Characterizing the Forearc Basement and Subducting Structures of the Northern Ecuadorian Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present 2D P‐wave velocity (Vp) models from the northern Ecuadorian subduction zone, north of the Carnegie Ridge. Data were collected during the HIPER2 3D wide‐angle seismic experiment, both onshore and offshore. Key seismic profiles were manually picked to determine P‐wave first‐arrival times, which were used for a traveltime tomographic ...

Building the Andean Crust at ∼35°S: Arc Geochemistry Reveals Cretaceous Thinning and Rapid Neogene Thickening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Quantification of the timing and mechanisms of crustal thickening in Cordilleran orogenic hinterlands remains challenging. We address this in the Andes using whole‐rock geochemistry and zircon petrochronology from a >70 Myr volcanic record in the Tinguiririca valley of Chile (∼35° ${}^{\circ}$S), which captures a pivotal transition from ...

Implications of Thermal Weakening and Magma Compressibility for Volcano Monitoring

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Magmatic intrusion and volcanic deformation are traditionally approximated with an inflating cavity in an elastic halfspace. Various analytical models predict surface displacement as a function of pressure or volume change, depth, and elastic crustal properties.

Testing the Seismic Detectability of Magmatic Underplating Beneath the Hawaiian Ridge: A Synthetic Wavefield Approach

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Magmatic underplating beneath the Hawaiian Ridge has been inferred from early active‐source and teleseismic studies, whereas more recent active‐source seismic imaging and reprocessed legacy data have not identified a distinct underplated layer.

A Likelihood‐Free Framework for Seismic Forecasting Models: Application to Incomplete ETAS Model via Simulation‐Based Inference

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Recent advances in deep‐learning‐based earthquake detection have revolutionized seismology, producing high‐resolution catalogs complete down to very low magnitudes. While these data sets offer an unprecedented view of seismic triggering, their massive scale and inherent short‐term incompleteness pose a major challenge for traditional ...
