Stromboli (Eolian Islands, Italy): Activity at the volcano remains comparably elevated. When observed last night, the most active vents were the two ones in the northern crater area. The western vent in that area (the one to the right when seen from the observation areas) showed continuous mild spattering, interrupted by frequent, but mostly small strombolian type explosions which often generated small incandescent rock falls on the Sciara del Fuoco. … [read more] … [show less] The easternmost vent was characterized by constant glow, occasional weak spattering, and strong bubble-bursting explosions at intervals of approx. 20 minutes. Incandescent lava bombs were ejected radially from the vent to heights estimated 2-300 m. Most explosions were accompanied by detonating sounds; shock waves from this activity are regularly perceived throughout the village of Stromboli as well, generating short rattling of doors and windows.
Etna (Sicily, Italy): An eruption was reported at Etna on 29 Oct 2026 at 06:00 UTC, but no ash cloud has been observed as of 30 Oct 2026, 15:30 UTC. No volcanic ash is expected in the next 18 hours. Original VAAC bulletin:no ash cloud observed as of 30 Oct 2026, 15:30 UTC

Mayon (Luzon Island, Philippines): A moderate explosion took place from the volcano’s summit crater today. At about 11:53 AM local time, a towering pillar of gas, ash and other ejecta rose to about 3 km above the crater, drifting west-southwest. … [read more] … [show less] Around 120 families have been evacuated from nearby areas, including Camalig and Tabaco City. In addition, air traffic was also disrupted due to strong ash emissions in the atmosphere.
Langila (New Britain, Papua New Guinea): 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 30, 10:40 UTC
Karangetang (Siau Island, Sangihe Islands, Indonesia): (30 Oct) The activity at the volcano continues at elevated levels. Eruptions have been intensifying over the past week, mainly from the northern crater. … [read more] … [show less] In addition, the local webcam likely detected a new lava flow from the northern crater emerging westward. If not, it might be an occurrence of glowing rockfalls from the vent.
