| Abstract: | This paper presents new seismic hazard maps of the Maghreb countries by using newly re-evaluated earthquake data catalogue in the region under consideration. For this region, there is a clear need to use common procedure and data bases through the whole Maghreb region so that seismic hazard assessments are consistent from country to country. An effort is made to assess the seismic hazard and to construct earthquake hazard maps in terms of expected horizontal and vertical PGA for a 10 per cent chance of being exceeded, expected intensity (MSK), all in an economic life time of 50 and 100 years. Also, a return period seismic hazard map for PGA≥140cm/s2 is presented. For engineering applications, earthquake hazard maps for structures with different periods are also constructed. |
