Abstract

The continental Quaternary and coastal deposits of Great Kabylia show typical deformation of paleoseismicity including paleoliquifaction (sismoslumps, thixotropic wedges, dish), boulders and coastal uplift. The aim of the present study is to characterize the deformations as indications of paleoseismicity and to reveal the existence of the traces of the historical earthquakes that would have affected the region of Neogene Tizi Ouzou bassin. Field observations indicate that these deformations exist in several areas of Great Kabylia. In fact, the traces of paleoseismicity have been found in the Quaternary deposits of the Neogene Tizi Ouzou basin in the southern part and also on the coast in its northern part. Among the arguments that demonstrate the seismic origins are: the thixotropic nature of deformations as well as presence of the notches at different levels of the coast. They are good indications of coastal uplift.
