Enhanced 3-D seismic structure for Southwest Australia

澳大利亚西南部的古老岩石圈在地球物理性质和复杂的地质结构方面似乎有着鲜明的对比，同时也有着大陆上最高水平的地震。该项目旨在制作该地区的新型三维模型，将两年多来收集的新地震数据与合作调查人员先前收集的地球物理数据集相结合。随后将编制三维模型汇编，以便有效地描述克拉通及其边缘的地质结构。 这些模型将加强对区域地震引起的地震地面震动的评估，并有助于更好地了解矿产资源潜力。

The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models will subsequently be developed, to form an effective characterisation of the geologic structure of the craton and its margins. These models will provide enhanced assessment of seismic ground shaking from regional earthquakes and facilitate an improved understanding of mineral resource potential.
