The tight interactions among multiple physical processes may lead to the formation of localised flow and deformation patterns in natural systems. The spontaneous occurrence of such localisation events may significantly impact the dynamic of these systems and drastically modify their long-term behaviour. These considerations are key when investigating localised fluid expulsion from subsurface reservoirs or to explain fast streaming ice routes. Accurate predictions necessitate robust forward and inverse dynamical models capable of resolving nonlinear multi-physical processes on high spatial and temporal resolutions. Such models benefits from the latest technical advances to scale on billion of cores making geo-supercomputing an accessible tool to further understand natural processes vital to protect our society and the environment.
