A large landslide hit the Caylloma Province, Peru at around 07:30 LT on May 9, 2021, blocking the Colca River in the district of Chivay and forming a natural dam.
The landslide took place close to the city of Chivay and is about 300 m (985 feet) long.
Authorities estimated the river is blocked by at least 800 m3 (28 250 feet3) of rock and earth, and ordered the clearing of the debris to drain the accumulated water.
There are no reports of the affected population.
