The Seismology and Mathematical Geophysics research group within the Geophysics area has broad interests ranging from elucidating lithospheric structures, to studying the inner core, to developing new methods for imaging Earth's interior.
Research in the group covers a range of activities designed to exploit the favourable location of Australia relative to the world's earthquake belts. This is reflected in extensive studies using deployments of portable instrumentation to study the structure of the Australian continent and the mantle beneath. Research in different topics of theoretical seismology and data inference are a strength of the group.
We operate the Warramunga Seismic and Infrasound Research Station (WRA) near Tennant Creek, Northern Territory. The seismic and infrasound arrays are primary stations in the International Monitoring System for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). The arrays were upgraded to meet Treaty standards in 2000. Data are sent by satellite link to the International Data Centre in Vienna, and the National Data Centre at Geoscience Australia in Canberra. The broad-band station CAN at Mt Stromlo is operated in association with the French GEOSCOPE network and a broad-band borehole instrument (WRAB) is supported at the Warramunga Array for the IRIS-IDA network as a contribution to global seismology. The group hosts the seismological component of the National Research Facility for Earth Sounding (ANSIR), which operates portable instrumentation for approved projects. The group also has a programme of ultra-low power seismic recorder development. It also has access to extensive computational facilities through the in-house Terrawulf cluster and the National Computational Infrastructure (NCI).
