Due to the contributions of accumulated water, an avalanche of great proportions occurred that affected farms, stables, houses and generated severe erosion on the banks of the Granados River.
The main materials dragged downstream consisted of mud, rocks, and large tree trunks, which were deposited in the flatter parts or discharge areas located in the middle section of the channel. It is estimated that the volume of material detached approximates 500,000 cubic meters. This volume was increased due to the incorporation of materials caused by the drag of the mass downslope.
