This project aims to determine the fundamental physical processes that link topography, seismic shaking and volcanism to the evolution of seismogenic fault networks in obliquely convergent (transpressional) plate boundary settings. We will combine detailed field and remote sensing-based structural analyses in transpressional mountain belts with advanced laboratory analogue and numerical experiments to evaluate: 1) how bursts of strong seismic shaking perturb fault zone evolution through time; 2) the contribution of topography and gravitation loading to fault interactions and earthquake generation; and 3) feedbacks between fault network development, the spatial distribution of volcanic centres, seismic shaking and ore deposits.

该项目旨在确定将地形，地震震动和火山症与地震发生断层网络在倾斜（换压）板块边界设置中联系起来的基本物理过程。 我们将与高级实验室类似物和数值实验相结合的详细场和基于遥感的结构分析，以评估：1）如何随着时间的推移爆发强烈的地震摇动扰动断层区域的演化； 2）地形和重力加载对断层相互作用和地震产生的贡献； 3）在断层网络发展，火山中心的空间分布，地震震动和矿石沉积之间的反馈。
