Victorian quake shows value of Australian earthquake monitoring

One month after the largest earthquake to hit south-eastern Australia in more than 200 years, small aftershocks are still being recorded by Geoscience Australia’s National Earthquake Alerts Centre (NEAC).

The 5.9 magnitude earthquake north of Rawson in Victoria on 22 September was felt across six states and territories, including in the major centres of Melbourne, Hobart, Adelaide, Canberra, and even Brisbane.

Minister for Resources and Water Keith Pitt said the quake has demonstrated the valuable role the Australian Government’s world-renowned NEAC plays in detecting and preparing for disasters.

“Seismic analysts were able to provide Emergency Management Australia’s National Situation Room with preliminary details about the size, location and depth of the quake approximately 10 minutes after this earthquake occurred,” Minister Pitt said.

“This information helped local emergency managers gauge the severity of the quake and start mobilising their response.”

The NEAC has detected approximately 30 aftershocks in the month following the quake, ranging in magnitude from 2.2 to 4.1, including one just last night.
