Best Practice for Integrating InSAR and GNSS Observations in High-Density GNSS Networks

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Interferometric synthetic aperture radars (InSAR) is widely used to monitor ground deformation, but its results are relative to a local satellite-based reference system.

Time series InSAR surface deformation monitoring in extremely difficult area based on track refining control points selection

Zhongguo dizhi zaihai yu fangzhi xuebao, 2021
The extremely difficult area has the characteristics of extremely rugged terrain, complex geographical environment and sparse permanent scatterers. Therefore, an improved SBAS-InSAR technology is designed to monitor the surface deformation. In this paper,

Characterisation and multiphase flow modelling of a rock avalanche turned into a supraglacial debris flow: Insights from Mt Job, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Photographs before (left) and after (right) the May 2023 landslide in Mt Job, Mount Meager Volcanic Complex, British Columbia, Canada. The initial rock avalanche impacted the glacier, producing a 4.5‐km‐long debris flow that ran over it and down the valley.

Investigating continental deformation using PS InSAR

, 2015
I use Persistant Scatterer Interferometric Synthetic Aperture Radar (PS InSAR) to measure interseismic strain accumulation across the Kunlun Fault, observe and model the postseismic signal associated with the Mw 7.8 2001 Kokoxili earthquake, and map strain in Western Turkey.

DeepOT: A Deep Learning Framework for Pixel‐Level Ground Surface Displacement Estimation From SAR Amplitude Imagery

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Monitoring ground surface displacement is critical for understanding geophysical processes and mitigating natural hazards, yet conventional Synthetic Aperture Radar (SAR) techniques are often limited by decorrelation, complex terrain, and heterogeneous motion.

Volcanism at Piton de la Fournaise as an Analog for Chloris Mons, Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Identifying and investigating terrestrial analogs for Venus volcanic activity is necessary to prepare for the planned upcoming missions to Venus. We propose volcanism at Piton de la Fournaise, a frequently active oceanic shield volcano, as an analog to volcanism at Chloris Mons, Venus.

Towards the development of a landslide activity map in Slovenia

Frontiers in Earth Science
To create the landslide activity map, we implemented and tested the procedure to fully utilise the 6-day repeatability of the Sentinel-1 constellation in three pilot areas in Slovenia for the observation period from 2017 to 2021.
