Manam (Papua New Guinea) - Report for 6 November-12 November 2019 - NEW

RVO reported that at 1330 on 2 November a single large explosion at Manam generated a dense dark ash plume that rose 1 km above the summit and drifted NW.
A shock wave was felt at the Bogia Government station (about 40 km SE) about 1 minute later.
RSAM values on 6 November fluctuated between 250 and 360 units but began to increase around 1430 and triggered alerts around 1445.
Values continued to increase and reached 400-500 units, heralding an eruption which began during 1600-1630.
A gray ash plume rose 1 km and drifted NW.
Incandescent material ejecting from the vent was visible at the start of the eruption and became more visible as the evening grew darker.
The eruption peaked in intensity around 1930, then declined and ceased during 2100-2200.
