The 26th May 2016 Mw6.0 Petermann Ranges earthquake: another large earthquake in an unanticipated location
01 November 2017
The 26th of May 2016 Mw6.1 Petermann Ranges earthquake was the largest earthquake within the Australian continent for 18 years and the latest of a series of large earthquakes to have occurred in an 'unanticipated' location. No evidence has been found to suggest a prior event in the geologically recent past, challenging the plate margin paradigm often adopted in intraplate environments that large earthquakes recur periodically on active faults. Had the earthquake occurred beneath a populated centre the effects may well have been catastrophic. The event therefore raises the question of whether the models we use to describe intraplate earthquake recurrence are appropriate.
Dr Dan Clark started with Geoscience Australian in 2001 in the Community Safety Division and works on understanding large earthquake behaviour on Australian intraplate faults. He develops models to describe the recurrence behaviour of rare large earthquakes that are incorporated in seismic hazard assessments from national to site specific scale.
This talk is presented as part of the Distinguished Geoscience Australia Lecturer series.
