Volcanic activity worldwide 8 Feb 2023: Etna volcano, Fuego, Popocatépetl, Merapi, Shiveluch, Karan...

Etna (Sicily, Italy): The volcano observatory in Catania released a bulletin for aviation services (VONA) mentioning that the effusive eruption (lava flow) at the summit craters has ended.
The volcano still shows unrest above background, but no other particular activity. Ash emissions are negligible.

Shiveluch (Kamchatka): (7 Feb) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20230207/1852Z FL220 REPORTED OBS VA DTG:07/2050Z

Chikurachki (Paramushir Island): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 9000 ft (2700 m) altitude or flight level 090 and is moving at 5 kts in NE direction.

The full report is as follows: POSS ERUPTION OBS AT 20230208/1120Z FL090 EXTD NE OBS VA DTG:08/1200Z to 9000 ft (2700 m)

Ebeko (Paramushir Island): (8 Feb) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20230208/0008Z FL140 EXTD S-E REPORTED OBS VA DTG:08/0010Z

Sakurajima (Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20230208/1534Z FL080 STNR OBS VA DTG:08/1530Z

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: EXPLODED AT 20230208/1506Z FL040 EXTD SW OBS VA DTG:08/1500Z

Karangetang (Siau Island, Sangihe Islands, Indonesia): A new eruption started at the volcano. Our local team on Siau island observed explosions, likely lava fountains, as well as a new lava flow with incandescent avalanches on the upper slope of the volcano.
More details will follow soon.

Merapi (Central Java, Indonesia): (8 Feb) A block-and-ash flow (hot avalanche of lava particles and ash) descended the southwestern flank of the volcano at 07:10 local time this morning, reaching approx. 1500 m sliding distance from the summit. It resulted from growing, more and more unstable hot lava material, accumulating in the active lava dome at the southwestern rim, making it prone to collapse into hot rock falls.
Ash plumes were separated from pyroclastic density currents (so-called phoenix clouds) that rose above the crater. The visibility of the event was very limited due to dense clouds.

The event was registered on a seismic signal with maximum amplitude of 52 mm and a duration of 130 seconds.

The seismic station registered continuous seismic activity (tremor and long-period/low-frequency earthquakes) hinting elevated fluid movements of gas, water and possibly magma under the surface.
A moderate ash fall has been reported in Manizales (Caldas).

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

Villarrica (Central Chile): (8 Feb) The elevated strombolian activity continues.
The mild short-term lava-fountaining episode (likely to be classified as paroxysm ) was at the progress at the volcano's summit crater on the night of 6 February. Incandescent lava jets, about 30 meters tall, were able to catch by local observers from Lod Nevados. Hot, juvenile and plastic scoria was reported landing onto the crater terrace area.

Preceded the paroxysm, three explosions occurred at the volcano in the time range between 07:40 and 07:42 PM local time.
The Volcanic Alert Level remains at Yellow with 500 meters exclusion zone around the main crater in place.
