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

巴布亚新几内亚被困在澳大利亚板块和太平洋板块的碰撞之间。该提案使用GPS方法来测量和模拟巴布亚新几内亚境内的构造运动，识别和量化在板块边界附近和构造块体内发生区域变形的地区，并评估与这种变形相关的构造过程。将开发与观测到的现场运动相匹配的数值模型，从而揭示活动板块边界的性质以及地壳和地幔的特征。该项目将产生评估巴布亚新几内亚构造灾害所需的新结果。

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.
