Agung (Indonesia) - Report for 29 November-5 December 2017 - NEW

PVMBG reported that the eruption at Agung, which began on 21 November, continued during 30 November-5 December.
On 29 November gray ash plumes levels were rising to 2 km above the crater rim, resulting in ashfall to the SE.
During 30 November-5 December emissions continued to rise 2 km; most were white in color, but dense gray ash emissions were noted during 1-2 December.
Satellite data indicated that lava effusion continued at least through 1 December, and the erupted volume of lava was estimated to be 20 million cubic meters, equivalent to about a third of the total crater volume.
The base of the plume was often reddish during 29 November-5 December reflecting incandescence from lava in the crater.
BNPB noted on 5 December that 63,885 evacuees were distributed in 225 evacuation shelters.
Lahars were first noted on 21 November and continued to be observed through 5 December.
The lahars flowed down drainages on the S flank (along the Tukad Yehsa, Tukad Sabuh, and Tukad Beliaung drainages) and also down the Tukad Bara drainage on the N flank, impacting houses, roads, and agricultural areas.
The Alert Level remained at 4 (on a scale of 1-4), and the exclusion zones continued at a general 8-km radius and 10 km in the NNE, SE, S, and SW directions.
