An Overview of Seismology at the Geological Survey of Western Australia

Seismological projects have been part of the operational research at GSWA for the past 10 years. Up to now, they have been quite low-key, concentrating on imaging specific geological targets such as the Capricorn Orogen, which investigated the collision between the Pilbara and the Yilgarn Cratons; the Albany-Fraser Orogen and the SE margin of the Yilgarn Craton; The Canning Basin; and the area between the Western Australian Craton and the North Australian Craton. These studies have been in conjunction with geological mapping, active seismic and MT.

Now we are conducting longer-term projects in conjunction with GA, such as baseline monitoring in the Canning Basin, seismicity of the Goldfields Region and more detailed monitoring of the SW Seismic Zone.

However, the current big project, which we are in the first year of, is the complete 40 km coverage of Western Australia with passive seismic stations, known as WA Array. This continues the work started in other parts of the country under the EFTF as AusArray. This is a 10-year project with a specific list of products, a tight timeframe and big ambitions.
