Volume 12 Article informations Contribution of neotectonic and seismotectonic data in the study of induced seismicity in Sidi Salem dam Sinda Gaieb a,*, Najet Shimi a Abstract The seismic activity, which is related to the movements of tectonic plates, is called natural seismicity. However, the induced seismicity is a seismicity generated by human activity in a supposedly geologically stable environment. North Tunisia is one of important seismic region in the country. It is one of the most earthquake prone areas. This work aims to provide a new overview of seismotectonic studies in Tunisia and the contribution of this study in obtaining a detailed knowledge of the site of Sidi Salem dam and the process of triggering seismicity around this reservoir from 1982 to 2010. The maps in this study were georeferenced and digitized by ARCGIS 10.1 software. However, we analyzed the data of water level of the dam and the seismic activity by MATLAB. The results show that the current tectonic regime varies between a deformation in compression with a NW-SE direction and a deformation in sinister strike-slip fault. Compressive deformation characterizes northern Tunisia and it has been the source of shallow earthquakes. The seismicity of the Sidi Salem reservoir is an example of the initial seismicity, the earthquake that occurred in 1987 is linked to the first filling of the dam. An increase in seismic activity around the lake was observed from the year 1982 (date of the impoundment of the reservoir) until 2010 which is the chosen period in this work. These seismic events occurred following the seasonal increase in the water level of the dam, which has reached its maximum level several times. Key words: Induced seismicity, Tectonic deformation, Sidi Salem dam, Tunisia.
