More and increasingly larger (and hence more dangerous) pyroclastic flows are being formed by the growing lava dome of the volcano. These "flows" are hot turbulent avalanches of hot blocks and ash in suspension with hot gas and air, that can travel down at great speed the slopes of the mountain, typically following the paths of valleys. ...more

The growing lava dome has started to produce (extremely dangerous) pyroclastic flows, as parts of the unstable mass of the viscous lava have now overtopped the crater the dome had been growing inside. ...more

The new lava dome of Sinabung (colored lines showing its extension on 24, 25, and 26 Dec) (VSI)
VSI confirmed that a new lava dome (a mass of viscous magma accumulating at the vent) has made its appearance on the northern crater of the volcano. It had a height of 56 meters and diameter of 105 meters on 26 Dec. Its volume was estimated to about 1 million cu meters, and the growth rate at 3.5 m3/second. ...more

Steaming Sinabung volcano this morning
The volcano has been relatively calm and only produced a steam plume sometimes mixed with ash, but no new significant explosions. Local media talk about a new lava dome spotted at the summit, but evidence (weak red glow at night and blurred photos etc) is still very weak and should be confirmed. ...more

Activity has been low at the volcano, but occasional small explosions and ash emissions still occur. VAAC Darwin reported an ash plume at 10,000 ft (3 km) yesterday and maintains Aviation Color Code RED, as the chance of a sudden larger explosion remains high.

Degassing from Sinabung volcano
No ash emissions have been detected during the past 48 hours, the crater shows only a degassing plume, but alert level remains at red, because new explosions could occur any time. The government has extended the emergency status until at least 21 December, which implies that the more than 17,000 evacuees remain in the total of 31 shelters. Their situation is difficult, with help needed in form of food, water, medicines and sanitary supplies. ...more
