• Mayon erupts as Alert Level rises to 3 and ash spreads south, Philippines

    An explosive eruption occurred at Mayon Volcano in Albay, Philippines, at 11:53 LT on October 30, 2026, sending a dense ash plume 3 000 m (9 843 feet) above the summit crater and prompting DOST-PHIVOLCS to raise the volcano from Alert Level 2 to Alert Level 3. By 19:20 LT, Tokyo VAAC was still detecting volcanic ash in Himawari-9 satellite imagery moving south, with ash analyzed up to FL180 and forecast up to FL190 during the following six hours.

  • Explosive strombolian eruptions at Mayon volcano, Philippines

    Mayon volcano remained under Alert Level 3 on July 15, 2026, after PHIVOLCS recorded 187 volcanic earthquakes, 398 rockfalls, 10 pyroclastic density current signals, and SO2 emissions averaging 9 028 tonnes/day from the volcano in Albay, Philippines.

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

    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.

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

    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.

  • Pyroclastic density currents from Mayon volcano reach 4 km (2.5 miles), Philippines

    A series of collapse-fed pyroclastic density currents descended the Mi-isi Gully at Mayon volcano, Philippines, on February 9, 2026, with the farthest runout reaching 4 km (2.5 miles) from the summit crater. The activity peaked between 10:35–11:37 local time (LT), culminating in a seven-minute event at 10:59 LT that generated ash clouds exceeding 2 km (about 6 560 feet) in height and causing ashfall across parts of Camalig and Guinobatan, Albay, during rainy conditions.

  • Evacuations underway after Mayon volcano’s dome collapse and pyroclastic flows, Philippines

    Nearly 3 000 residents have been evacuated from communities around Mayon volcano in Albay Province, Philippines, after the Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the alert status to Level 3 on January 6, 2026. The evacuation follows intensified dome collapse events, pyroclastic density currents, and ongoing effusive lava extrusion at the summit.
