Strain Rates Along the Alpine‐Himalayan Belt From a Comprehensive GNSS Velocity Field

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine‐Himalayan belt is one of Earth's most dynamic and complex regions, characterized by intense tectonic deformation and seismicity. Comprehensive analyses of continental‐scale crustal deformation and seismic hazards along this extensive orogenic belt require the compilation of large geodetic data sets.

Imaging the Shallow Structure Beneath Askja Volcano, Iceland, With Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Askja is a large central volcano in the Northern Volcanic Zone (NVZ) of Iceland which last erupted effusively in 1961 and subsequently experienced steady deflation from the 1970s until August 2021, when GPS and InSAR measurements confirmed that it had begun re‐inflating.

Temporal stability of soil moisture and radar backscatter observed by the advanced Synthetic Aperture Radar (ASAR) [PDF]

, 2008
The high spatio-temporal variability of soil moisture is the result of atmospheric forcing and redistribution processes related to terrain, soil, and vegetation characteristics.

Magma Ascent and Accumulation Drives Surface Deformation and Ring Fault Seismicity Preceding the 2024 Eruption of Fernandina Volcano, Galápagos Islands

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract At caldera volcanoes, ring faults can play a key role in controlling the dynamics of unrest and patterns of associated surface deformation and seismicity. Here we show that the March 2024 eruption of Fernandina volcano was preceded by a 2.5‐year episode of magma accumulation, driving surface uplift and asymmetric seismicity on a ring fault ...
