In the past 24-hour period, the Mayon Volcano Network did not detect any volcanic earthquakes. A faint crater glow from the summit could be observed at night. Sulfur dioxide (SO2) emission was last measured at an average of 201 tonnes/day on 02 March 2023. Ground deformation parameters from electronic distance measurement, precise leveling, electronic tilt, and continuous GPS monitoring indicate inflation since 2020, while shorter-term parameters indicate a more pronounced inflation since the second week of February 2023.
Alert Level 2 (Increased Unrest) prevails over Mayon Volcano. The public is reminded that there is current unrest driven by shallow magmatic processes that could eventually lead to phreatic eruptions or even precede hazardous magmatic eruptions. Entry into the six (6) kilometer-radius Permanent Danger Zone (PDZ) must be strictly prohibited to minimize risks from sudden explosions, rockfalls, and landslides. In case of ash fall events that may affect communities downwind of Mayon’s crater, people should cover their nose and mouth with a damp, clean cloth, or dust mask. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ash from any sudden eruption can be hazardous to aircraft. DOST-PHIVOLCS maintains close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders.
