                         environmental satellites and their relationship with 
                         socioenvironmental factors and meteorological systems in the state 
                         of Alagoas, Brazil. Data considered the period between 2000 and 
                         2017 and was obtained from CPTEC/INPE. Annual and monthly analyzes 
                         were performed based on descriptive, exploratory (boxplot) and 
                         multivariate statistics analyzes (cluster analysis (CA), principal 
                         component analysis (PCA)) and Poisson regression models (based on 
                         2000 and 2010 census data). CA based on the Ward method identified 
                         five fire foci homogeneous groups (G1 to G5), while Coruripe did 
                         not classify within any group (NA); therefore, the CA technique 
                         was consistent (CCC = 0.772). Group G1 is found in all regions of 
                         Alagoas, while G2, G5, and NA groups are found in Baixo S{\~a}o 
                         Francisco, Litoral, and Zona da Mata regions. Most fire foci were 
                         observed in the Litoral region. Seasonally, the largest records 
                         were from October to December months for all groups, influenced by 
                         the sugarcane harvesting period. The G4 group and Coruripe 
                         accounted for 60,767 foci (32.1%). The highest number of fire foci 
                         occurred in 2012 and 2015 (between 8000 and 9000 foci), caused by 
                         the action of the El NiñoSouthern Oscillation. The Poisson 
                         regression showed that the dynamics of fire foci are directly 
                         associated with the Gini index and Human Development Index (models 
                         1 and 3). Based on the PCA, the three components captured 78.8% of 
                         the total variance explained, and they were strongly influenced by 
                         the variables: population, GDP, and demographic density. The 
                         municipality of Macei{\'o} has the largest contribution from the 
                         fire foci, with values higher than 40%, and in PC1 and PC2 are 
                         related to urban densification and population growth.",
