The river Nile is the longest river in the world. Many dams are located along it. The high dam is largest one and the longest monitored in terms of seismicity, water levels and crustal deformation. Seismicity recorded in the Aswan area between 1986 and 2015 was investigated in detail by applying different statistical techniques. The study of the seismic catalogue allowed us to distinguish between two different depth clusters. The time dynamics and spatial distribution of the two earthquake clusters in correlation with the loading/unloading process of the Nasser Lake were further examined. The study revealed strong correlation between the shallow earthquake cluster and the water loading/unloading process, whereas deeper earthquakes can be attributed to tectonic processes, which is in good agreement with the active faults identified from geological studies.
