Queensland’s 5.6 Quake Spurs Aftershocks and Rapid Seismic Monitoring

Geoscience Australia is deploying portable sensors to capture the aftershock sequence, strengthening local tracking.

Overview

  • The magnitude-5.6 earthquake struck inland from the Sunshine Coast near Kilkivan and Gympie on Saturday, with shaking reported across eastern Australia from Brisbane to Cairns and Sydney.
  • It was the largest onshore earthquake in Queensland in about half a century and the biggest in the state since an offshore 5.8 event in 2016.
  • More than 15 aftershocks have been recorded since the mainshock, mostly very small with magnitudes below 2.0.
  • Reported damage was limited, with experts noting that cyclone-rated construction in Queensland helped buildings withstand the shaking.
  • The Insurance Council of Australia says most home policies cover earthquake damage, though claims can be denied if losses are deemed pre-existing, so homeowners are urged to keep thorough property records.
