Several studies have shown that, in a given region, the previous seismicity has a strong influence on the location, and probably also on the date of subsequent seismicity. This works included the observation of “stress shadows” and the Coulomb stress triggering. From these studies, it was deduced that in the time receding an earthquake, stress is accumulated not only on the fault, but also in a large region surrounding this fault. In this work, we were interested in earthquakes that occurred in the western Algiers, the Mont Chenoua (Mw 6.0), Tipasa (Mw 4.7) and Ain Benian (Mw 5.7). The results obtained show a good correlation between the regions where the variation of the Coulomb failure function is positive (ΔCFF > 0) and the distribution of the events of magnitude M ≥ 4.5 occurred during 1989 to 1996. This means that there was a transfer of stress among these three faults. The Mont Chenoua earthquake has triggered the serial events which occurred in the region.
