The North Africa Seismological Group (NASG) is a collaboration of researchers from leading universities and research institutes in North Africa. It was founded in 1999 at the Abdus Salam International Centre for Theoretical Physics (ICTP, Trieste, Italy) with the scientific support of the Structure and Non-linear Dynamics of the Earth, Earth System Physics Section (SAND/ESP), and the financial support of the Office of External Activities NET40-OEA/ICTP.
The NASG main objective is to coordinate advanced seismological research in North Africa, and to gather scientists from North African countries to work on joint research project aiming at seismic hazard. The coordination of the research activities is promoted both at national and regional scales through frequent visits and exchanges of the partnership that evolved, during the years, from the regional scientific meetings of the working group, to international manifestations and workshops. The scientific field of cooperation is seismology, seismotectonics, engineering seismology, geodynamics with GPS monitoring, regional seismic hazard assessment, seismic zoning modelling structure and microzoning for megacities and urban areas.
The NASG involves the countries of Algeria, Egypt, Libya, Morocco and Tunisia. In this work, we present one of our most recent outputs represented in the compilation of the earthquake catalogue in North Africa. In addition to this earthquake catalogue, a more specialized catalogue was created for the purpose of neo-deterministic approach for seismic hazard mapping in North Africa based on the compilation of synthetic seismograms (Panza, 2001). The preliminary results are presented and compared with results from the probabilistic approach by GSHAP (2000).
