High Resolution Focal Mechanisms and Stress Field Orientation in Southern Italy From Short‐Term Dense Arrays

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Understanding fault geometry and mechanics is key to interpreting the seismotectonic setting of a region. We analyze data from a 1‐year dense seismic array deployment in Southern Italy to infer focal mechanisms and stress field from low‐magnitude earthquakes using machine‐learning techniques.

A New Amphibious Earthquake Catalog for the Alaska Peninsula: Training, Testing, and Applying Machine Learning Earthquake Picking in Offshore and Amphibious Environments

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract The dual seismological developments of large‐scale offshore observational networks and high‐quality machine‐learning earthquake detection and picking allow unprecedented seismicity detection in high hazard subduction zones. We develop a high resolution machine learning enhanced seismicity catalog for the Alaska Peninsula stretch of the Alaska ...

Mechanical Decoupling Across the Deep Megathrust Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract We examine stress and strength across the deep subduction plate boundary at ∼60 km depth offshore northeastern Japan, near the downdip seismic limit of the megathrust. High‐frequency (2–5 Hz) moment tensor inversion of ∼2,000 M 2–3.5 earthquakes, integrated with existing catalogs, increases the number of focal mechanisms by more than a factor ...

Revealing the Hydrothermal System of La Soufrière Volcano (Guadeloupe) Through Nodal Ambient Noise Tomography

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract La Soufri'ere de Guadeloupe is an active volcano of the Lesser Antilles Volcanic Arc. Its last eruption halted in 1977, yet hydrothermal activity has increased over recent years, raising summit instability hazards. The link between hydrothermal fluids and detachment landslide surfaces is well established and exacerbated by inflation ...
