle beneath the Central Mediterranean is thermally and compositionally heterogeneous, as indicated by fragmented and locally stagnant slabs in tomographic images and HIMU‐like anorogenic magmatism. Mantle discontinuities are sensitive to both temperature and composition, and thus provide a way to quantify these heterogeneities.

Multi‐Scale Spatial Variations in Pacific Mantle Seismic Anisotropy: Constraints on Plate Evolution and Asthenospheric Flow

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We present array‐scale (∼500 × 500 km) anisotropic shear‐velocity models from two Pacific ocean‐bottom seismometer (OBS) arrays of the OBS Research in the Convecting Asthenosphere (ORCA) experiment: Young ORCA (∼43 Ma) and Old ORCA (∼90 Ma). Rayleigh‐wave phase velocities spanning 5–150 s are combined with Love‐wave phase velocities from 5 to ...
