Map of today's active volcanoesEtna (Sicily, Italy): An earthquake of magnitude 3.9 hit below Etna's eastern flank this morning at 08:49 local time at a shallow depth of only 4 km and was felt in nearby towns such as Zafferana, Santa Venerina, and Milo.No immediate change in volcanic activity has been detected, although such events, even if originally tectonic in nature, can trigger underground movements of magma. Interestingly, the volcano's seismic activity has been picking up lately: already 3 days earlier, on 18 Oct 2026, an earthquake swarm occurred under the volcano's western flank in the mid-to-upper slope. ...

[show less] The latest report by the volcano observatory in Catania indicates that on that day, 20 earthquakes were detected with magnitudes of 1.0 or greater in total, including 4 quakes greater than magnitude 2.0 and one of magnitude 3.3 at 04:20 UTC approximately 600 meters southwest of Monte Minardo at a depth of 6.3 kilometers. On 19 and 20 Oct, the volcano was quieter, with only two small events detected: a magnitude 1.2 earthquake near Monte Fontane and a magnitude 1.8 event near Maletto.Most monitored parameters at Etna, such as ground deformation, degassing rates, overall thermal radiation (as observed via satellite data), and infrasonic events (indicating degassing events or explosions deep inside the conduits), have not shown significant variations in the past few weeks, meaning that there is currently no indication that a new eruption is imminent.Sakurajima (Kyushu, Japan): The Volcanic Ash Advisory Center (VAAC) Tokyo issued the following bulletin.Original VAAC bulletin: EXPLODED AT 20261021/1220Z OVER FL050 EXTD SE OBS VA DTG: 21/1210ZTaal (Luzon, Philippines): An eruption was reported at Taal, with the latest observation at 21 October 2026, 15:40 UTC. No volcanic ash cloud was identifiable in satellite data at that time.Original VAAC bulletin: eruption reported as of 21 Oct 2026, 15:40 UTCIbu (Halmahera, Indonesia): (20 Oct) Explosive activity continues. The Volcanic Ash Advisory Center (VAAC) Darwin warned of a volcanic ash plume rising to an estimated 6000 ft (1800 m), or flight level 060.Original VAAC bulletin: ash plume to 6,000 ft (1,800 m) as of Oct 20, 20:20 UTCLewotolo (Lesser Sunda Islands): Strombolian activity persists at the volcano and the lava flow from the summit vent remains active as well, as recent webcam imagery shows.Krakatau (Sunda Strait, Indonesia): (21 Oct) Explosive activity continues. The Volcanic Ash Advisory Center (VAAC) Darwin warned of a volcanic ash plume rising to an estimated 8000 ft (2400 m), or flight level 080.Original VAAC bulletin: ash plume to 8,000 ft (2,400 m) as of Oct 21, 05:00 UTCDukono (Halmahera): (20 Oct) Explosive activity continues. The Volcanic Ash Advisory Center (VAAC) Darwin warned of a volcanic ash plume rising to an estimated 7000 ft (2100 m), or flight level 070.Original VAAC bulletin: ash plume to 7,000 ft (2,100 m) as of Oct 20, 22:00 UTCWhite Island (New Zealand): Explosive activity continues. The Volcanic Ash Advisory Center (VAAC) Wellington warned of a volcanic ash plume rising to an estimated 5000 ft (1500 m), or flight level 050, and moving at 05 kts in S direction.Original VAAC bulletin: ash plume to 5,000 ft (1,500 m) as of Oct 21, 10:28 UTC...21 Oct:During an observation flight on 20 October 2026, the activity at Whakaari/White Island was confirmed to have transitioned from intermittent to continuous passive emission of steam, gas, and minor amounts of volcanic ash. Ash accumulation was observed around the active vent in the Main Crater and across parts of the crater floor and outer flanks. The discharge remained weak, with no evidence of explosive activity. However, the vent temperature had increased significantly from approximately 100°C to 395°C over the preceding week, while satellite observations detected daily SO₂ emissions.In response to the continuous ash emission, increased vent temperature, and potential increase in gas output, the Volcanic Alert Level was raised to Level 3 and the Aviation Colour Code to Orange. Minor ashfall was considered likely on and near the island, although no ash impacts had been reported on the mainland. The current activity was assessed as consistent with previous eruptive cycles at Whakaari, potentially continuing for several weeks. ... [read more] ... [show less] Despite the currently low-energy nature of the eruption, the possibility of rapid escalation with little or no warning remains. More explosive activity could generate ballistic projectiles, ash emissions, and pyroclastic surges, posing a threat to life in the Main Crater and offshore areas southeast of the island. Ashfall could also affect aircraft and vessels near the volcano, while significant impacts on the mainland remain very unlikely under the current conditions.Fuego (Guatemala): Explosive activity continues. The Volcanic Ash Advisory Center (VAAC) Washington warned of a volcanic ash plume rising to an estimated 14000 ft (4300 m), or flight level 140.Original VAAC bulletin: ash plume to 14,000 ft (4,300 m) as of Oct 21, 12:40 UTCSangay (Ecuador): Explosive activity continues.
