Abstract

Abstract. In Reina del Cisne (Cuenca-Ecuador), a dynamic sliding process occurred due to a cut made at the beginning of 2018 on the hillside without technical considerations for the construction of an access road to a house in the sector. From January 2019 to June 2019, the period analyzed in this work, the landslide caused complete structural damage to dwellings near the hillside and partial damage to houses farther away. It also led to the total collapse of the path that initiated the landslide. Field visits and comparisons using CloudCompare of point clouds obtained from UAV flights between January 2019 and June 2019 highlighted the high activity of this landslide. The analysis demonstrates the effectiveness of this technique for early detection of landslides, enabling timely warnings for inhabitants to take immediate measures to avoid disasters.
