Instituto Geofísico del Perú (IGP) reported that an average of 13 low-to-medium intensity explosions per day occurred at Sabancaya during 22-28 July. Gas-and-ash plumes rose as high as 2.3 km above the crater rim and drifted NE, E, and SE. There were eight thermal anomalies identified in satellite data. The report noted that the public should not approach the crater within a 12-km radius. Single explosions on 1 and 5 August produced an ash plume that drifted more than 30 km E and W, respectively.
