Synchronization of megathrust earthquakes to periodic slow slip events in a single-degree-of-freedom spring-slider model.

ABSTRACT: Recently recognized slow slip events (SSEs) recurring in the deeper extensions of seismogenic zones along plate boundaries are drawing attention to their potential for triggering megathrust earthquakes that rupture the entire seismogenic zone. We describe how earthquakes simulated in a single-degree-of-freedom model are synchronized to the rhythm of imposed periodic SSEs. The time lag t_Q from the one most recent SSE to a seismic event varies with system parameters and may take a broad range of eligible values between 0 and T_SSE (SSE recurrence period). Earthquakes were found to synchronize with SSEs in various patterns depending on the proportion of SSE-driven loading within an SSE cycle, the recurrence period of the SSEs, and the duration of the SSEs, although synchr
