Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosive activity at Sabancaya was similar to the previous week; there was an average of 41 explosions recorded per day during 9-15 October.
The earthquakes were dominated by long-period events, with fewer numbers of signals indicating emissions and hybrid events.
Gas-and-ash plumes rose 3.1 km above the crater rim and drifted more than 35 km S and SE.
The MIROVA system detected four thermal anomalies.
The report warned the public not to approach the crater within a 12-km radius.
