The full report is as follows: DISCRETE VA EMISSION OBS TO FL060 AT 12/2340Z MOV SE to 6000 ft (1800 m)

Sinabung (Sumatra, Indonesia): (13 Dec) Surveillance cameras observed an incandescent avalanches of the dome blocks that slid down along the E-SE flank of the volcano with distance probably of 1,000 m from the summit.
Partially gravitational collapse of the lava dome in the inner summit crater continues to generate block-and-ash flows.

The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 3 km distance from the main crater and 5 km on the SE flank and 4 km on the NE flank.


Dukono (Halmahera): (12 Dec) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 .
The full report is as follows: CONTINUOUS VA EMISSION OBS TO FL070 AT 12/2310Z MOV SE to 7000 ft (2100 m)

Santiaguito (Guatemala): (13 Dec) The activity at the volcano increased since 11 December characterized by moderate-to-strong pyroclastic flows as INSIVUMEH reported.
Actively growing lava dome causes generating the block-and-ash flows likely caused by partially gravitational collapse of the Caliente lava dome.

Pacaya (Guatemala): (13 Dec) It seems that a new eruptive fissure vent opened on the W-NW flank, as reported by the volcano observatory INSIMUVEH. A length of a new lava flow is approx. 50 m-250 m.
Another, second eruptive fissure vent branched off into three lava flows on the southwestern slope remains active, currently about 400 m-600 m long.

The activity of the volcano has been significantly effusive during the past few months including irregular intervals of strombolian-type explosions. Incandescent material is being ejected to an approx. height of 175 meters above the crater and 50 m distance from the crater associated with near-constant degassing. An ash plume rose 656 ft (200 m) above the summit.
It is not recommended to approach the both lava flows due to high temperatures as the warning bulletin states.


Fuego (Guatemala): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 .
The full report is as follows: DECR ACT to 15000 ft (4600 m)

Reventador (Ecuador): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA NOT OBS

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 24000 ft (7300 m) altitude or flight level 240 .
The full report is as follows: continuous ash emissions to 24000 ft (7300 m)
