Overview
- A moderately explosive eruption on Friday, Oct. 30, lasted about six minutes and sent a gray ash column roughly 3,000 metres above Mayon’s summit, according to Phivolcs.
- Phivolcs raised Alert Level 3 and recommended evacuation of communities inside the 6-kilometre Permanent Danger Zone because of the heightened risk of lava flows, pyroclastic density currents, rockfalls and other near-vent hazards.
- The ash plume initially drifted west-south-west with prevailing winds likely to bring ash to the south side of Mayon and possible ashfall in Daraga, Guinobatan and nearby Albay towns.
- Authorities warned residents to watch for lahars and sediment-laden streamflow in channels draining the volcano and said they will maintain close monitoring and update stakeholders, while aviation regulators had not issued a Notice to Airmen at the time of the reports.
- Mayon is one of the Philippines’ most active volcanoes and the raised alert means officials expect an elevated hazard window over days to weeks that could disrupt local life, farming and travel if further magmatic activity continues.
