Earth and Space Science, Volume 12, Issue 4, April 2025.Abstract After the construction of hydropower station, reservoir impoundment can directly affect the movement status of landslides within the reservoir area. Detecting landslides and revealing the relationship between landslide deformation and driving forces is crucial for reducing the threat of landslide hazards to residents and hydropower station in ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.Abstract Volcanic and seismic unrest on the Reykjanes Peninsula in SW Iceland that started in late 2019 after ∼800 years of quiescence has drawn wide interest to this on‐land extension of the Mid‐Atlantic spreading ridge. Here, we use seismic data collected across the larger Peninsula region, covering six volcanic systems and associated high ...

A Nonlocal InSAR Filter for High-Resolution DEM Generation from TanDEM-X Interferograms [PDF]
, 2018 This paper presents a nonlocal InSAR filter with the goal of generating digital elevation models of higher resolution and accuracy from bistatic TanDEM-X strip map interferograms than with the processing chain used in production. The currently employed boxcar multilooking filter naturally decreases the resolution and has inherent limitations on what ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.Abstract From repeat‐pass interferometry, tropospheric signals often prevent the detection of ground deformation signals. In recent years, tropospheric corrections derived from global weather‐based models have been implemented in several InSAR processing chains.
