The active Eurasia-Nubia plate boundary runs across the Alboran Sea in theWestern Mediterranean Sea, where the connection between the Atlantic and Mediterranean water masses occurs. Earthquakes above magnitude M-w > 6 may favour the occurrence of landslides within contouritic drifts in the Alboran Sea. A compilation of recent multibeam data reveals for the first time the distribution of slope failures along the Xauen-Tofino banks, in the southern Alboran Sea. Here, we provide a detailed mapping and description of the morphology of eight Holocene landslides, including volume estimations of the failed mass and the related mass transport deposits (MTDs). The most voluminous landslide mobilized similar to 0.5 km(3) of sediment at the initial stage of slope failure, and formed a similar to 2.2-5.6 km(3) MTD. A finite-difference numerical model, assimilating the landslide to a granular flow, simulates tsunami generation and propagation for a slide similar to the most voluminous one. Simulations show that the coastline of Al Hoceima may be impacted by a similar to 0.5-m-high tsunami wave, whereas the coastline of Al Jebha may be impacted by a similar to 1-m-high tsunami wave, only similar to 13 min after sediment failure. The 0.2-m-high tsunami waves may impact the southern Spanish coast of the Iberian Peninsula similar to 20 min after slide initiation. Although the elevations of the modeled tsunami waves are modest, landslides from the Xauen-Tofino banks may represent a more dangerous source of tsunami in some parts of the Moroccan coast than earthquakes.
