Australian geomagnetic observatory network monitors space weather hazard – 180 years on
Geoscience Australia’s geomagnetic observatory network covers one-eighth of the Earth. The first Australian geomagnetic observatory was established in 1840 in Hobart. This almost continuous 180-year period of magnetic-field monitoring provides an invaluable dataset for scientific research.
Geomagnetic storms induce electric currents in the Earth, and feed into power lines through substation neutral earthing, causing instabilities and sometimes blackouts in electricity transmission systems. Power outages to business, financial and industrial centres cause major disruption and potentially billions of dollars of economic losses. The intensity of geomagnetically induced currents is closely associated with geological structure.
Geomagnetic storm events across three decades have been analysed to develop a statistical model of geomagnetic storm activity in Australia and the model used to predict the intensity of geomagnetically induced currents in Australia's modern-day power grids. Modelling shows the induced electric fields in South Australia, Victoria and New South Wales caused by an intense magnetic storm that occurred in 1989. Real-time forecasting of geomagnetic hazards using Geoscience Australia’s geomagnetic observatory network and magnetotelluric data from the Australian Lithospheric Architecture Mapping Project helps develop national strategies and risk assessment procedures to mitigate space weather hazard.
