Abstract

The vulnerability of a total of 227 buildings associated with tourism in the port city of Valparaíso, which is located in the flood area defined for the worst known scenario for the area, was identified and evaluated. The Papathoma Tsunami Vulnerability Assessment Model (PTVA-3) was used. The results show that the buildings were associated with accommodation, have low vulnerability indexes, it is recommended to consider vertical evacuation in these cases. The other typologies-restaurant, sight and services-also have low vulnerability indexes, but with greater dispersion. The port and the railway line have been transformed into a barrier of protection and exclusion of building sites in the most exposed areas. Sectors that remain outside the railway line, such as Caleta Portales and Muelle Barón, show the highest vulnerabilities.
