Model of earthquake cycles with a slip-dependent constitutive law. Part II - Simulations

Vol. 48, nr 4

423-453

Long-term seismic activity is simulated using a 3D model of interacting faults presented in Part I of this paper. It is show that the system can generate complex behavior, with earthquakes of all sizes, characteristic earthquake cycles with features changing from one cycle to another, and interrelations between local quantities in qualitative agreement with laboratory data. By comparison of a single, two distant and two close fault behavior the role of fault interactions is studied. Interactions with a secondary fault, despite its low activity, change patterns of seismicity generated by the system.

Long-term slip movements along a zone of four parallel faults are simulated using a 2-D deterministic model. Both antiplane and inplane cases are considered for two different situations of close and distant faults. Fault interactions caused by internal stresses are weaker in the case of distant faults; therefore, we can determine their role played during the system evolution. Slip movements patterns obtained for the antiplane case show that driving tectonic forces lead the system towards a periodic, regular regime, whereas the interactions due to internal stresses play a role of random fluctuactions and destabilize the system behavior. More detailed studies of energy release patterns obtained for the inplane case show, both for regular and irregular regime, calm periods of the same length in which stresses are being built up.
