Stromboli (Eolian Islands, Italy): The visual activity at the volcano remains at typical low to moderate levels, characterized by weak to moderate strombolian explosions mainly from the NE vent, as well as spattering and puffing from other vents in the crater terrace.
Internal activity parameters are elevated, resulting in an overall HIGH volcanic activity index on the scale developed by the Experimental Geophysical Laboratory of the University of Florence (LGS):

Etna (Sicily, Italy): The volcano continues to produce spectacular strombolian-type explosions involving several of its summit craters.
Protagonist of this activity remains the New SE crater with two active vents, followed by less-intense activity at the Voragine and occasionally Bocca Nuova central craters.

Klyuchevskoy (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 and is moving at 15 kts in W direction.
The full report is as follows: VA CONTINUOUSLY OBS IN SATELLITE IMAGERY OBS VA DTG:03/1720Z to 20000 ft (6100 m)

Sakurajima (Kyushu, Japan): (3 Feb) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 5000 ft (1500 m) altitude or flight level 050 and is moving at 25 kts in SE direction.
The full report is as follows: VA AT 20210203/0050Z FL050 EXTD SE OBS VA DTG:03/0050Z to 5000 ft (1500 m)

Suwanose-jima (Ryukyu Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 4000 ft (1200 m) altitude or flight level 040 and is moving at 15 kts in SE direction.
The full report is as follows: VA AT 20210203/1220Z FL040 EXTD SE OBS VA DTG:03/1220Z to 4000 ft (1200 m)

Raung (East Java): (3 Feb) The explosive activity of the volcano continues at elevated levels since 21 January as the alert level was raised to "orange".
The volcano generates near-constant emissions of ash, gas and steam from the summit vent that rose to estimated 14,000 ft (4,300 m) altitude. Volcanic ash is dispersed towards the east and south.

Dukono (Halmahera): (3 Feb) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA REPORTED TO FL050 MOV S AT 03/0118Z OBS VA DTG:03/0135Z

White Island (New Zealand): (3 Feb) Over the last year, a series of thermal infrared images have been regularly collected by helicopter to observe the temperature of steam and gas vents as reported GNS volcanological observatory. Temperatures have shown a gradual decline since the December 2019 eruption, from over 700 °C in February 2020 to 300 °C on 21 January 2021. The gas emission temperatures are now similar to temperatures measured in July 2018.
During January 2021, GNS Science continued monitoring of Whakaari/White Island by observation flights and measurement of gas emission rates, and with automatic earthquake, camera and ground deformation observations. Recent observations confirmed no evidence of recent eruptive activity, or signs of collapse in or near the active vents. There is little water ponded on the floor of the 1978/90 Crater.

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 19000 ft (5800 m) altitude or flight level 190 .
The full report is as follows: CONS LGT VA EMS. to 19000 ft (5800 m)

Pacaya (Guatemala): The volcano continues to effuse the lava flow on the southwest flank at moderate levels.
Frequent glowing rockfalls from the lava flow tumble down to the slopes and caused avalanches of incandescent material visible in the attached video below.
