Megathrust earthquakes: Inferences from numerical modelling and explainable artificial intelligence

Our understanding on the main controls of megathrust seismicity is far from complete, particularly on how modelling the system in 3D affects the related dynamics. In this thesis, I investigated the role of 3D slab loading along convergent margins on the generation of large megathrust seismicity using numerical modelling. In addition, I demonstrated the use of explainable artificial intelligence (XAI) in solving some facets of this problem.
