Seismic Activation Model Reconciliation (submitted to KeAI Earthquake Science)

Abstract

A strain energy diffusion model is presented as a means of reconciling different seismic moment time scaling relations presented by previous seismic activation models. Using similarity solutions to the 1D modified porous medium equation, anomalous diffusion of strain energy along the mainshock fault is demonstrated to increase strain energy density at the mainshock hypocenter while decreasing strain energy density elsewhere until mainshock rupture occurs.
