Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network recorded three (3) volcanic earthquakes during the past 24-hour observation period. Moderate emission of white steam plumes that drifted west-southwest was observed. No crater glow was observed last night. Sulfur dioxide (SO2) emission was measured at an average of 187 tonnes/day on 28 January 2014. Geodetic results from ground deformation survey (precise leveling) on the 2nd week of November 2013 and tiltmeter values showed that the edifice of the volcano is still inflated compared to January 2010 and January 2012 baselines, respectively.
Mayon Volcano’s alert status remains at Alert Level 1, 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.
