Mayon Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. Weak to moderate emission of white steam plumes that drifted west-southwest was observed. Precise leveling data obtained on September 16-21, 2017 indicated slight inflation of the edifice relative to May 2017 survey. Continuous GPS and tiltmeter measurements also indicate inflationary trend since July 2016. Sulfur dioxide (SO2) emission was measured at an average of 259 tonnes/day on October 04, 2017.

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.
