This project aims to advance understanding of the Australia-Pacific plate boundary - the Macquarie Ridge Complex - in the Southern Ocean. It will be the first study to elucidate the processes generating the world's largest submarine earthquakes not associated with active subduction, which may lead to understanding of how subduction initiates, the mechanism of earthquakes occurring at convergent margins, and more accurate estimates of earthquake and tsunami potential. This study will put Australia at the forefront of Earth Science research into the evolution of tectonic plates and has the potential to better inform hazard assessment efforts in the region, benefiting policy-makers and at–risk communities along the Australia coastline.

该项目旨在增进对南大洋澳大利亚-太平洋板块边界-麦夸里洋脊复合体-的了解。 这将是第一项阐明与活动俯冲无关的世界上最大海底地震产生过程的研究，这可能有助于了解俯冲是如何开始的，地震发生在会聚边缘的机制，以及更准确地估计地震和海啸的潜力。 这项研究将使澳大利亚处于地球科学研究板块演化的最前沿，并有可能更好地为该地区的灾害评估工作提供信息，使政策制定者和沿着澳大利亚海岸线的风险社区受益。
