Article Synopsis
- The Heihe River Basin, situated in the Qinghai-Tibetan Plateau, shows significant permafrost degradation, highlighted by 255 observations from various satellite and measurement data sources.
- The study employs a novel technique called Variational Bayesian Independent Component Analysis (VB-ICA) to analyze surface deformation and active layer thickness changes, revealing a maximum thickness of 5.7 m and seasonal deformation with a peak of 60 mm.
- This research emphasizes the effectiveness of the InSAR method in monitoring freeze-thaw patterns and highlights the growing concerns of permafrost erosion in high-elevation areas of the basin.
The 2013 Lushan Ms 7.0 earthquake occurred on the Longmenshan thrust tectonic zone, a typical blind reverse-fault type earthquake that caused the death of nearly 200 people. The investigation of the fault geometry and fault slip distribution of this earthquake is important for understanding the seismogenic tectonic type and seismic activity mechanism of the Longmenshan Fault Zone.

Based on Advanced Land Observation Satellite PHASE Array Type L-band Synthetic Aperture Radar and Sentinel-1 data, this paper obtains the annual subsidence rate in two time periods (2007-2010 and 2017-2020) and verifies the correctness by comparing the ascending and descending orbit results. Subsequently, the 11 deformation interference pairs of the three-month interval are extracted to analyze the time series displacement of deformation areas.
