To forecast these hazards within a socially relevant timeframe, two key elements are required: precise observations and a broad range and scope of applications. The former is essential for providing comprehensive space-time data necessary for accurate imaging and modeling of crustal dynamics, while the latter enables a deeper understanding of both historical and ongoing hazards. As a space geodetic tool, Interferometric Synthetic Aperture Radar (InSAR) is widely used to map surface deformation across large areas with high spatial density. We can apply InSAR to monitor changes in the ground surface around faults in response to tectonic forces and to assess volcanic hazards by measuring ground deformation associated with the migration of magma toward the surface before volcanic eruptions. In this webinar, I present two studies showcasing the applications of InSAR to better understand seismic and volcanic hazards. The first study provides a comprehensive picture of seismic risk along the 1600 km-long intra-continental Altyn Tagh Fault over the Tibetan Plateau, revealing spatial variations in strain accumulation that advance seismic hazard assessment across the region. The second study introduces a high-resolution InSAR-derived database of global volcanoes, demonstrating the potential to automatically identify volcanic unrest through the integration of deep learning approaches.
