The mesoregion of Sertão Pernambucano presents climatic conditions that directly affect agricultural production, since it presents a warm, dry climate and irregular rainfall regime. Due to these characteristics, the predominant biome of the region is the Caatinga, which has been suffering over the years with various anthropic actions, including besides deforestation, fires. In order to map and monitor the incidence of hot spots in this mesoregion during the ten year period (2010-2017), this article aims to identify and characterize the profile of these burn scars, aiming to follow the process of regeneration of the plant surface. Based on the results of the digital processing of the satellite images and the vector files of heat sources in the WEKA Data Mining Software, a correlation of 0.8153 was found when crossing the NDVI index data at the time of burning and after such event, where also, these areas susceptible to fire showed a direct link to precipitation prior to the burn event. Such pixels varied in a spectral range of NDVI between 0.25 and 0.44. When the natural recovery capacity of the vegetation in the field after the burn event was evaluated, the most important parameters were: precipitation and NDVI index, both after burning. From a correlation between these values of 0.7264, it was observed that such a process would only occur if two criteria were met: a critical precipitation of 32.25 mm and a posterior minimal NDVI index of 0.39.
