This paper uses combined remote sensing and advanced numerical modeling methods to investigate the intact rock fracturing that occurred prior to and during the 2014 San Leo landslide (Northern Italy). Numerical analyses showed that erosion of clay-rich materials at the base of the slope drives the brittle propagation of fractures within the rock mass. The progressive formation of a fully persistent rupture surface was simulated, resulting in the detachment and toppling of fault-bounded rock columns. This study highlights the potential role of intact rock fracturing on slope kinematics, and the interaction among intact rock strength, structural geology, and slope morphology. View this paper
