Instituto Geofísico del Perú (IGP) reported that an average of 17 daily low-to-medium intensity explosions occurred at Sabancaya during 25 November-1 December.
Gas-and-ash plumes rose as high as 4 km above the summit and drifted NE, E, and S.
There were five thermal anomalies identified in satellite data, originating from the 240-m-diameter lava dome in the summit crater.
The Alert Level remained at Orange (the second highest level on a four-color scale) and the public were warned to stay outside of a 12-km radius.
