“…According to scaling relationships (e.g., Thingbaijam et al, 2017;Wells & Coppersmith, 1994), this range of surface lengths for reverse faults generally correspond to maximum moment magnitudes of about 6.4-6.8 (Table 5). These magnitude estimates are compatible with intensities ranging between VII and VIII for moderate to large historical earthquakes reported for this region since the eleventh century, and particularly with that of the 1755 Fès-Meknès Earthquake (Blanc, 2009;Cherkaoui et al, 2017;El Mrabet, 2005;Peláez et al, 2007;Mourabit et al, 2014;Roux, 1934). Since scaling laws are statistically consistent with self-similarity (e.g., Thingbaijam et al, 2017), relationships between rupture (2) a thick-skinned option where the reverse fault connects to inherited basement faults, dipping at 60°.…”

“…1). Along the southern border of the Rif Mountains, the region of Meknès and Fès has experienced almost 10 earthquakes since the eleventh century (Roux, 1934;El Mrabet, 2005;Paláez et al 2007;Blanc, 2009;Mourabit et al, 2014;Cherkaoui et al, 2017), with three moderate to large events with intensities ranging between VII and VIII in 1045, 1624, and 1755 (Fig. 1).…”

“…In close agreement with the distribution of the instrumental seismicity, these historical events are mainly located in the Tell-Rif Alpine chain (Figure 1). Along the southern border of the Rif Mountains, the region of Meknès and Fès has experienced almost 10 earthquakes since the eleventh century (Blanc, 2009;Cherkaoui et al, 2017;El Mrabet, 2005;Mourabit et al, 2014;Peláez et al, 2007;Roux, 1934), with three moderate to large events with intensities ranging between VII and VIII in 1045, 1624, and 1755 (Figure 1). Overshadowed by the large Lisbon Earthquake in the historical archives (e.g., Blanc, 2009), the precise date of the Fès-Meknès Earthquake is unclear, with Spanish and Portuguese sources referring to a shock on November 18, which could be interpreted as an aftershock of the Lisbon Earthquake (Pereira de Sousa, 1919;Roux, 1934;Vogt, 1984), whereas Arab sources document it on November 27, with an epicentral intensity of VIII that was restricted to the Saïss Region (Moratti et al, 2003;Poujol et al, 2017).…”

In intraplate tectonic regions characterized by moderate seismic activity, the recognition of active zones of deformation has long been a challenging task (e.g., Landgraf et al., 2017). Like Northern Africa, such regions are generally characterized by low hazard but high risk due to the concentrations highly vulnerable population and/or infrastructures (Moreno et al., 2004). Moreover, when low strain rates are combined with meteorological and anthropogenic overprints, the geomorphic signatures associated with active faults fade away as fault slip rates decrease. Consequently, diagnostic criteria established in areas of high strain rates may not be effectively applied. Furthermore, low-levels of seismic strain induce low displacement rates, which may be distributed over numerous fault segments rather than localized on a single fault. At the regional scale, such a distribution of the tectonic deformation can also obscure the seismogenic potential of any given single structure, as, for example, the La Rouvière Fault reactivation during the 2019 M w 4.9 Le Teil Earthquake (Ritz et al., 2020), in southeastern France, which was previously considered as inactive (Jomard et al., 2017).Part of the peri-Mediterranean Alpine chain surrounding the Alboran Sea, the Rif Mountain belt in Morocco is an area of moderate tectonic activity. Located within the diffuse convergence zone between the Nubia Abstract Located at the southern boundary of the Alpine chain in Morocco, the deformation front of the Southern Rif Mountains is a region of moderate tectonic activity, which makes it a good natural laboratory to understand whether, and how, low compressional strains are located on specific structures. Along the ≈80 km-long left-lateral, transpressive and reverse fault zone that runs at the toe of the Pre-Rif Ridges, an analysis of high-resolution digital topography provides new geomorphic lines of evidence supporting Quaternary activity along, 20 km-long fault segments. The fault zone can be divided into the Meknès and the Fès segments, which are constrained at depth by reactivated, NE-trending basement faults, delimitating paleo-grabens associated with the Late Triassic-Jurassic opening of the Atlantic Ocean. For selected sites, we used in situ-produced 36 Cl, 10 Be, and 26 Al and high-resolution topography to infer the timing of abandonment of fluvial markers, which suggest incision rates on the order of 0.6-2 mm/yr. Given their lengths, scaling laws suggest that the identified fault segments should root at about 7-12 kmdepth, possibly reactivating former basement normal faults and making them potential seismogenic sources capable of generating M w 6+ earthquakes, with return times of the order of several hundreds of years. Our new morphochronological data set confirms that the Southern Rif deformation front is a key structure that may have accommodated most of the lateral extrusion of the Rif between the Nubia and Iberia tectonic plates.Plain Language Summary In Morocco, the population may suffer from the dramatic consequences of ...

“…1) would have been the cause of several topographical upheavals (El Mrabet, 1991;Chaouki, 1991) [17][5] and many large-scale landslides (El Fellah et al 1996, Labriki et al 2019 [16][23].The fez earthquake on 11-05-1624 (tab. 1) was considered, with the Lisbon earthquake in 1755, as the strongest historical seismic event that affected Fez and its surroundings (Cherkaoui et al, 2017) [8]. So, due to the proximity of the Tamda landslide to the epicentral region of the Fez earthquake, and its position on the southern limit of the central Middle Atlas great fault, we can consider this dam landslide as a contemporary seismic event.…”

Large landslides are the regular natural hazards frequent in the mountainous areas. They often defined as the movement of a mass of rock sufficient to forms a landslide dam or barrier lake, which obstruct the river water flow. The "Tamda" lake, located 15 km to the north of the Jbel Bouyablane summit, is a natural dam formed by landslide blocked Tmorghot wadi and modified the water circulation and sedimentation. This landslide seem to be triggered by a superposition of several geological factors (predisposition and trigger).In fact, the predisposition inherent in the structural and tectonic setting (strike, dipand fault planes) of the Eastern Middle Atlas allow to determine the nature and the form of the mass movement. In addition, the dissolving and the undermining due to the water flow, and the seismic activity related to the central Middle Atlas great fault, are the main triggering causes of this Morphodynamic and Structural Analysis of Tamda Landslide Dam (Middle Atlas, Morocco)
