Abstract. In Reina del Cisne (Cuenca-Ecuador) a dynamic sliding process was created due to a cut that was applied at the beginning of the year 2018 to the hillside without technical considerations for the construction of an access road to a house in the sector. From January 2019 to June 2019, period analyzed in this work, the landslide has caused total structural damage (dwellings near the hillside) or partial (houses away from the hillside) and the total collapse of the path that caused the landslide. The field visits and the comparison with CloudCompare of the clouds of points obtained by flights of an unmanned aerial vehicle, UAV between the months of January 2019 and June 2019, have highlighted the high activity of this landslide. The resulting analysis clearly presents the applicability of this technique for early detection of landslides.
