RVO reported that on 1 October field observations after an eruption at Manam confirmed lava flows in the NE valley.
There were two lava flow lobes, both stopping before inhabited areas; the smaller lobe flowed on the N side of the valley towards Koland Village and the larger flowed on the S side towards Boakure Village.
Effects from ash and scoria fallout on the NW and NW sides of the island were minor.
Based on analyses of satellite imagery and wind model data, the Darwin VAAC reported that on 3 October an ash plume rose 2.1 km (7,000 ft) a.s.l.
and drifted NW.
A thermal anomaly was also visible.
