Millimetres that Matter: InSAR and GNSS Services supporting Geohazard monitoring across AU and NZ

From creeping faults to sinking cities, geohazards leave measurable fingerprints on the Earth's surface. Australia and New Zealand are increasingly leveraging the complementary strengths of GNSS and InSAR to monitor, understand, and respond to a wide range of geohazards. From millimetre-scale deformation measurements to regional monitoring services, this presentation will share lessons learned, innovative applications, and future opportunities for integrating geodetic observations into hazard management. Featuring examples from national programmes, collaborative research, and operational services, the presentation will explore the growing role of modern geodesy in hazard detection, situational awareness, and community resilience.
