| Scope |
Remarkable developments in geodetic satellites and remote sensing technologies, including GNSS, InSAR, gravimetry, and altimetry, have provided powerful tools for studying a wide spectrum of tectonic processes, ranging from earthquake nucleation, tsunami propagation, volcanism, to crustal deformation across plate boundaries. In recent years, advances in seafloor geodesy based on acoustic ranging and pressure sensors have further enhanced our ability to detect motion within submarine active fault systems and subduction zones. The growing diversity of modern geodetic data has also driven continuous innovation in data processing and modeling methods. This session seeks contributions that advance our understanding of crustal deformation processes, improve geodetic modeling techniques, or demonstrate innovative applications of geodesy for studying natural hazards and environmental change. We invite studies that employ geodetic observations to address issues related to datums/reference frames, positioning, engineering, geodynamics, Earth surface processes, and environmental monitoring. Investigations focusing on recent major earthquakes and other geological events by integrating other multidisciplinary observations, such as field surveys, seismicity, strainmeters, tiltmeters, and tide gauges, are particularly welcome. We warmly encourage early career scientists at the graduate and postdoctoral levels, especially non-native English speakers, to share their work in our session. |
