Submarine Flank Collapses at Tagoro Volcano: Insights From Bathymetric Surveys and 3D Multiphase Simulations

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.

Surrogate‐Assisted Bayesian Inference of Fracture Network Parameters From Elastic Waves: A Sensitivity‐Guided Approach

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We develop a sensitivity‐guided, surrogate‐assisted Bayesian framework to infer fracture network parameters from elastic waves. Synthetic fracture networks characterized by power‐law length exponent a $a$, fracture density d $d$, and percolation parameter p $p$ are constructed.

Uplift of the Transantarctic Mountains: Evidence for an Evolving and Long‐Lived Rayleigh‐Taylor Instability

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Rayleigh‐Taylor instabilities within the upper mantle are investigated as a mechanism for the uplift of rift‐margin mountain ranges within the continents. Our focus is on the Transantarctic Mountains (TAM). These mountains form at the margin between East and West Antarctica and have been free from the effects of subduction for about 500 ...

Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

Inversion by Intrusion: Magma‐Driven Shortening in the Turkana Rift (East Africa)

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract Late Pliocene to Pleistocene inversion in the Turkana Rift, observed on seismic reflection data and in outcrop, presents a tectonic paradox by indicating local shortening in an overall extensional setting. Previous studies attributed this inversion either to the reactivation of obliquely oriented structural weaknesses or to reorientation of ...

Spatial Dependence of High‐Frequency Ground Motion Along the Chilean Subduction Zone From Aftershock Sequences of the Mw 8.8 Maule and Mw 8.2 Iquique Earthquakes

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract The Chilean subduction zone is a highly active seismic region, producing megathrust earthquakes approximately every decade. We apply a stochastic approach to assess spatial variations in seismic wave characteristics along the Chilean trench using weak motion data.

Kamafugite Magma Pathways and Lava‐Flow Paleotopography From Three‐Dimensional Audiomagnetotelluric Imaging Constrained by Borehole Data

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract An audiomagnetotelluric (AMT) survey was conducted within the Alto Paranaíba Igneous Province, southeastern Brazil, to delineate shallow occurrences of kamafugite, a rare ultrapotassic volcanic rock worldwide. A dense grid of AMT stations was deployed, allowing the construction of a high‐resolution 3D electrical resistivity model ...

A Statewide InSAR Velocity Map for California Produced by a Comprehensive Large Scale Analysis of ARIA Standard Products

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Routine Synthetic Aperture Radar (SAR) acquisitions from the Sentinel‐1 constellation enable monitoring of slow surface deformation (millimeters to centimeters per year), yet consistent and accessible pathways for producing validated, user‐ready velocity products remain limited.
