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.
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.
More than 300 families were evacuated in Albay province, Philippines, after ashfall from Mayon volcano affected 87 villages across three towns over the weekend following a lava collapse on May 2, 2026. Officials reported no deaths or injuries, but ash reduced road visibility, damaged vegetable farms, and killed livestock in Camalig.
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.
More than 25 million m³ (883 million ft³) of magma has accumulated beneath Svartsengi, Iceland, since the last eruption in July 2025, the Icelandic Meteorological Office (IMO) reported on April 28, 2026. IMO said ground uplift continues at up to 2 cm (0.8 inches) per month, while magmatic dike propagation toward the Sundhnúkur crater row remains the most likely scenario and could lead to an eruption.
Lava fountains rising to 300 m (1 000 feet) and an ash plume reaching 5 000 m (16 500 feet) marked the onset of episode 45 at Kīlauea on April 23, 2026, triggering an ashfall advisory for Kaʻū. Activity remained confined within Halemaʻumaʻu as fountain heights stabilized after an early peak.
Authorities raised the volcanic alert level to V1 in the Faial–Pico channel, Azores, Portugal, on April 9, 2026, following low-magnitude seismic activity that began on April 1. The earthquakes occurred along a NE–SW trend west of Madalena to north of Lagido, spanning depths from 20 km (12 miles) to near the surface. The last known eruption at this volcano took place in 1720, with a Volcanic Explosivity Index (VEI) of 2.
Mount Dempo in South Sumatra, Indonesia, erupted at 04:45 UTC on April 15, 2026, sending volcanic ash as high as 7.6 km (25 000 feet) above sea level and prompting Indonesia’s volcano agency to raise the Aviation Color Code to Red. The eruption follows a phreatic blast on April 7 and inflation detected from April 2.
Tephra up to 25 cm (10 inches) was reported in the Volcano Golf Course subdivision near Kīlauea, Hawaiʻi, during episode 44 of the ongoing summit eruption, which ended at 05:41 UTC on April 10, 2026, after 8 hours and 31 minutes of lava fountaining. The eruption generated 5.8 million m³ (7.5 million cubic yards) of lava, while ash and Pele’s hair reached as far as Hilo, prompting warnings and temporary closures.
Explosive activity at Sheveluch volcano, Kamchatka, Russia, sent volcanic ash to 11 km (36 000 feet) above sea level on March 29, 2026, prompting authorities to raise the Aviation Color Code to Red.
