Australian IMS Stations

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) requires the establishment and operation of more than 300 facilities to monitor the earth for any signs of a possible nuclear explosion. Australia hosts 22 IMS stations and a radionuclide laboratory - the third largest number of facilities in the IMS network. Some of these facilities existed before the CTBT was negotiated and many have been built since. The last was completed in 2018. As Australia’s National Authority for implementation of the CTBT, ASNO works with Australian agencies and institutes to ensure Australia meets its treaty commitments.

Australian stations stretch from 12 degrees south of the equator to 68 degrees south and from longitude 63 to 159 degrees east.

The radionuclide stations and laboratory are operated by the Australian Radiation Protection and Nuclear Safety Agency. The stations at Melbourne and Darwin have facilities both for particulate monitoring and for noble gas monitoring.

The seismic and infrasound stations at Warramunga are operated by the Australian National University. Other seismic, infrasound and hydroacoustic stations are operated by Geoscience Australia (GA). The Alice Springs (PS03) station is run by GA jointly with the United States Air Force Technical Applications Centre.
