Etna (Sicily, Italy): At 7.41 am local time, an avalanche of brown ash could be seen originating from a point on the lower east flank of the New SE crater and descending several 100 meters towards the Valle del Bove.
While it looks as if a new vent opened, according to INGV Catania, it was a small landslide from the eastern flank of the SE crater and only involved cold material, without involving a new vent (which would have shown as hot thermal signals).
...9 Aug:
After little more than a week, another lava fountaining episode or paroxysm occurred from the New SE crater early this morning.
After a brief episode of ash emissions from the NE crater on 4 August, the volcano continued to be calm until yesterday, when first signs of a reawakening appeared in form of intermittent strombolian explosions at the New SE crater, along with fluctuating tremor with peaks reaching moderate values.

Fagradalsfjall (Reykjanes Peninsula, Iceland): The Icelandic Institute of Natural History(IINH), an agency of the Ministry for the Environment and Natural Resources, published a new model of the eruption so far, based on imagery collected 8 Aug 2021:

...9 Aug:
The eruption picked up again this morning after a pause of visible activity since yesterday afternoon. A new vent opened near the rim, but outside of the main crater, producing a small lava fountain and lava flow, observers noticed on webcam recordings.
According to Bjarki Kaldalón Friis from the Icelandic Meteorological Office interviewed by mbl.is, it is too early to say whether the new vent will replace the existing main crater over time or whether it should essentially be seen just a part of the same feature, i.e. a small side-vent from the upper conduit feeding the main crater.

Karymsky (Kamchatka): (9 Aug) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: VA IS NOT IDENTIFIABLE IN SATELLITE IMAGERY.

Shiveluch (Kamchatka): (9 Aug) The volcano continues to slowly extrude viscous lava, which adds to the volume of the lava dome in its crater and frequently generates smaller and sometimes larger incandescent rockfalls and smaller pyroclastic flows.
The latter have been generating frequent ash plumes that rose to up to approx. 4000 m altitude.
The perfectly smooth and symmetrically shaped spine known as "Dolphin-2" that had appeared in May earlier this year has by now mostly collapsed as the recent close-up image taken by our expedition leader Andrey shows who visited the volcano about 3 weeks ago.

Chirinkotan (Northern Kuriles, Russia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo 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 S direction.
The full report is as follows: VA CONTINUOUSLY OBS IN SATELLITE IMAGERY OBS VA DTG:09/1120Z to 12000 ft (3700 m)
...8 Aug:
A moderate explosion occurred at the volcano at 06:45 local time today as reported by the volcano observatory KVERT.
According to the Volcanic Ash Advisory Center (VAAC) Tokyo, an ash plume reached up to 9,000 ft (2,700 m) altitude and extended about 86 km to the west-southwest of the volcano.

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20210809/1209Z FL080 EXTD E OBS VA DTG:09/1200Z

Semeru (East Java, Indonesia): (9 Aug) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VONA STATE ERUPTION TO FL140 AT 08/2323Z OBS VA DTG:09/0550Z

Popocatépetl (Central Mexico): (8 Aug) The explosive eruption of the volcano continues at generally moderate levels.
Vulcanian activity continues from the summit crater producing moderate ash emissions up to 20,000 ft (6,100 m) altitude. Volcanic ash is dispersed towards the west-northwest and caused ash fall on the volcano's slopes. Incandescent bombs and blocks are being ejected at a short distance from the crater.

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 and is moving at 15 kts in SE direction.
The full report is as follows: continuous ash emissions to 24000 ft (7300 m)

Villarrica (Central Chile): (8 Aug) The volcano remains active. A near-constant incandescence continues to be observed in the summit crater indicating rise of magma inside the volcano's conduits detected by infrared cameras.
Glowing emissions of gas and steam accompany the activity.

Nevados de Chillán (Central Chile): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 and is moving at 5 kts in E direction.
