Abstract

We significantly improved a numerical seismo-thermo-mechanical model to - besides long-term subduction dynamics - also accurately simulate the dynamics of short-term seismogenesis. Through adaptive time stepping and rate-and-state friction we can resolve events from aseismic to coseismic slip, including wave propagation. Through High-Performance-Computing and non-linear solvers we can accurately do this in 3D. Results showing grid size convergence demonstrate the existence of a fault parallel length scale on the order of (tens of) meters for slow slip transients.
