Comment to Shreve and Delgado (2023)—“Trapdoor Fault Activation: A Step Toward Caldera Collapse at Sierra Negra, Galapagos, Ecuador”

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract In their article entitled “Trapdoor Fault Activation: A Step Toward Caldera Collapse at Sierra Negra, Galapagos, Ecuador” Shreve and Delgado (2023, https://doi.org/10.1029/2023jb026437) examine co‐eruptive deformation during the 2018 eruption of Sierra Negra Volcano. One of their major conclusions is that the 2018 eruption, and specifically co‐

3D Dynamic Rupture Modeling of the 2021 Haiti Earthquake Used to Constrain Stress Conditions and Fault System Complexity

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract The 2021 Mw ${M}_{w}$7.2 Haiti earthquake was a devastating event which occurred within the Enriquillo Plantain Garden Fault Zone (EPGFZ). It is not well‐understood why neither the 2021 nor the prior 2010 Mw ${M}_{w}$7.0 earthquakes were pure strike slip events and, instead, ruptured with distinct patches of dip slip and strike slip motion on ...

Rupture of the 1949 Khait Earthquake on a Cryptic Fault: Implications for Earthquake Hazard

Tectonics, Volume 44, Issue 10, October 2025.
Abstract The 1949 Mw 7.6 Khait earthquake, Tajikistan, was one of the most destructive of the Pamir—Tien Shan region, killing over 7,000 people by building collapse and landsliding. It occurred at the transition between the Pamir and Tien Shan mountain ranges, which converge along the narrow Vashkh river valley.

Simultaneous Classification and Location of Volcanic Deformation in SAR Interferograms Using a Convolutional Neural Network

Earth and Space Science
With the evolution of interferometric synthetic aperture radar into a tool for active hazard monitoring, new methods are sought to quickly and automatically interpret the large number of interferograms that are created.

Spatiotemporal Variations of Terrestrial Water Storage and Driving Factors in the Water Towers of Northwest China Based on GRACE and Multi‐Source Data Sets

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Mountains represent important water towers and thus are the primary water suppliers for downstream areas. However, divergent trends in terrestrial water storage (TWS) in water towers and their driving factors have not been clarified. This study investigated water tower units (WTUs) in Northwest China (NWC) and used GRACE/GRACE‐FO and multi ...

Extrapolation of Airborne Polarimetric and Interferometric SAR Data for Validation of Bio-Geo-Retrieval Algorithms for Future Spaceborne SAR Missions [PDF]

, 2009
Spaceborne SAR system concepts and mission design is often based on algorithms developed and the experience gathered from airborne SAR experiments and associated dedicated campaigns. However, airborne SAR systems have better performance parameters than

Total variation regularization for manifold-valued data

, 2013
We consider total variation minimization for manifold valued data. We propose a cyclic proximal point algorithm and a parallel proximal point algorithm to minimize TV functionals with $\ell^p$-type data terms in the manifold case.

Volcano‐Tectonic Crisis of Mayotte (2018–2022): A Deformation Model for Geodetic Applications

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Volcano‐tectonic unrest during the 2018–2022 crisis of Mayotte (Comoros archipelago) generated an island‐wide surface displacement reaching ∼ ${\sim} $20 cm, with a relative (internal) deformation of the island of ∼ ${\sim} $10 cm. Correcting for these displacements, which exceed the required accuracy of geodetic network reference coordinates,
