Two maps of estimated maximum intensity distribution have been prepared for the Red Sea region by applying appropriate intensity attenuation and conversion equations, without considering the probability of exceedance. The maps are represented in two parametric elements, which are: the maximal earthquake effects and the period of observation. The significance of these maps is due to their contributory aspect of providing supplemental earthquake information pertaining to simple, but necessary seismic hazard representation of the Red Sea area. Basically, the maps are illustrative of the areas that are likely and susceptible to experience the possibility of hazardous earthquake effects as shown and indicated. The importance of this study is to give some high light on the maximal earthquake effects in the Red Sea which is one of the most important plate boundaries with frequent occurrence of moderate earthquakes. It is one of the most important passages of world trade with some important commercial ports on each flank.
