The seismicity analysis carried out here is based on reliable compilation of earthquake catalog obtained from different agencies. The homogeneity of the catalog is ensured by the conversion of intensities in the historical part of the catalog and different magnitude scales in the instrumental part to surface magnitude Ms, using appropriate relationships. Dependent events are removed using the windowing technique suggested by Gardner and Knopoff (1974). The magnitude of completeness mc is estimated using the maximum curvature method (Wiemer and Wyss, 2000). The residual catalog obtained after declustering including 672 events with Ms ≥ 2.8 is used for the estimation of various parameters characterizing the temporal and spatial seismic activity for the entire northern part of Algeria (b value, Z value, etc...). The results presented as seismicity rate changes and b value variation maps show recent increase in seismic activity around Algiers and Oran cities.
