Earth Monitoring and Reference Systems

Geoscience Australia monitors and reports on earthquakes, tsunamis and the Earth's magnetic field. We contribute to international efforts to monitor nuclear tests, and provide capacity building to allow the Rabaul Volcanological Observatory in Papua New Guinea to monitor and warn citizens of volcanic eruptions. We also monitor the shape of the Earth in the Australian region, and contribute to the development of geospatial reference systems.
