Investigations were undertaken to examine active faulting, earthquake ground shaking and submarine landslides along Australia's North West Shelf (NWS). A 2,000 km-long system of newly recognized active faults is deforming the NWS in response to ongoing tectonic processes along Australia's northern plate boundary. The faults may produce large magnitude earthquakes and high levels of ground shaking. Seafloor mapping also identified numerous types of slope failures, including large complexes with volumes of ~100 km 3. Ground motion modelling illustrates the significant influence these faults have on earthquake hazards and demonstrates that earthquakes are a likely triggering mechanism for submarine slope failures.
