Explosion and pyroclastic flow from Sinabung yesterday
The volcano's eruption continues with increasing and more and more frequent (every 15 minutes) explosions and pyroclastic flows from the growing lava dome. Ash plumes have been reaching 20,000 ft (6 km) altitude, run-out lengths of the pyroclastic flows approx. 2-3 km.

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. ...
