Erratum to: Neogene sediment deformations and tectonic features of northeastern Tunisia: evidence for paleoseismicity

摘要: The Neogene stratigraphic series is characterized by predominant clayey facies alternated other sand layers. outcrop and subsurface studies show varied complex styles of deformations lead to relate the structures paleoseismic events. seismicity eastern onshore offshore Tunisian margin follows master fault corridors oriented globally N–S, E–W, NW–SE that correspond bordering faults grabens syncline associated faulted drag fold NE–SW. Epicenters magnitudes between 3 5 are located along these border corridors. strata record brittle structures, including numerous deep fractures with straight high-angle dipping planes. structuring NE–SW en echelon folds synclines inside outside E–W right lateral N–S left tectonic indicates strike-slip type their seismogenic nature. Wrench movements induce mud salt diapirs, volcanoes, intrusive ascensions related seismic shocks. Seismic waves caused activity one, or most likely, several would have propagated throughout Quaternary cover producing seismites. similarity deposits, structuring, seismites Tunis-Bizerte North Hammamet-Mahdia South accredits hypothesis episodes might affected sedimentation patterns Sahalian large geographic area. events in northeastern Tunisia be reactivations through time. This consistent geomorphologic context study area, morphostructural lineaments strong control on sediment distribution, as well uplifted subsiding terrains. estimated magnitude great regional tectonically areas demonstrate experienced stress last geological its evolution. kinematic reconstruction highlights neotectonic system inducing actual this margin. Therefore, there a relationship deepseated seismicity.
