The overall objective of this project is to produce maps identifying potential landslide hazard areas in the city of Ensenada, Baja California Mexico. In this paper we present the results of the granulometric analysis for 7 soil samples of different sites in the city that are subject to landslide or rock displacement hazard. We also present the tests done on the physical sliding model and a comparison between the sites and the model observations. The results show some consistency between the sliding model and the field observations. Keywords: landslides, physical modelling, natural hazards. 1 Introduction Landslides are known for its fierce consequences in the number of deaths. In Brazil, more than 500 people were reported to have died after torrential rains triggered mud avalanches in Teresopolis and neighbouring areas north of Rio de Janeiro; some of the areas were illegally occupied by houses built by their occupants on steep hillsides. In Oaxaca, Mexico, on the 28th of January of 2011, a landslide devastated the State, mainly the town of Santa Maria Tlahuitoltepec leaving approximately 1500 houses with damages and 25000 victims [1].
