Introduction

The Flinders Range is one of the seismically most active area of the Australian continent, however it is relatively far from recent, active plate boundaries. The question arises as what could be the driving force for the recent tectonic activity. Apart from the active plate boundaries, either rifting due to delamination or mantle-plume could account for striking tectonic activity in within-plate geodynamic setting. Since neither of these processes has been recognized by seismic measurements, another driving force is needed to be considered.
