The alert status for the volcano was lowered to Level 1 on 31 July.
The Rabaul Volcano Observatory (RVO) informed that minor gas and steam emissions rose from the volcano’s summit vent during 27 July-4 August. White plumes drifted about 11-12 km to the northwest of the volcano.
The seismic activity continues to fluctuate at moderate levels. RSAM values have been ranging from 380 to 800 related to an increase in volcanic tremor amplitudes between 15 July and 4 August.
Despite the lowering of the alert level, the local observatory warns that minor eruptive activity at the volcano may occur.
