Twin Unrest at Mayon and Kanlaon Prompts Expanded Lock-downs in Philippine Volcano Danger Zones
On 5 May 2026, Mayon’s lava-collapse sent a pyroclastic current while Kanlaon lofted twin 800 m ash plumes, forcing police to seal a 6-km (possibly 7-km) cordon at Mayon and keeping Kanlaon at Alert Level 2.
Focusing Facts
- Kanlaon emitted ash at 5:32 a.m. and 6:01 a.m., generating 800 m gray plumes; Phivolcs tallied 5 ash events, 22 quakes, and 2,975 t/day SO₂ within 24 hrs.
- Mayon produced a pyroclastic density current from 7:19–7:26 a.m.; Alert Level 3 remains, with PNP deploying round-the-clock checkpoints to enforce a 6-km PDZ and considering a 7-km expansion.
- Ground deformation at both cones remains inflated, indicating continuing magma pressurization.
