The Ituango Dam, an earth-core rock-filled dam currently under construction on the Caucariver (near Ituango town, Antioquia Department) it is at risk of collapse. Heavy rains and twotunnels collapsing as of 28 April, pose a high risk of failure of the earth embankment dam.Such a collapse could lead to catastrophic flooding downstream along the Cauca River.Preventive evacuations on many municipalities were ordered on Wednesday, May 16, andfive municipalities have been placed on maximum alert (Valdivia, Cáceres, Nechí, Tarazá,and Caucasia).The total number of inhabitants potentially affected by floodings following the dam collapse isestimated to be up to 120,000.The present map shows the flood delineation in the area of the Ituango Dam. The thematiclayer has been derived from post-event satellite image using a semi-automatic approach.The estimated geometric accuracy is 5 m CE90 or better, from native positional accuracy ofthe background satellite image.
