Reconciling stress transfer physics with statistical learning. Modified from Mignan (2018). Right-lateral Coulomb stress field for optimally oriented faults when the mainshock releases part of the regional stresses (left panel) or all the regional stresses (central panel) and radial stress field based on an analytical formulation with power-law decay (see e.g., Dieterich, 1994 – right panel). The radial pattern matches aftershock observations, at first order. First two stress fields generated with Coulomb3 (Lin & Stein, 2004; Toda et al., 2005).
