Fires are the cause of the devastation of thousands of hectares of ecosystems on the planet, generating impacts on public health, economic and environmental losses. The present study aims to perform a temporal analysis of the heat sources detected in different uses and land cover mapped between 2008 and 2018 in the hydrographic basin of the Munim River, eastern Maranhense. The data used in the study were obtained from the digital platform of the National Institute for Space Research (INPE). The number of outbreaks recorded came from the TERRA, AQUA, GOES, NOAA, MSG-02 and ERS-2 satellites. A total of 74,752 outbreaks in the basin area were found between the years 2008 to 2018, with November as the most critical month, with 30.33% of total outbreaks, followed by October with 23.03%, a period in which there is practically no rainfall in the region. It was found that the year 2015 was the one with the highest rate of outbreaks with 14,025 occurrences and that the year 2011it was the least expressive, with 2,116 occurrences.
