Roundup of Global Volcanic Activity

Sakurajima (Kyushu, Japan): Activity remains low. Only small-scale explosions occurred during the past weeks from the Showa crater. The Alert Level remains at 3 (out of 5).

Rinjani (Lombok): The eruption of the volcano continues to produce intense ash emissions. However, to the great relief of travellers to and from Bali, the strong easterly winds that had swept the plume over Bali during the past days, forcing the Denpasar International airport to shut down, have ceased and given way to weak southerly and northerly winds, thus allowing the airport to reopen. Some Australian airlines have been adding extra flights to Bali to help the many stranded travellers return home. On this morning's satellite image, the ash plume can be seen hovering in N-S direction across Lombok island, while Bali was free of ash. However, easterly winds are likely to pick up again soon, which could cause significant flight disruptions again.

Kilauea (Hawai'i): No significant changes have occurred at the volcano recently. HVO reported that seismicity beneath Kilauea's summit, upper East Rift Zone, and Southwest Rift Zone was at background levels during 28 October-3 November. The lava lake continued to circulate and spatter in the Overlook vent. The June 27th NE-trending lava flow continued to be active within 2.2-6.3 km NE of Pu'u 'O'o Crater.

Shishaldin (Aleutian Islands, Alaska): Seismicity at Shishaldin continued to be slightly elevated over background levels during 28 October-2 November, indicating that low-level eruptive activity confined to the summit crater continued. The Aviation Colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Santiaguito (Guatemala): Heavy rainfalls caused several lahars during the past days. The volcano continues to produce occasional small to moderate explosions from the active Caliente dome.

Pacaya (Guatemala): Weak, deep-seated explosive activity continues inside the Mackenney crater. INSIVUMEH reports moderate degassing creating a plume of 150-200 m height with pulsating emissions of bluish gas. At night, weak glow is visible from the crater.

Fuego (Guatemala): The volcano has been at average activity levels during the past days, with intermittent weak to moderate, sometimes stronger strombolian-type explosions (every 1-3 hours on average), sometimes accompanied by shock waves. Ash plumes rose 500-800 m above the crater, incandescent rockfalls occurred during the stronger eruptions and light ash fall was noted in nearby areas.

Ubinas (Peru): A small explosive eruption occurred last evening, producing an ash plume that rose approx. 1 km above the crater and quickly dissipated. Seismic activity at the volcano remains low, according to the corresponding bulletin of Buenos Aires VAAC. ...6 Nov: Activity at the volcano remains low, with weak emissions of gas and steam, sometimes mixed with ash. Seismic activity fluctuated at low levels during the past week.

Heard (Australia, Southern Indian Ocean): A plume from Heard was visible in a satellite image drifting SSW on 30 October. This suggests some sort of activity still going on from the remote volcano in the Kerguelen Islands.
