Through different periods of the geological era, the Al Jabal Akhdar region has faced a number of tectonic events, which mainly had an effect on the geomorphic features of the earth's surface. One of the most notable wadies located on the lower escarpment is Wadi Al Kuf. Alluvial terraces are dispersed throughout this wadi in various locations and regions. These terraces are revealed with an obvious variation in altitude, with some being higher while others abruptly dropped off in levels like behavior, where an a series of terraces and surfaces formed both underneath and above the escarpment. Possibly, Wadi Al Kuf alluvial terraces have been assigned and interpreted as alluvial terraces of a neotectonic impact, and supported to the effects of one of these tectonic eras since the alluvial terraces are clarified of non-natural and abnormally arranged. Wadi Al Kuf can be classified as a member of the morphotectonic valley in the Al Jabal Al Akhdar area due to terraces altitudes fluctuation. Most previous scientific publications on alluvial terraces in Al Jabal Akhdar, for example, Wadi Zazah, Sidi Moussa, and studies carried out by students of the Department of Earth Sciences during graduation projects on Wadi Al Mahboul, Wadi Al Nagar and Wadi Azzad revealed that these wadies are still tectonically active. Unfortunately, due to Storm Daniel, which struck part of the Al Jabal Al Akhdar Mountain from Al Marj in the west to Dernah in the east, it removed a large part of the alluvial terraces from the wadies in that area. Geologically, this storm created conditions similar to the devastating debris flow.
