Hillside instability in the Tijuana metropolitan area. Analysis of landslide-provoked building collapse

We analyses the main causes of landslides in the Tijuana metropolitan area (Baja California, Mexico) and discuss the conditioning and triggering factors affecting land instability in the region. The case of a landslide occurred in a neighbourhood of the city, which affected several buildings, and study to investigate its causes is presented. The study included the analysis of static and dynamic stability and the calculation of safety factors. Analysis of the causes of land instability in the region and this particular case study enabled us to draw conclusions regarding the natural and anthropic factors with the greatest bearing on landslides occurring in the city and to make recommendations for non-structural actions and measures aimed at reducing the risk of damage to the land and buildings.
