Mayon Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. Moderate emission of white steam plumes that drifted towards southwest and northwest was observed. The summit was visible but no crater glow was observed last night. Precise leveling survey results from August 25-30, 2015 indicated very slight deflation of the edifice relative to July 2015, consistent with short-term deflation recorded by continuous GPS since August 2015 and electronic tilt since March 2015.

Alert Level 1 remains in effect over Mayon Volcano, which means that it is at abnormal condition. Although this means that presently no magmatic eruption is imminent, it is strongly advised that the public refrain from entering the 6-kilometer radius Permanent Danger Zone (PDZ) due to the perennial life-threatening dangers of rockfalls, landslides/avalanches at the middle to upper slope, sudden ash puffs and steam-driven or phreatic eruptions from the summit. Active stream/river channels and those identified as perennially lahar-prone areas on all sectors of the volcano should also be avoided especially during extreme weather conditions when there is heavy and prolonged rainfall. DOST-PHIVOLCS maintains its close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders.
