MAYON VOLCANO BULLETIN 14 July 2014 8:00 A.M. PDF Print

Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network did not detect any volcanic earthquake during the past 24-hour observation period. ·Moderate emission of white steam plumes that crept downslope towards west-southwest and west-northwest was observed. No crater glow was observed last night. Sulfur dioxide (SO2) flux was measured at an average of 397 tonnes/day on 10 July 2014. Ground deformation measurements from precise leveling surveys on the 2nd week of June 2014 showed inflationary changes in the edifice from February 2014. Tilt data shows that the edifice is still inflated compared to January 2012 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.
