Plumes drifted SE on 2 June and NW during 6-15 June. Ash fell in areas downwind between Yassa (WSW) and Baliau (NNW), and Warisi (ESE). Incandescent material was ejected from the crater, and roaring and rumbling noises were noted.
Pyroclastic flows on 16 June (at 0700, 0720, 0722, and 0729) channeled into the SE valley. The last pyroclastic flow was perhaps the largest as it reached the lowest elevation, 300-400 m above sea level, but was far from populated areas. Ash plumes from the pyroclastic flows drifted WSW and WNW; ash fell in Bogia (22 km SSW, on the mainland). Emissions from Main Crater were milder and mostly characterized by white and bluish plumes. Light gray plumes were noted during 2 and 8-9 June. Fluctuating incandescence was intermittently observed and ash fell in the NW part of the island.
