Mayon Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. Moderate emission of white steam plumes that crept downslope towards southwest was observed. The summit was visible but no crater  glow was observed last night. Precise leveling survey results on November 21-28, 2015 indicated a slight inflation of the edifice relative to August 2015 consistent with the continuous GPS data since October 2015, although short-term deflation was recorded by 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.
