This study aims to investigate the failure mechanisms and factors influencing cliff stability of soft rock cliffs, specially focusing on a clastic coastal area of the mid-western Adriatic Sea of the Abruzzo region, in Central Italy. The Punta Ferruccio cliff, characterized by conglomerate with notches, stands at a height of 25m, notch depth of 7m, and width of 4m, and serves as the focal point for the analysis. The research explores the impact of notches induced by basal erosion at the cliff and discontinuities, such as joints, on cliff stability. The numerical models of the cliffs are categorized into homogeneous material (without joints) and homogeneous material with joints.
