Collaborative Mapping for the Assessment of Seismic Vulnerability and Urban Resilience in Valdivia (Chile) ^†

The present work is part of the resilience study of urban areas, where the study area is the urban center of Valdivia (Chile). The aim is to catalog and identify buildings and urban blocks for the subsequent evaluation of exposure and vulnerability to seismic risk. This is done through a collaborative mapping with the participation of a local team of volunteers (of the Technological University of Chile INACAP) that was previously trained on vulnerability issues and OpenStreetMap platform. The study area comprises 83 urban blocks. Each urban block is subdivided into parcels, which contain buildings with different type of construction and different uses. In the future, this research will continue with the development of urban resilience indexes at physical and social scales.
