Etna (Sicily, Italy): The volcano's New SE crater has become more and more active over the past few days, and started to show weak strombolian activity of varying intensity since yesterday morning. This activity produces occasional ash emissions which are rapidly dispersed in the summit area.
Over the past days, volcanic tremor amplitude has been showing continuous oscillations, with an overall gradually increasing trend, reaching high values during the past 24 hours. According to the volcano observatory, the source of the tremor - corresponding to the area of magma movement - is located under the SE Crater area at an elevation of 2800-2900 m above sea level, or 300-400 m below the crater rims.

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

Asama (Honshu): The activity of the volcano continues to be elevated since 15 March as the increase of seismic activity and slight inflation have been recorded.
Continuing gas-steam emissions were observed by surveillance cameras starting about 18:22 local time today as can be visible in the attached video below. This may indicates elevated fluid movements of gas, water and possibly rising magma under the surface, typical signs for an upcoming eruption.

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20210609/1706Z FL060 EXTD NW OBS VA DTG:09/1700Z

Lewotolo (Lesser Sunda Islands): The volcano continues to produce occasional strombolian activity.
The explosive eruption occurred from its crater at 18:50 local time yesterday accompanied by ejected scoria that caused incandescent avalanche onto the SE flank at about 500 m distance from the summit.

Krakatau (Sunda Strait, Indonesia): (9 Jun) The local observatory reported that gas-steam plumes containing some amount of ash occurred from the volcano on 6 June.
Plumes rose 100 m-150 m above the summit.

Semeru (East Java, Indonesia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 40000 ft (12200 m) altitude or flight level 400 and is moving at 10 kts in SW direction.
The full report is as follows: HIGH LEVEL ERUPTION TO FL400 OBS VA DTG:09/1500Z to 40000 ft (12200 m)

White Island (New Zealand): An elevated volcanic tremor was recorded on 1 June starting about 04:00 local time that lasted approx. 2 hours.
During this period, no impulsive acoustic signals were recorded, unlike previous episodes characterized by small explosive events and rapidly returned to typical low levels.

Great Sitkin (United States, Aleutian Islands): (8 Jun) An aerial imagery of the Alaska Volcano Observatory (AVO) from 30 May confirmed a lahar (mud flow) which traveled from the summit crater. The lahar likely formed as a lava flow melted snow and caused this volcanic mud flow.
Fresh ash deposits on the right snow covered flank are visible in the attached image as pyroclastic flows were triggered by the latest explosion on 25 May.

Sangay (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 .
The full report is as follows: VA CLDS OBS IN STLT IMAGERY to 20000 ft (6100 m)

Reventador (Ecuador): 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: FRQ VA EMS to 15000 ft (4600 m)

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 and is moving at 25 kts in E direction.
The full report is as follows: continuous ash emissions to 21000 ft (6400 m)

Nevados de Chillán (Central Chile): The effusive-explosive eruption of the volcano continues and has remained essentially unchanged at modearte levels.
Two lava flows remain active and continue to effuse from the summit crater onto the N-NE flanks at moderate discharge rate.
