Initially, based on the work and reports of official institutions, it is noted that the effects of the rupture of the dam on the environment have not yet been consolidated, since it is a recent fact, it requires the combination of efforts, the multidisciplinary work of the civil society institutions and government to better define these effects. The land use and landcover (LULC) maps presented the devastation resulting from this disruption. The mapping results indicate that approximately 496 hectares of dense forest were affected by the mud in the area defined in the study. In addition, 116 ha and 52 ha of herbaceous-shrub vegetation and bare soil, respectively, were suppressed by the breach. In relation to the LULC referring to urban areas, reforestation, pasture and agriculture, 19 ha, 18 ha, 7 ha and 1 ha were affected, respectively.
