Klyuchevskoy (Kamchatka): (12 Jan) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20210112/0445Z FL200 REPORTED OBS VA DTG:12/0450Z

Sakurajima (Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: EXPLODED AT 20210112/1409Z OVER FL070 EXTD E OBS VA DTG:12/1400Z

Dukono (Halmahera): (12 Jan) 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 MOV N OBS VA DTG:12/0050Z to 7000 ft (2100 m)

Popocatépetl (Central Mexico): (12 Jan) Over the past weeks, the activity of the volcano has remained essentially unchanged at moderate levels.
It is characterized by occasional vulcanian-type explosions (0-3 per day) and 27 passive emissions of steam, gases and small amounts of ash recorded yesterday. The plumes were dispersed towards the east-northeast direction.

At the end of December 2020, daily volcanic tremor duration increased to approx. 1000 min / day around which value it has been fluctuating during the past two weeks. The highest volcanic tremor during this period reached value 1410 minutes on 5 January as can be seen in attached diagram.
This event as well as near-constant emissions of gas and small amounts of ash suggest continued rise of fresh magma probably accumulating as a new lava dome in the inner summit crater.


Fuego (Guatemala): The explosive eruption of the volcano has remained essentially unchanged at moderate to high levels. No significant change in activity has occurred since the last update.
Ongoing moderate-to-strong strombolian-to-vulcanian activity continues from the summit crater at regular intervals of 9 to 12 per hour showering the summit cone with glowing lava bombs. Incandescent material is being ejected to an approximate height of several hundred meters above the crater and caused moderate to strong avalanches of material as can be seen in the attached video.

Plume of ash rose to an estimated altitude of 4,700 ft (15,420 m) and extending about 15-20 km to the NW of the volcano.

...12 Jan:
No significant change in activity has occurred during the past weeks. The effusive-explosive eruption of the volcano continues.
The explosive activity continues from the active crater with near-constant ash emissions that reached 14,300 ft-14,900 ft (4,360 m-4,560 m) altitude and drifted into W direction.

Incandescent blocks slid down along the flanks and caused avalanches of material.
The lava flow on the northeast flank remains active.


Sabancaya (Peru): Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: UNABLE TO DETECT
