Volcanic activity worldwide 7 Sep 2021: Fuego volcano, Karymsky, Popocatépetl, Shiveluch, Ibu, Reve...

Karymsky (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 10000 ft (3000 m) altitude or flight level 100 and is moving at 15 kts in SW direction.
The full report is as follows: VA AT 20210907/1220Z FL100 EXTD SW OBS VA DTG:07/1220Z to 10000 ft (3000 m)

Shiveluch (Kamchatka): (7 Sep) After almost one month of the intense explosive-effusive eruption of the volcano, it seems that the activity decreased significantly over the past few days as reported by Alexey Demyanchuk from the local observatory.
Incandescent avalanches that have accompanied the elevated activity at the volcano, are no longer active and only rare glowing rock falls are being rolled down to the slopes from the crater rim.

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20210907/1545Z OVER FL090 STNR OBS VA DTG:07/1540Z

Ibu (Halmahera, Indonesia): (6 Sep) 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 and is moving at 10 kts in NE direction.
The full report is as follows: DISCRETE VA TO FL070 AT 06/2250Z EXT NE OBS VA DTG:06/2250Z to 7000 ft (2100 m)

White Island (New Zealand): (7 Sep) Continuing ash emissions observed at the volcano on the last week, have now decreased as published by the GeoNet New Zealand.
The constant glow is visible from the summit crater at night indicating high-temperature gas emissions.

Satellite based ground deformation measurements continue to show a broad region of subsidence around the active vents. This may be attributed to the release of pressurised gas at depth which has fed the recently observed plumes. It is likely that weak wall fragments fall into the gas stream through the active vents, leading to the reported ash emissions.
Volcanic Alert Level remains at level 2 and the Aviation Colour Code remains at Yellow.


Semisopochnoi (United States, Aleutian Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Anchorage warned about a volcanic ash plume that rose up to estimated 12000 ft (3700 m) altitude or flight level 120 and is moving at 15 kts in NNE direction.
The full report is as follows: LAST ERUPTION WAS 18Z. VA IS NO VISIBLE IN SATELITE BUT CAMERA AND RECORDERS SHOW ANOTHER ERUPTION HAS to 12000 ft (3700 m)

Popocatépetl (Central Mexico): (7 Sep) The explosive eruption of the volcano continues at moderate levels.

On 4 September at about 13:00 local time, a dense dark ash plume reached approx. 20,000 ft (6,100 m) altitude and drifted NW. Another eruption occurred today at 08:22 local time as the volcano sent ash column to 19,000 ft (5,800 m) height.
The seismic network recorded 466 minutes of low amplitude internal tremor associated with near-constant vulcanian explosions
