Delayed dynamic triggering of earthquakes: Evidences from a statistical model of seismicity

Understand

I study a recently proposed statistical model of earthquake dynamics that incorporates aging as a fundamental ingredient.

• The model is known to generate earthquake sequences that quantitatively reproduce the spatial and temporal clustering of events observed in actual seismic patterns.
• The aim of the present work is to investigate if this model can give support to the empirical evidence that earthquakes can be triggered by transient small perturbations, particularly by the passing of seismic waves originated in events occurring in far geographical locations.
• The effect of seismic waves is incorporated into the model by assuming that they produce instantaneous small modifications in the dynamical state of the system at the time they are applied.
