Analysis of seismic parameters calculated such as spatial and temporal distribution of epicenters, seismic energy released, maximum magnitude recorded or calculated, in different zones under consideration of the western rift valleys branch classifying in many under zones (south Sudan, lake Albert, lake Edouard, lake Kivu, lake Tanganyika, Upemba rift, north of Zambia, lake Rukwa and lake Malawi) leads up to the establishment of the advanced seismic zoning map of seismic areas. In this study we observed: - The major seismic activity is located faults zones; - The seismic zoning shows that the seismic activity of western rift valleys is focused into three main zones: 1
