The ability to realistically model the propagation of seismic waves through the global 3D earth, taking account of all internal and surface complexity, is extremely important for predicting the response to earthquakes and imaging the interior structure. This will lead to fundamental new knowledge on Earth constitution and heterogeneity, and will have spin-off benefits in others areas such as exploring for oil and minerals, and better understanding of seismic hazard. The numerical modelling and seismic data analysis will be done on a supercomputer, thus providing important training for research students.

考虑到所有内部和表面的复杂性，对地震波在全球3D地球中的传播进行逼真建模的能力，对于预测地震响应和对内部结构进行成像至关重要。这将导致对地球构成和异质性的基本新知识，并将在其他领域产生附带利益，如勘探石油和矿产，以及更好地了解地震灾害。数值模拟和地震数据分析将在一台超级计算机上进行，从而为研究生提供重要的培训。
