Sinabung volcano (Sumatra, Indonesia) activity update
Thursday Jan 02, 2014 12:25 PM | BY: T
The lava dome has now reached an estimated volume of more than 2.5 cubic million meters and a larger collapse could generate pyroclastic flows that reach considerable greater distance and destroy several villages, the Jakarta Post mentions.
According to Ahmad Nabawi from the Sinabung monitoring post, 22 eruptions had occurred on Wednesday from midnight to noon. "Fortunately, the nearest villages are not situated in the path of the lava [pyroclastic flows, ann.], so the villages are safe for now,” he continued, the Jakarta post cites. The nearest villages and most at risk include Bekerah, Simacem, Sigarang-garang and Suka Meriah.
According to the article, 19,286 people are currently evacuated from 23 villages within a 5 km radius and housed at 31 different shelters.
In the past two months, the eruption has (indirectly) caused the death of 11 people by breathing difficulties, depression, asthma attacks and hypertension, and hundreds of people suffer from illnesses related to inhalation of ash.
Continuous tremors can be felt in the area. Some believe that the continuous activity at the moment is a sign that the eruption will end soon. This might be true or not, but it seems that the volcano's peak activity is still ahead.

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. ...

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]

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]

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. [more]
