Abstract

This study compiles a parametric earthquake catalog covering Northern Algeria and its adjacent areas from 1658 to 2018. The choice of moment magnitude MW as a unified scale of the compiled catalog ensures the non-saturation of the magnitude for large magnitude events and direct link or access to the physical parameters of the ruptured faults. The compilation process was performed based on data merging from various national and international heterogeneous magnitude sources together with intensity sources from the historical period. Several empirical relationships have been used to link different magnitude scales and intensity, namely Imax, mb, mbLg, MD, ML and MS. In addition, a new set of empirical relationships was established using the General Regression Method (GOR) to link the local magnitude ML and the duration magnitude MD scales used by the Algerian (CRAAG) and Tunisian (NIMT) national seismological agencies, respectively. The obtained earthquake catalog (PECAAR) includes 11,084 events that occurred during the period from 1658 and the end of 2018, with magnitudes MW ≥ 2.8, registered within the area delimited by longitudes 3° W and 10° E and latitudes 32° N and 38° N. The analysis of time variation of the magnitude of completeness mc estimated using the Maximum Curvature method reveals that mc drops to about 4 and 3 starting from 1840 and 1997, respectively. In space, the recent distribution of the magnitude of completeness estimated using the last decade’s data shows quite stable values ranging between 2.8 and 3.4.
