Summary: Earth observation satellites are important for monitoring hazards in large-scale and remote areas. However, the use of Synthetic Aperture Radar (SAR) data is geographically variable, with limited uptake in countries like Australia. The European Space Agency Sentinel-1 satellite mission provides a new opportunity to systematically assess hazards globally, with a focus on how SAR data can benefit national hazard monitoring and assessment.

Summary: The rise of minewater after coalfield abandonment can result in significant changes in hydrogeological conditions, necessitating monitoring to prevent groundwater contamination and surface flooding. This study presents a method using SAR measurements to remotely monitor the rise of minewater in near real-time. The approach is validated in the Horlivka mining agglomeration, Ukraine, revealing a potential environmental catastrophe with potentially radioactive minewater reaching the natural water table between May and August of 2024 due to military conflicts in Donbas.

Summary: This paper takes the gypsum mine goaf in Diaodao District, Jingmen City as an example, and investigates the overall structure and distribution characteristics of the gypsum goaf. It uses InSAR and GNSS technology to analyze the ground deformation of the goaf and evaluate its stability. The research shows that two subsidence areas and three deformation areas were identified using DInSAR and time series InSAR, respectively, and the deep buried areas in the goaf were monitored by GNSS. The surface deformation is dominated by horizontal displacement, and the direction of horizontal displacement points to the goaf.

Summary: Artificial islands and land reclamation are crucial for expanding urban space in coastal cities, but they can cause ground subsidence. Monitoring land subsidence and predicting future deformation trends are important for mitigating damage and implementing effective measures. This research collected SAR images and used various methods to detect and predict land deformation in Xiamen and Zhangzhou cities, providing valuable guidance for the design and construction of infrastructure in these areas.

Summary: Remote sensing geodetic observations play an important role in earthquake monitoring and response, with the Geodetic Centroid (gCent) catalog introduced in this study. Analysis of 74 earthquakes using InSAR and optical observations shows that the centroid models compiled into the catalog are comparable to seismically inferred magnitudes. Limitations of the gCent catalog are highlighted due to remote sensing imaging constraints and simplified earthquake source descriptions.

Summary: The April 2013 slope failure at Rio Tinto Kennecott Copper's Bingham Canyon Mine was arguably the world's largest ever in-pit slope failure, resulting in the loss of approximately 145 million tonnes of rock and waste dump material. Although there were no injuries or loss of life, it led to the loss of mining equipment and significant production interruption.

Summary: To prevent landslide and collapse in the mining area, it is important to understand the surface deformation information and closely monitor its development. This paper proposes a method that utilizes SBAS technology to extract high-resolution deformation information and uses Kriging interpolation to fill in missing values in the monitoring results. Experimental results demonstrate the reliability and effectiveness of the method, providing a scientific basis for mine surface deformation monitoring.
