The Devastating 2022 M6.2 Afghanistan Earthquake: Challenges, Processes, and Implications
Geophysical Research Letters, Volume 50, Issue 11, 16 June 2023., 2023 Abstract On June 21st, a Mw6.2 earthquake struck the Afghan‐Pakistan‐border‐region, situated within the India‐Asia collision. Thousand thirty‐nine deaths were reported, making the earthquake the deadliest of 2022. We investigate the event's rupture processes by combining seismological and geodetic observations, aiming to understand what made it that ...

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 5, May 2023., 2023 Abstract Understanding the crustal structure and the storage and movement of fluids beneath a volcano is necessary for characterizing volcanic hazard, geothermal prospects and potential mineral resources. This study uses local earthquake traveltime tomography to image the seismic velocity structure beneath Nabro, an off‐rift volcano located within the ...

Journal of Geophysical Research: Earth Surface, Volume 128, Issue 4, April 2023., 2023 Abstract The Greenland ice sheet has become a significant contributor to global sea level rise over the last 40–50 years. Approximately half of Greenland's mass loss since 1992 was due to increased ice discharge from marine‐terminating outlet glaciers.

A phase-decomposition-based polarimetric coherence optimization method
International Journal of Applied Earth Observations and Geoinformation, 2022 The interference between different scattering components in distributed scatterer (DS) makes it difficult to estimate the phase from DS. Recently, some methods based on eigenvalue decomposition (EVD) are proposed to separate scatterer components from DS,

Forest Height Estimation Based on P-Band Pol-InSAR Modeling and Multi-Baseline Inversion
Remote Sensing, 2020 The Gaussian vertical backscatter (GVB) model has a pivotal role in describing the forest vertical structure more accurately, which is reflected by P-band polarimetric interferometric synthetic aperture radar (Pol-InSAR) with strong penetrability.
