Earth tremors occur in the Tell Atlas because it is a young, folded mountain range that is still in the process of formation. These mountains are situated along a tectonic plate boundary, which makes the northern ranges particularly susceptible to seismic activity.12

The geological history of the region involves complex mountain-building processes that occurred during the Paleogene and Neogene periods, involving the uplift of folded rock layers and the movement of sediment sheets. Because the range continues to evolve geologically, it remains subject to the earth tremors that characterize such active tectonic zones.1
