The volcano continues to effuse a viscous lava lobe from its summit crater. Frequent rockfalls and pyroclastic flows occur due to partial collapses of the sticky lava masses on the steep upper slope. Our friend Bastien Poux who has been observing the volcano during the past weeks sent us the following report:
"I have been watching the Sinabung volcano for the last two weeks, there is a big lava lobe hanging at the summit, you can see it glow at night.
Debris flows are getting bigger and more frequent, usually the rocks come form the side of the lobe, where it is contact with the walls made of older formations (sign the the lobe moves forward), between 10 and 25 times a day, going down the flank to distances between 500 and 2000m in general, couple of them went to 3000m yesterday when a big piece of the frontal part of the lobe collapsed. There is still a 5km forbidden perimeter, more or less respected by the people who want to go back in their houses after being refugees for 18 months."
