Abstract

The ANSIR Major National Research Facility significantly enhanced national capacity for recording distant seismic events using recorders distributed across the continent. Both the broad-band and short-period recorders have been deployed in innovative experimental designs that have made major contributions to the understanding of 3-D structure beneath the Australian Region. The Facility continues its national role with investment in equipment suitable for both seismic and electromagnetic sounding.

Passive seismic recording offers a cost-effective way of obtaining structural information across substantial areas of the continent. The results are valuable in their own right, but can also provide important constraints on seismological structure that are valuable in planning more expensive deep crustal reflection profiles.
