In Brazil, using fire for ground cleaning is heavily present in the culture of the countryside communities. However, this practice is a crime if done without authorization from competent authorities and may cause large areas of destruction when fire runs out of control. In order to fight these fires, there are monitoring systems able to detect with relative precision the occur- rence of fires that assists authorities, for example, IBAMA (Brazilian Institute of Environment and Renewable Natural Resources), helping to fight this practice and to punish those responsible for the fires. In this context, this work proposes the execution of computational analysis of data collected about forest fires in the last years, transforming them into useful information through an Exploratory Data Analysis. Through this, we hope to identify the advance of forest fires in the previous years in the State of Tocantins, which belong to the area designated as Amazônia Legal(area that comprehends the totality of the Acre, Amapá, Amazonas, Mato Grosso, Pará, Rondônia, Tocantins states and part of Maranhão state), on the way to turn it into useful infor- mation through the Exploratory Analysis technique. This work seeks, then, to comprehend the magnitude of the advance in fires in the last years on this territory, just like the causes of such, and to highlight possible actions to reduce the amount of fire and to make knowledge available for use in future studies. For doing this, there will be used data showing the amount and location of the fires provided by INPE (National Research Institute) and meteorological data about the Amazônia Legal territory provided by INMET (Meteorology National Institute)
