Instituto Geofísico del Perú (IGP) reported that an average of eight daily low- to medium-intensity explosions occurred at Sabancaya during 6-12 January.
Gas-and-ash plumes rose as high as 3 km above the summit and drifted NE, E, and SE.
There were six thermal anomalies identified in satellite data, originating from the 282-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.
