Abstract: The coastline between Tijuana and Ensenada is being subject to intensive development, mainly as resort property, and because of the roughness of the adjacent areas inland, the coastal area is used for the emplacement of public facilities such as water and gas pipelines, and public roads, on the surfaces of Quaternary developed terraces. At the same time a considerable segment of that coastline is subjected to land sliding. The seashore in the studied area is a jagged shoreline with alternating cliffs and beaches, the height of the seacliffs varies between 5 and 300 m. The area considered in this study outsets in Punta San Miguel to the north of Ensenada and extends approximately 40 km to the north to Valle El Descanso. The inland domain considered in this report varies according to the different conditions that characterized the region, with an area that averages 4 km in width. This study was conducted to delimit the presence of the landslides existent in the area, their cause and characteristics. As well as to propose mitigating actions in order to prevent future activation of these structures.
