Summary: The disordered occupation in the Amazon, the population growth due the National Integration Plan and the lack of new techniques and technologies diffusion for crops management, economically accessible and less aggressiveness to the environment, resulted in the suppression of the natural forest in approximately 25% of the total area Of the Amazon. A factor associated with this suppression, due to its economic viability and local culture, the fire, is used for the conversion of forests to agricultural areas and the maintenance of previously established crops. In order to study this context, the present paper had as objective to identify the classes of land use and cover associated with the fire spots detected by satellites, also indicating burn recurrence areas for the municipalities of Santa Maria das Barreiras - PA, Colniza-MT And Porto Velho - RO.The results indicate that in the period from 2008 to 2014, 67% of the areas associated with the fire spots presented "Low" occurrence, associated mainly with the "Pasture" classes. There was an average loss of forest area of 7.2% over low recurrence areas, while in high recurrence areas there was an average loss of 22.5%
