From: Role of multiscale heterogeneity in fault slip from quasi-static numerical simulations

Schematic illustration of fault hierarchy heterogeneity and different appearances of seismic behavior. a When the smallest scale is missed, the fault behavior appears as repeating slow slip events. b When the largest scale is missing (or there is a zero-stress background), burst seismicity controlled by small patches becomes dominant. c When the largest scale patch plays a strengthening role, the burst behavior is reduced
