The Sabancaya was the site of a strong explosion this 18.02.2017 from 6am. The ash plume exceeded 5,000 meters above the crater, then spread north-north-east. Ashes fall to Chivay, at 30 km from the volcano. The alert level is orange since December 2016, with an exceptional zone of 12 km around the Sabancaya.
