AB From swath bathymetry data and high-resolution acoustic profiles (TOPAS) several slides have beenimaged in the Alboran Ridge in the western Mediterranean. This submarine relief is the most prominentmorphological feature (> 130 km in length) in the Alboran Sea and its elongated SW-NE shape results isenhanced from the recent convergence between the African and Eurasian plates. The identified gravitationaldeposits show transparent and chaotic facies, and appear in depths ranging between 640 and 1810 m.Occurrence of slides deposits along fault escarpments affecting the seafloor reveals that submarine instabilityprocesses are mainly controlled by tectonics. Mass-transport deposits are generally composed by severaloverhead lobes of sediments. These observations suggest collectively that instability processes are frequentand may be related with faulting pulses. Instability processes represent therefore a geological risk in theregion that should be surveyed and analyzed in the future
