Relationship between subduction zone geometry, trench kinematics and great subduction earthquakes

2004年苏门答腊岛附近毁灭性的节礼日地震和有记录以来其他四次最大的地震都发生在俯冲带上。这项研究将比较这些俯冲带与澳大利亚大陆周围的地球动力学环境，并评估澳大利亚俯冲带是否有能力产生可能对澳大利亚东部和西北海岸构成风险的大地震和海啸。此外，东澳大利亚是一个富含矿藏的化石弧的复合体，塔斯曼海地区由碳氢化合物赋存的盆地组成，所有这些盆地都是通过俯冲过程形成的。因此，拟议的研究将改善矿产和油气勘探的基础。

The devastating Boxing Day 2004 earthquake near Sumatra and the four other largest earthquakes in recorded history all occurred along subduction zones. This research will compare the geodynamic setting of these subduction zones with those surrounding the Australian continent and assess whether the Australian subduction zones are capable of producing great earthquakes and tsunamis that might pose a risk for the east and northwest coast of Australia. Also, Eastern Australia is a composite of fossil arcs rich in ore deposits and the Tasman Sea region is composed of basins that host hydrocarbons, all of which formed by subduction processes. The proposed research will thus improve the basis for mineral and hydrocarbon exploration.
