A brief history of earthquake monitoring in Australia
The Research School of Earth Science at the Australian National University (ANU) in Canberra operated seismograph networks in southeast New South Wales and eastern Victoria from 1958. These were used to determine the location and magnitude of many thousands of earthquakes, with data published in a monthly Local Earthquake Bulletin. From July 1988, only events larger than magnitude ML 2.0 were located. These Bulletins were discontinued in June 1993.
Geoscience Australia (GA, formerly the Australian Geological Survey Organisation – AGSO, previously Bureau of Mineral Resources – BMR) in Canberra has been operating seismographs since 1962. The Mundaring Geophysical Observatory near Perth has been monitoring earthquakes in Western Australia since 1959.
The University of Tasmania operated a seismograph network in Tasmania from 1960, including a number of telemetered sites for the Hydro-Electric Commission. The operation of a majority of this network was taken over by the SRC, and the network continues to operate today in expanded form.
The University of Adelaide, through Dr David Sutton, installed a network of seismographs in South Australia from 1962. This network later moved to Flinders University, and then to the South Australian Government as the Sutton Earthquake Centre, originally in the South Australian Department of Mines and Energy (SADME), later in Mines and Energy South Australia (MESA), then in Primary Industries and Resources South Australia (PIRSA), then under DMITRE Minerals (Department for Manufacturing, Innovation, Trade, Resources and Energy), and finally under the Department of State Development before the observatory was closed in mid 2017.
The Seismology Research Centre started at Preston Institute of Technology. The institute was renamed Phillip Institute of Technology, and later merged with RMIT University. RMIT sold the SRC group to a private company, Mindata Australia, which was in turn acquired by ESS Earth Sciences (formerly ES&S). The SRC has been operating seismographs in southeast Australia since 1976. The current network includes over 100 permanent sites throughout Tasmania, Victoria, New South Wales, and Queensland. The SRC aims to locate earthquakes with a precision sufficient to delineate active faults, and has located thousands of events.
The University of Queensland first operated a local seismograph network northwest of Brisbane in 1977. This later moved to the Queensland Government Department of Mines and Energy, but returned to the University in 1994 when the Queensland University Advanced Centre for Earthquake Studies (QUAKES) was formed.
