This part of Algeria was historically struck by strong earthquakes, it was particularly affected during the October 9, 1790 Oran earthquake of intensity (IX-X). The main purpose of this work is to assess seismic hazard on hard rock in order to provide engineers and planners a basic tool for seismic risk mitigation. The probabilistic approach is used in order to take into account uncertainties in seismic hazard assessment. Seismic sources are defined on the basis of recent results of seismotectonics studies. Source parameters are assessed for each seismic source either on the basis of seismicity data or geological data. The attenuation of ground shaking motion with distance is estimated by using attenuation relationships developed world-wide which fit the Algerian data. Different choices of source parameters values as well as attenuation relationships are assigned an appropriate weight in the framework of a logic tree model. Results are presented as relationships between values of peak ground acceleration (PGA) and annual frequency of exceedance, and map of hazard for a return period of 500 years. A maximum peak ground acceleration of 0.40g is obtained for the Oran site.
