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.
