Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network did not detect any volcanic earthquake during the past 24-hour observation period. ·Steaming activity and crater glow could not be observed due to thick rain clouds that covered the summit. Sulfur dioxide (SO2) emission was measured above baseline at an average of 1,373 tonnes/day on 21 January 2014, an increase from the previous measurement of 915 tonnes/day on 24 December 2013. ·Ground deformation survey (precise leveling) on the 2nd week of November 2013 showed slight deflation of the edifice compared to August 2013 survey, with the volcano still slightly inflated compared to January 2010 baselines.·

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.
