Special Issue Information

Dear Colleagues,

In our first two Special Issues, opened from 2021 to 2023, we published 28 state-of-the-art research articles covering diverse topics in InSAR and geological disasters (https://www.mdpi.com/journal/remotesensing/special_issues/InSAR_Geological_Disasters; https://www.mdpi.com/journal/remotesensing/special_issues/ES569JPZ29). These excellent reports significantly contribute to further developments in the monitoring and modeling of geological disasters using InSAR techniques. Meanwhile, an increasing number of scholars are expressing their willingness to submit and publish their research output on this topic. Therefore, we are launching a third edition of this Special Issue.

Interferometric synthetic aperture radar (InSAR) has demonstrated its potential in monitoring geological disasters related to subsidence, landslides, earthquakes, and volcanoes. Such monitoring results provide significant information for further physical modeling, driving mechanism interpretation, developments in early warning technology, and the management and formulation of policies by authorities and stakeholders. Recently, more advanced InSAR methods have been developed for geological disaster monitoring and modeling. For instance, the integration of multi-sensor SAR data improves the temporal resolution. Advanced distributed scatterer interferometry algorithms increase the possibility of measuring low-coherent areas. Introducing machine/deep learning improves the quality of phase unwrapping and decreases errors in InSAR processing. Deep neural networks even make it possible to directly invert the geophysical parameters of disasters from SAR interferograms. Uncertainty analysis of InSAR results further increases the readability of monitoring results.

This Special Issue will publish studies covering different applications by InSAR technique, especially the monitoring and modeling of geological disasters. Topics may cover any aspect from ground displacement monitoring to inversion of geophysical parameters. Multi-source data integration (e.g., InSAR, GNSS, and ground sensors), advanced InSAR approaches, geological disaster modeling, and other relevant issues are all welcome. Monitoring results based on InSAR techniques promote the development of remote sensing science and expand the scope of remote sensing technique applications.

Articles may address, but are not limited to, the following topics:

  • Multisource monitoring data integration;
  • Geohazard detection;
  • Disaster catalog compilation;
  • Parameter inversion;
  • Innovative InSAR applications;
  • Advanced InSAR algorithms.

The Qilian Mountains, located on the northeastern edge of the Qinghai–Tibet Plateau, are characterized by unique high-altitude and cold-climate terrain, where permafrost and seasonally frozen ground are extensively distributed.

The Qilian Mountains, located on the northeastern edge of the Qinghai–Tibet Plateau, are characterized by unique high-altitude and cold-climate terrain, where permafrost and seasonally frozen ground are extensively distributed. In recent years, with global warming and increasing precipitation on the Qinghai–Tibet Plateau, permafrost degradation has become severe, further exacerbating the fragility of the ecological environment. Therefore, timely research on surface deformation and the freeze–thaw patterns of alpine permafrost in the Qilian Mountains is imperative. This study employs Sentinel-1A SAR data and the SBAS-InSAR technique to monitor surface deformation in the alpine permafrost regions of the Qilian Mountains from 2017 to 2023. A method for spatiotemporal interpolation of ascending and descending orbit results is proposed to calculate two-dimensional surface deformation fields further. Moreover, by constructing a dynamic periodic deformation model, the study more accurately summarizes the regular changes in permafrost freeze–thaw and the trends in seasonal deformation amplitudes. The results indicate that the surface deformation time series in both vertical and east–west directions obtained using this method show significant improvements in accuracy over the initial data, allowing for a more precise reflection of the dynamic processes of surface deformation in the study area. Subsidence is predominant in permafrost areas, while uplift mainly occurs in seasonally frozen ground areas near lakes and streams. The average vertical deformation rate is 1.56 mm/a, with seasonal amplitudes reaching 35 mm. Topographical (elevation; slope gradient; aspect) and climatic factors (temperature; soil moisture; precipitation) play key roles in deformation patterns. The deformation of permafrost follows five distinct phases: summer thawing; warm-season stability; frost heave; winter cooling; and spring thawing. This study enhances our understanding of permafrost deformation characteristics in high-latitude and high-altitude regions, providing a reference for preventing geological disasters in the Qinghai–Tibet Plateau area and offering theoretical guidance for regional ecological environmental protection and infrastructure safety.
