RSAM values on 6 November fluctuated between 250 and 360 units but began to increase around 14:30 and triggered alerts around 14:45. Values continued to increase and reached 400-500 units, heralding an eruption which began during 16:00-16:30. A gray ash plume rose 1 km and drifted northwest.
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 19:30, then declined and ceased during 21:00-22:00.
