Background: There is a growing interest in identifying, monitoring and evaluating the impact of agricultural and forest fires due to social, environmental and economic impacts. Methodology: This article addresses the characterization of the burned areas in the districts of the department of San Vicente, El Salvador Central America, using multispectral images for atmospheric and geocolor penetration with Sentinel 2, as well as the application of the NBR index for the identification and validation of the burned areas during the period from January 1 to April 15, 2024. Results: it was possible to determine that NBR values close to 0 show areas without vegetation, mainly plots in preparation prior to planting, values of -0.27 show recently burned areas and NBR values of -0.75 to -0.80 indicate hot
spots or fires that were registered at the time. Conclusion: it was possible to determine the fires attended in the district of San Esteban Catarina with an area of 2.56 km2
and in the district of Apastepeque, with an area of 3.7
km2 and heat points of 0.07 km2 among other areas, mainly in protected natural areas. In this way, a baseline is generated as a tool for community resilience and decision-making by key institutional actors, allowing work to
strengthen governance, risk reduction, adaptability, community participation and emergency preparedness and response as key axes of resilience.
