Granado 2 1 Dipartimento di Scienze della Terra, dell’Ambiente e delle Risorse- DiSTAR, Università degli Studi di Napoli Federico II, Napoli, Italy 2 Institut de Recerca Geomodels, Departament de Ciència de la Tierra i de l’Oceà, Universitat de Barcelona, Spain The Ubierna-Ventaniella fault system of northern Spain is ~ 300 km long NW-SE-striking strike-slip fault system. It is made by two segments, i.e. the Ubierna and Ventaniella faults, and crosses the entire Cantabrian Mts. (Tavani et al. , 2011; López-Fernández et al. , 2018) (Fig. 1a), from the Bay of Biscay to the NW to the Duero Basin to the SE. This lithospheric fault system displays a right-lateral offset along its entire length (e.g. Hernaiz, 1994; Alvarez-Marrón, 1995; Tavani et al. , 2011), spanning from less than 4 km for the Ventaniella segment (Alvarez-Marrón, 1995) up to more than 10 km in the central portion of the Ubierna segment (Tavani et al. , 2011). The Ubierna-Ventaniella fault system has been long time considered as almost inactive: the
