Risk mapping for strategic planning of shelter response in Tijuana, Baja Califo…
Abstract
The city of Tijuana is located in a seis- mically active region due to its location on the boundary of the North Ameri- can and Paci c tectonic plates, with the presence of the Secondary System of the San Andreas Fault System that transmit the slip main movement be- tween the North American and Paci c plates. Under the current conditions of the city, future earthquakes represent an intensive risk; that would affect mostly the low-income population that lives in areas with high population density, in badly built houses, and on land with a higher exposure to risk.
The objective of this project is the preparation of a pre-disaster emergency shelter plan for earthquakes. The plan should ensure timely provision of roof; food and safety to people that have lost their houses. This report describes the methodology and criteria adopted for the selection, planning and activation of provisional shelters. A damage scenario for a 6.5 earthquake on the La Nacion fault 15 Km from the border of the U.S. with Mexico was selected for the preparation of the plan. Calculations for this scenario, through the simulation of RADIUS tool, indicate that 50,192 people would lose their houses and they would need emergency shelters.
The developed shelter plan has identified some areas and facilities that could be used for shelters provision. It includes a list of Junior-High-School buildings that might be used as a first option for provisional shelter, as long as an evaluation finds them structurally safe. Also, another list included parks and sport elds that are suitable as provisional shelters or for emergency
camps. The methodology developed in this study can be applied to other cit- ies in the country, given the expertise and skills and lesson learned from this project.
The results should be used to perform earthquake drills with the participation of authorities, institutions and the com- munity. This project promotes increased the seismic risk awareness of the com- munity and its leaders, with the aim of reducing risk to disasters, by incorpo- rating the various sectors of society.
