Abstract
The Tunisian domain is formed following the convergence between Nubia and Eurasia which is responsible for folding and still active faulting. We used 62 earthquake focal mechanisms to constrain the present stress field of the Tunisian domain. The results show that the tectonic regime is compressional with a dominant direction NW-SE maximum horizontal principal stress direction. The focal depth distribution indicates that Northern Tunisia is an area of convergence with a thin crust and a shallow Moho. However, in the central and southern Atlas, the presence of focal mechanisms with strike-slip faulting shows that this zone is a deep seismogenic area with a thick crust.These results are consistent with the neotectonic and seismotectonic stress field determined by other studies. The neotectonic deformations of Tunisia are like the past deformations guided by the convergence between the African and the Eurasian plates.
