The facts

  1. PHIVOLCS recorded a moderately explosive eruption at 11:53 a.m. Philippine time on 30 October (03:53 UTC). Its 12:30 p.m. bulletin raised the alert to Level 3. [1]

  2. The ash plume travelled west-southwest. The agency expected ashfall in Daraga, Guinobatan, Camalig and neighbouring Albay communities. [1][2]

  3. Scientists recommended evacuating the six-kilometre Permanent Danger Zone because of potential lava, rockfalls and fast-moving hot volcanic material. They also warned of mudflows and sediment-laden water in drainage channels. [1][3]

  4. GMA reported that the aviation authority issued a notice covering airspace near Mayon from the surface to 19,000 feet, from 1:27 p.m. on 30 October until 11:53 a.m. on 31 October, Philippine time. This cited notice's end time has passed; it is not evidence of a current open-ended airspace restriction. [4]

  5. APSEMO's monitoring report for October 30 at 5 p.m. Philippine time recorded 746 families, comprising 2,041 people, evacuated from Tabaco, Camalig and Ligao. The figures were reported on October 31 by GMA and Philstar. [5][7]

  6. Reports describe ash emission at 5:17 a.m. Philippine time on October 31 while Alert Level 3 remained. GMA also reports ready-to-eat food assistance to 123 families in Anoling, Camalig; that is not a count of assistance distributed to every evacuee. [6][7]

Relevant context

The alert describes a new magmatic phase and heightened hazards over the coming days to weeks. It does not establish that an explosive eruption is continuing without interruption. [1][3]

Still unconfirmed

  • The later evacuation total and complete damage or casualty assessment remain unresolved in the checked reports.

Corrections & updates

Substantive update: Added the provincial monitoring count of 2,041 evacuees from 746 families as of 5 p.m. Philippine time on October 30, corroborated by October 31 reporting, plus the continuing alert and ash emission. This replaces the absence of a verified evacuation count without treating it as a live total. The earlier aviation notice retains its actual, now-expired time window.
