Earthquakes by region

Newcastle region

Earthquake risk maps did not note the Newcastle region as being of particularly high seismicity until the damaging earthquake there in December 1989. In retrospect, the historical record shows quite a number of felt events in the region in the previous 100 years.

Although the Newcastle earthquake of December 1989 (magnitude 5.7) was not Australia's largest, this earthquake is it's most significant, in that it caused 13 deaths. Nine of these were at the Newcastle Workers club.

The earthquake caused $1.5 billion in damage. Another earthquake at nearby Ellalong, 5 years later (magnitude 5.4) caused another $40 million in damage, but did not cause any injuries or fatalities.

For more information on the Newcastle earthquake, you can visit the Newcastle Regional Museum.

The Dalton Gunning Region

The Dalton Gunning region has long been noted as an important source of seismic activity. Damaging earthquakes were located there in November 1934 (magnitude 5.6) and March 1949 (magnitude 5.5), and smaller earthquakes are still occurring in the region.

Earthquakes near Sydney

Many of the earthquakes felt in Sydney have originated to the south of the city. Significant earthquakes have occurred near Picton (1973), and near Bowral (1961 and 1994)

The Snowy Mountains Region

The Snowy Mountains region was one of the first to be intensely monitored and studied for earthquakes, partially because of the commencement of major engineering works for the Snowy Mountains Hydo-electric scheme in the 1950's. The Australian National University maintained up to 20 seismic stations in the area through the 1950's and 1960's.

Monitoring of Earthquakes

Historical Background

The first professionally operated seismograph in Australia was set up the Jesuit Religious Order at Riverview College, Sydney, in 1909, and this station still operates today.

Only a few other seismographs were set up in Australia (in the major capital cities) from that time until the late 1950's, when rapid world-wide expansion in the number of seismographs occurred (partially in response to the newly developed atomic bomb).

Today, Australian earthquakes are principally monitored by the Australian National Seismograph Network (see below), operated by Geoscience Australia (based in Canberra, ACT). There are approximately 100 stations in this network, and numerous others operated by other authorities.

Current Seismic Networks in NSW

The most important seismograph network operating in NSW is that run by the Australian Government (Geoscience Australia) as part of its Australian National Seismograph Network (ANSN). The stations it operates in NSW are listed below

 CNB Canberra  near Queanbeyan 
 MGCD Mangrove Ck Dam  ~ 35 km NW of Gosford 
     

Another important network is that operated by Sydney Water, to monitor activity in the regions around important dams.

In addition, a number of seismographs are run by independant operators, interested in seismology, including three stations in NSW Government schools (Gundaroo, Katoomba, and Penrose). These seismographs are part of a small national network run by the Australian Centre for Geomechanics (ACG). For more infomation on these and other networks, contact vic_dent at yahoo.com

Earthquake Risk

Australian Earthquake Hazard

The map to the right shows the current risk map of Australia. This shows that the regions of greatest hazard in Australia are along the west and north-west coastal area of Western Australia, and in the Flinders Ranges region of South Australia. Smaller zones of activity occur in the highlands of Victoria, the Dalton-Gunning region of NSW, and off Rockhampton in Queensland.
