This paper deals with the monitoring of a slope of land under landslide risk in the Serra de São Geraldo, in the Zona da Mata Mineira. Anterior indications were taken during earthmoving work to repair deformations on a stretch of road that runs through Serra. The work was monitored by a second network of points located near the cracks detected in the soil, at three different times; this was made using a network of support, installed in an area that was not affected by slip assumption. In order to collect data it was used conventional survey associated with trigonometric leveling with total station and GPS survey. After adjustment of observations and the processing of the network, the ground shifts were identified. Through the analysis it was possible to identify displacements with values between 1 and 281 mm and with the aid of geostatistics it was possible to assess the spatial dependence of movements for periods of 50 and 61 days. Finally, displacement maps were generated using Kriging.
