A Shape Optimization Approach for Inferring Sources of Volcano Ground Deformation

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract One of the main goals of volcano geodesy is to improve the understanding of how an increase in pressure related to magma accumulation causes ground deformation in order to evaluate volcanic unrest. The inversion methods used for this purpose rely on a parametrization of the shape of the crustal volume in which pressure changes due to magma ...

Observations of Coherence Changes in C‐Band SAR Linked to Snow Thermodynamics and Wind Redistribution on First‐Year Sea Ice

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present novel observations of C‐band Synthetic Aperture Radar (SAR) coherence sensitivities and patterns for snow on first‐year sea ice (FYI) consistent with snow thermodynamics and wind redistribution. Wintertime SAR coherence and backscatter change observations of landfast FYI in Dease Strait, Nunavut, Canada are made using 12‐day repeat ...

Intelligent Environmental Hazards Detection in Transmission Line Construction Area Based on Remote Sensing and GIS

Engineering Reports, Volume 8, Issue 4, April 2026.
The test results displayed reveal that the proposed method efficiently accomplishes the remote sensing image processing of the area, yielding a differential interferogram of the image. This interferogram accurately represents the area and provides a solid foundation for calculating the environmental hazard zone within the construction area.
