The Warramunga Seismic and Infrasound Research Station comprises a 24-element broad-band seismic array and an 8-element infrasound array. The array are certified primary stations under the Comprehensive Nuclear Test Ban Treaty (CTBTO) and data is provided by satellite link to the International Data Centre in Vienna, Austria in real time.
The station uses arrays of seismometers spread over a distance of 20 kilometres to detect tremors from nuclear testing on the ground, and infrasound sensors to detect atmospheric waves from nuclear testing in the air. The location of the sensors was chosen in consultation with the Warumungu people, from whom the land is leased, so they wouldn’t interfere with sacred sites.
While the primary purpose of Warramunga is to service the CTBTO, the data it collects is also invaluable to researchers from the ANU Research School of Earth Sciences and universities around the world. The data not only tells us about human activities on Earth, but also what’s going on deep inside it, right to the Earth’s core.
