Indonesian giant Sinabung produces a series of glowing avalanches and pyroclastic flows in the last 24 hours, which reach a length of 1.5-3.5 km.
The cause of this powerful phase of the eruption was probably of viscous lava that spills from the summit of the dome in the steep ravine of the upper flank, now become unstable.
Recall Sinabung again “back to life” in August 2010, Since then it has claimed the lives of at least 25 people on the Indonesian island of Sumatra.
After the collapse of the powerful pyroclastic flow that devastated the village of Gambero 21 may this year and killed 9 people, a new lava dome grows on the giant. In March due to the violence of the giant had closed the local school within a radius of 7 km from the mountains, the buildings of some schools damaged.
