The South Australian seismic network comprises 12 short-period, permanent stations distributed over a large area of the State. The network provides earthquake monitoring down to magnitude ML ~ 2 for most of the State, with an improved location capability of ML ~ 1 for the seismically active Adelaide Geosyncline zone. At any time the permanent network can be augmented by 13 sets of portable equipment, which include 6 microprocessor controlled, battery-powered digital event recorders built in-house. The earthquake data are analysed on a dedicated Data General computer system and graphics unit. The software is an integrated, interactive system of seismic analysis routines, covering all the data processing needs of the network, from station calibrations and updating of station data, through the determination of locations and magnitudes of local earthquakes and the needs of microearthquake survey data processing, to the retrieval and display of earthquake statistics from an archived data base. The computerised seismic data processing system has been used in the routine analysis of all local earthquakes and microearthquake surveys in South Australia since the beginning of 1978.
