Widespread Extent of Irrecoverable Aquifer Depletion Revealed by Country‐Wide Analysis of Land Surface Subsidence Hazard in Iran

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Ongoing depletion of Iran's groundwater, driven by human extraction, has contributed to 106 incidences of basin‐scale, land‐surface subsidence covering 31,400 km2 (> ${ >} $10 mm/yr, 1.9%) of the country. We use Sentinel‐1 Interferometric Synthetic Aperture Radar time series to map and analyze, for the first time, surface velocities within ...

Quantifying the Effects of Volcanic Snow Cover on InSAR Coherence Using a Computationally Inexpensive Neural Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Interferometric Synthetic Aperture Radar (InSAR) measurements constrain ground movement across volcanic systems where the signal coherence remains high enough to retrieve quality phase information. A common phenomenon that degrades this coherence at volcanoes is snow cover.
