This event is considered one of the greatest technoindustrial disasters in Brazilian history, placing in danger one of the largest hydrographic basin in Brazil: the São Francisco river basin. The search area comprises from where the sludge mud got in contact with the Paraopeba’s right bank to its mouth into the Três Marias Dam, adding up to approximately 315 km. For this monitoring the spectral band ratio method was utilized,  using images from the sensors MSI/Sentinel-2 and OLI/Landsat-8 captured at different dates, employing standardization of means and variances to harmonize the range of the surface reflectance values in each image.</p>}, journal={Ciência e Natura}, author={Freire, Neison Cabral Ferreira and Pacheco, Admilson da Penha and Queiroz, Vinícius D’Lucas Bezerra}, year={2022}, month={Jan.}, pages={e36} }
