Sinabung , Indonesia :
Level of Activity at Level 4 (AWAS). The Sinabung (2460 m altitude) from yesterday to this morning, was seen clearly, partially but generally covered by fog. The smoke emitted from the crater is not observed. The wind blows from south to southwest. Thanks to the seismographs, it was recorded 1 eruption / emission. Visually, the height of the column of ash can not be observed because the mountain is covered with fog. There were also recorded 46 landslides with a sliding distance of 500 to 1500 m, to the east, south-east and south.
Communities / visitors should not do activities within 3 km of the summit, and by sector, 7 km south-southeast, 6 km east-southeast and 4 km to North-east.
Deposits have formed a dam upstream on the Laborus River, people living in downstream river basins need to maintain vigilance because these dams can collapse at any time, creating downstream lahars / floods.
