The Pelluhue country was one of the most affected during the earthquake and tsunami of February 27, 2010 in central Chile, with 47 deaths, the highest number of per-capita deaths in the country. This study is oriented to analyze the resilience of the urban centers of the commune, from its principal instances: preparation, resistance, recovery and adaptation. The damage generated by the tsunami is studied through an on-site survey, supplemented by surveys conducted in 2013 and 2015, a safety perception consultation and an analysis of the impact of territorial planning instruments in the rehabilitation of urban centers. From these studies it is concluded that the commune experienced a rapid infrastructure recovery between 2010 and 2012. The modifications incorporated in the ordinance of the Community Regulatory Plan at the end of 2012 promoted the use of a new structural typology adapted to the tsunami risk in the Coastal Tourist Zone (ZTBC-1). The use of wood and concrete structural frames on the first floor was adopted in response to the low coefficient of soil occupation suggested in the ordinance of the Community Regulatory Plan for that area, without necessarily complying with structural design criteria. However, in some other areas, within the flooded area, it was rebuilt without adopting adaptation criteria. Even when a consultation was implemented, which does not have adequate representation of the entire population, the survey indicates that the emergency plan implemented by ONEMI, in turn, generated a better perception of safety in the risk areas by residents, but visitors are unaware of the current evacuation measures.
