Australia is currently being squeezed between three active mountain belts, the Himalayas, the Papua New Guinea Highlands and the Southern Alps in New Zealand. We propose to integrate a large number of geological and geophysical databases that have been collected over the past few decades to develop a three-dimensional rheological model of the Australian continent, that is a model that predicts where and how Australia is deforming today. Combined with new, targeted field work, this model will be used to predict where earthquakes are likely to take place but also to study how our old continent is affected by these active mountain belts to create the present-day landscapes in which we live.

澳大利亚目前正处于喜马拉雅山脉、巴布亚新几内亚高地和新西兰南阿尔卑斯山这三个活跃山带之间。我们建议整合过去几十年来收集的大量地质和地球物理数据库，以开发澳大利亚大陆的三维流变模型，这是一个预测澳大利亚今天在哪里以及如何变形的模型。结合新的、有针对性的实地工作，这个模型将用于预测地震可能发生的地方，也用于研究这些活跃的山带如何影响我们的旧大陆，从而创造出我们今天生活的景观。
