Abstract
The Central Queensland Seismographic Network consisting of four short-period seismographs was established between May 1990 and March 1991 by the University of Central Queensland, the Bureau of Mineral Resources and the Queensland Department of Resource Industries. These stations have been located to provide coverage over approximately 70 000 km2 of central Queensland where the earthquake hazard and risk are above average for continental Australia. The network has enabled discriminants to be devised to distinguish local earthquakes from large blasts at the coal mines and quarries in the region; travel times from blasts are being used for studies of local crustal structure. Several small local and regional earthquakes have been detected in the short period of network operation; their relationship to the regions tectonic history is being assessed. The intensity in Rockhampton of the June 1918 Bundaberg earthquake, the largest known earthquake along the eastern seaboard of Australia, is re-evaluated. The area of strong shaking was larger than originally supposed and alluvial areas of downtown Rockhampton were subject to significant amplification of ground motion.
