Sinabung and Agung activity.

The Sinabung made its show yesterday 24 October.
Many pyroclastic flows have been recorded by the webcams and the faithful observers of the volcano.
Without being exhaustive, here are some moments when they were observed: at 10:05, 14:45-51, 19:19, 20:40, 22:14-30.

The summit lava dome remains impressive; the latest measurements taken on October 12 are around 2.2 million cubic meters.

The dam created on the Laborus River, following the successive pyroclastic flows of April 10, 2017 and August 2 and 3, 2017, resulted in the formation of a growing reservoir lake; it is not sufficiently strong to contain such a volume of water and is a risk of lahar or flash floods not insignificant.

Seismicity continues to decline at Agung.

On October 24th, the PVMBG reported 2 episodes of non-harmonic tremor, 133 VA deep volcanic earthquakes, 131 VB superficial volcanic earthquakes, 7 local tectonic earthquakes and 2 more distant tectonic earthquakes, including an important magnitude 6.5 recorded in the sea. Banda, this 24.10.17 at 10:47 UTC and a depth of 550 km.
 
This morning, the summit was clear and fumaroles light.
The BNPB still reports 138,000 inhabitants still displaced.
