Seismic activity occurs from time to time in the Brisbane region but generally at such a low level that has little to no community impact. For this reason, earthquakes rate quite low as a disaster risk for our city.
On 30 July 2015, a 5.3 magnitude earthquake offshore of Eastern Queensland in the Coral Sea was felt in Brisbane. This earthquake produced multiple aftershocks, the largest of which measured 5.7 on the Richter scale. However, while a few residents reported feeling their homes shake, there was no reported damage in the Brisbane Local Government Area.
A maximum Richter magnitude of 6.5 is theoretically possible within the region, which includes Brisbane. Such an event would be capable of generating highly damaging effects at the source but is an extremely unlikely event for Brisbane.
Brisbane City Council's Disaster Management Plan takes a comprehensive, all-hazards approach for any type of disaster or emergency event. This means that while incidents can’t be predicted in their timing or location, Council prioritises zero harm, minimising impact on residents and working toward restoring services.
