This project aims at quantifying and understanding the structural dynamics within the crust leading to, during and after a great megathrust earthquake. This includes the evolution of stress in the lithosphere and identifying signatures of possible fluid migration at depth. We will exploit the dataset acquired during the 2014 M W 8.1 Iquique earthquake sequence, which is distinguished from most other great subduction earthquakes in the first place by its rich foreshock sequence but also the continuity of monitoring by the IPOC network (http://www.ipoc-network.org/welcome-to-ipoc).
