Sinabung volcano (Sumatra): eruption news and activity updates

The eruption, characterized by slow extrusion of viscous lava, continues well into its second year. During the past days, incandescent avalanches, but also explosions (from pressurized gas-rich magma) have occurred, producing small to moderate ash plumes rising up to 2-3 km.

Moderately large pyroclastic flow from Sinabung on 15 Dec 2015 (photo: Endro Lewa)
The volcano continues to slowly extrude viscous lava that builds up the active dome with several overspilling lava lobes. As parts of these break off now and then, small to moderately large pyroclastic flows are being generated from time to time.

Explosion and pyroclastic flow at Sinabung on 31 Oct at 14:45 local time (image: Theger BM)
During the past days, explosions and pyroclastic flows - often occurring together - triggered by collapses of the lava dome have been more frequent and more intense than during most of the past months. ...more

Ash plume from Sinabung yesterday (image: @BeidarSinabung / twitter)
Explosions and pyroclastic flows continue to occur at the volcano during the past days. This morning, a pyroclastic flow traveled 2 km and produced an ash plume of 2.5 km height.

The volcano continues to slowly extrude viscous lava, which results in occasional small to moderately sized pyroclastic flows (2-3 per day on average). ...more

PVMBG reported that during 21-28 September foggy weather sometimes prevented visual observations of Sinabung and the growing lava dome in the summit crater. Lava flows on the flanks were incandescent as far as 3 km E to SE. As many as five pyroclastic flows per day were detected, traveling as far as 4 km ESE. Ash plumes rose as high as 4.5 km. ...more

Pyroclastic flow from Sinabung this morning at 08:36 local time (image: #SadrahPS / twitter)
Several pyroclastic flows, some relatively large, have occurred over the past days. While the slow effusive activity itself has not significantly changes, the lava dome and its viscous lava lobes that spilled over onto the steep upper flanks are now undergoing a phase of increased collapses due to increased instability.
