Phase: Phase 4: Action Plan

Institutions: Ministers: Infrastructure, Urban & Housing and Universidad de Atacama

Sector: Urban

Public Policy : Plan Regional de Ordenamiento Territorial (PROT)

Countries: Chile


Chile recently started a decentralization process of land-use planning towards regional authorities, which included the formulation of regional land-use plans (“Plan Regional de Ordenamiento Territorial” or PROT). In this context, the Government of Chile requested support to The World Bank to develop probabilistic seismic and tsunami risk assessments for the Atacama Region, and to build institutional capacity with the ultimate goal of incorporating risk related information in land-use planning strategies.

To do so, the Bank and the Government of Chile implemented a Technical Assistance Project (TAP) under which the Atacama Regional Government, the University of Atacama and the Sub-Secretariat for Regional Development and Administration (SUBDERE) strengthened their capacity to generate hazard modeling information. The TAP resulted in the development of a seismic hazard model for the cities of Copiapó, Caldera and Tierra Amarilla, and a tsunami hazard model for the coastal zone of Atacama, which successfully informed the PROT for Atacama. The intervention in Chile also included the development of a pilot damage assessment in one of the most affected areas after the 8.8 Mw earthquake on Februrary 27, 2011 (city of Constitución and surrounding areas) and the delivery of recommendations for the integration of disaster risk reduction considerations into land-use planning strategies at a regional level.
