Ash plume from a small pyroclastic flow at Sinabung yesterday
No significant changes in activity have occurred, although some local media reported apparently stronger (rock-fall and pyroclastic flow) activity over the weekend: The extrusion of viscous lava from the volcano's summit vent continues to feed the second lava lobe on the steep, upper SE slope of the volcano. ...more

Small pyroclastic flow at Sinabung this morning
A small pyroclastic flow occurred on the slope of the volcano this morning. The flow was confined to the slope of the summit cone and did not reach the devastated areas at the SE base. ...more

Evolution of the lava lobe at Sinabung volcano (VSI)
Seismic signals during the past weeks (VSI)
VSI published a new status report which indicates that effusive activity at the volcano still continues. The lava lobe still grows at very slow rate with an overall decreasing trend over the past months. ...more

Indandescents blocks from the second lava lobe that produced the collapse yesterday (image of unknown date: ANTARA FOTO/Irsan Mulyadi via Liputan6)
An unusually large collapse of parts of the still active lava flow occurred last night at around 19:30 local time and produced a large, dangerous pyroclastic flow that traveled approx. 4.5 km to the SE. There are no reports of injuries or fatalities, hopefully because no one was in the affected part of the exclusion zone. The flow had stopped in the immediate vicinity of the evacuated villages Berastapu and Sukanalu. ...more

Weak lava extrusion continues to add material to the viscous lava lobe, which at the same time looses some of its mass in occasional small rockfalls from its front and the sides. These sometimes result in small pyroclastic flows.

The possible ash plume from Sinabung and predicted trajectory (VAAC Darwin; MTSAT; annotations by @CultureVolcan / Twitter)
VAAC Darwin raised the Aviation Color Code to "Red" after a possible major ash plume was spotted on satellite imagery. According to the original report, a possible ash plume rose to estimated 50,000 ft (15 km) altitude 12:32 UTC on 22 May and drifted SW. The height was later reduced to 35,000 ft (12 km). ...more

Small pyroclastic flow at Sinabung on the morning of 13 May
Activity at the volcano remains weak. Slow lava extrusion continues along with occasional ash venting and small pyroclastic flows triggered by collapse of parts of the viscous lava lobe on the southern flank.

MODIS hot spots at Sinabung (MODVOLC, Univ. Hawaii)
The volcano continues to slowly aliment the large viscous lava lobe on the SE flank. Its growth is mainly manifested by numerous small to medium-sized rockfalls from its flanks and front, but also occasional pyroclastic flows that have reappeared since mid April. ...more

Pyroclastic flow on Sinabung yesterday (photo: Firdaus Surbakti - facebook.com/firdaus.surbakti)
A pyroclastic flow occurred yesterday afternoon (17:40 WIB) at the volcano. Most likely, it was triggered by a partial collapse of the steep lava tongue that had been emplaced on its southern flank during the past months. ...more

Evolution of Sinabung volcano's lava extrusion lobe (VSI)
Evolution of earthquake and rockfall activity over the past months (VSI)
Activity continues at the volcano in form of slow lava extrusion that feeds the thick lobe formed on the southern flank. Overall, the intensity of this activity continued to decrease. Authorities decreased the alert status from the highest (4) to 3 (on a scale of 1-4). ...more

Definition of a volcano
: A volcano is the term for any place on the surface of the earth, where hot molten rock (magma) reaches the surface.
: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
