Hazard Space Weather

We maintain a network of geomagnetic observatories in the Australian and Australian Antarctic region which forms part of a global observatory network.

The network monitors changes in the Earth's magnetic field due to geophysical processes beneath the Earth's surface and activity in the upper atmosphere, and the Earth-Sun space environment.

Our magnetic field and geomagnetically-induced current modelling are used for navigation, magnetic direction finding, resource exploration and to mitigate against potential hazards generated by magnetic storms. Geoscience Australia also promotes public safety through the provision of compass and magnetometer calibration services.

During magnetic storms huge electric currents flow in Earth's ionosphere. They may cause inaccuracies in compass readings, radio broadcasts to be received in areas far from where they were intended and auroras to be seen at latitudes much nearer the equator than usual.

Our research into crustal conductivity and associated geo-electric hazard contributes to assist the power distribution industry to better understand the impact of geomagnetic activity on electrical distribution networks.

To help understand what could be at threat, we provide exposure information about buildings, demographics, community infrastructure and agricultural commodities.

We also provide around the clock access to data about people, property and infrastructure potentially exposed during an event. Our information aids in providing an understanding of the situation to targeted preparedness, response and recovery efforts.

Our products, tools and data provide a better understanding of geomagnetic hazard vulnerabilities  to plan, prepare and reduce exposure to natural hazards improving preparedness now and into the future.
