Instituto Geofísico del Perú (IGP) and Instituto Geológico Minero y Metalúrgico (INGEMMET) reported that an average of 15 explosions per day occurred at Sabancaya during 4-10 March.
Long-period seismic events were recorded, and hybrid earthquakes were infrequent and of low magnitude.
Gas-and-ash plumes rose as high as 2.8 km above the crater rim and drifted 20 km SW, W, and NW.
MIROVA detected four thermal anomalies, and on 3 March the sulfur-dioxide gas flux was high at 3,360 tons per day.
The report noted that the public should not approach the crater within a 12-km radius.
