This project aims to investigate the present-day tectonic stress field of Australia using detailed analysis of stress magnitude data and state-of-the-art 3D geomechanical-numerical modelling across spatial scales. Tectonic stresses control the Earth’s deformation and are a primary cause of collapse of subsurface structures. This project expects to improve our knowledge of the causes of the tectonic stress field of Australia and its consequences for earthquake risk assessment, safe and sustainable usage of underground environments for groundwater exploration and production, CO2 sequestration, waste disposal, mine stability, exploration and production of hydrocarbon and geothermal resources.

该项目旨在通过对应力大小数据的详细分析和跨空间尺度的最先进的三维地质力学数值建模，调查澳大利亚现今的构造应力场。构造应力控制着地球的变形，是地下结构坍塌的主要原因。该项目预计将提高我们对澳大利亚构造应力场的原因及其对地震风险评估的影响的认识，安全和可持续地利用地下环境进行地下水勘探和生产，二氧化碳封存，废物处理，矿山稳定性，碳氢化合物和地热资源的勘探和生产。
