Chilean heritage areas were the most affected after the 2010 earthquake (8.8 in Richter scale), mainly due to poor maintenance and scarce funding, but also because of applied reconstruction approaches. Among the decisions that produce more impact in them and in the long-term re-construction, are the emergency actions made just after the disaster, such as indiscriminate demolition and the application of money vouchers given directly to the inhabitants. This will be shown through the cases of Chanco and Paredones, in order to explore how it is possible to improve these actions by offering technical support in the right timing.
