This project aims to develop new methods to better image lithospheric and upper-mantle structures by using noise from ubiquitous ocean waves, and then use these methods to illuminate fine-scale lithospheric-asthenospheric structures in Australia, from the surface to the upper mantle. Imaging the Earth’s structure using seismic tomography is one of the most fundamental tasks of geoscience. Conventional earthquake-based seismic tomography has difficulties in deciphering fine-scale lithospheric structures. The images from this project will provide a better understanding of the nature of intraplate earthquakes and volcanoes, and improve the assessment of intraplate seismic and volcanic hazards in Australia.

该项目旨在开发新方法，利用无处不在的海浪噪声来更好地成像岩石圈和上地幔结构，然后使用这些方法照亮澳大利亚从地表到上地幔的精细岩石圈-软流圈结构。使用地震层析成像对地球结构进行成像是地球科学最基本的任务之一，传统的基于地震的地震层析成像难以解读精细的岩石圈结构图像。该项目的成果将有助于更好地了解板内地震和火山的性质，并改进对澳大利亚板内地震和火山灾害的评估。
