Caught in a vice: Modelling crustal deformation in Papua New Guinea

点击翻译按钮获取中文摘要

Papua New Guinea is trapped between the collision of the Australian and Pacific Plates. This proposal uses GPS methods to measure and model the tectonic motion across Papua New Guinea, identifies and quantifies areas undergoing regional deformation near plate boundaries and within tectonic blocks, and evaluates the tectonic processes associated with such deformation. Numerical models will be developed to match the observed site motions, thereby revealing the nature of the active plate boundaries and the characteristics of the Earth's crust and mantle. The project will produce new results necessary for assessing the tectonic hazards of Papua New Guinea.
