• PVMBG raises Lewotobi Laki-laki to Level III after seismicity and inflation increase, Indonesia

    ByTeo Blašković

    Indonesia’s Center for Volcanology and Geological Hazard Mitigation (PVMBG) raised the alert level for Lewotobi Laki-laki in East Flores, East Nusa Tenggara, from Level II to Level III at 13:00 WITA (05:00 UTC) on May 12, 2026. The decision followed increased deep volcanic earthquakes, persistent non-harmonic tremor, inflation, and surface activity from May 1 to 11. Residents and tourists were told to avoid activity within a 5 km (3.1 miles) radius of the eruption center.

    Indonesia’s North Halmahera government permanently closed climbing access to Mount Dukono after 3 climbers were found dead following the May 8, 2026, eruption on Halmahera Island, North Maluku. BNPB said the area had already been under a total climbing closure since April 17, before the closure was reinforced through a May 8 Regent decision barring operators, managers, and climbing-service providers from issuing permits.

  • Increased seismicity and gas emissions at Kupreanof volcano, Alaska

    ByTeo Blašković

    Seismic activity and sulfur dioxide emissions have increased at Kupreanof volcano in Alaska over recent months, likely due to magmatic intrusion beneath the volcano. Kupreanof is a heavily glaciated stratovolcano on the Alaska Peninsula with no known historical eruptions. Current data do not indicate an eruption is imminent.

  • Repeated lava-collapse pyroclastic flows continue at Mayon volcano, Philippines

    ByTeo Blašković

    Mayon volcano remained under Alert Level 3 on Friday, May 8, 2026, with PHIVOLCS reporting lava flows in three gullies, elevated sulfur dioxide emissions, volcanic earthquakes, and repeated lava-collapse pyroclastic flow activity. Today’s observations follow a large eruption sequence on May 2, when collapse-generated pyroclastic flows traveled up to 5 km (3.1 miles), generating widespread ashfall across parts of Albay Province and prompting evacuations affecting thousands of residents.

  • Kīlauea episode 46 ends after 9 hours of lava fountaining, tephra reaches Highway 11, Hawaii

    Episode 46 of the ongoing Halemaʻumaʻu eruption at Kīlauea ended at 17:22 HST on May 5, 2026 (03:22 UTC on May 6), after about 9 hours of continuous lava fountaining from the north vent at the summit. USGS lowered the Volcano Alert Level from Watch to Advisory and the Aviation Color Code from Orange to Yellow after ground and aviation hazards decreased.

  • Lava flow from Stromboli’s North crater reaches coastline, Italy

    ByTeo Blašković

    Lava overflow activity increased at Stromboli from 21:20 LT (19:20 UTC) on May 4, 2026, sending a flow from the North crater area down the Sciara del Fuoco to the coastline by about 03:00 LT (01:00 UTC) on May 5. INGV reported average volcanic tremor, a slight increase in explosion-related earthquakes, and no significant GNSS change.

  • Intense spattering feeds lava overflow at Stromboli, Italy

    ByTeo Blašković

    Stromboli’s North Crater area is producing intense spattering on May 4, 2026, feeding a lava overflow onto the Sciara del Fuoco, INGV-OE reported at 11:21 UTC. The lava front was in the middle-upper section of the slope, while volcanic tremor was in the high range.

  • Strong eruption at Mayon volcano generates large pyroclastic flows, heavy ashfall in Albay, Philippines

    ByTeo Blašković

    Pyroclastic density currents generated by a lava collapse at Mayon volcano in Albay, Philippines, on May 2, 2026, reached an estimated runout distance of 4 km (2.5 miles) along Mi-isi Gully and produced ashfall affecting 52 barangays across Guinobatan, Camalig, and Ligao City. Ashfall reduced visibility to near zero in parts of Camalig, blanketed homes, roads, crops, and grazing land, and prompted face mask distribution and health advisories.
