Mayon Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. Weak emission of white steam plumes that drifted west-southwest was observed. No crater glow was observed last night. Precise leveling surveys on April 30 to May 4, 2015 indicated slight deflation of the edifice relative to the March 2015 surveys, although the edifice remains inflated relative to baseline levels.  

Mayon Volcano’s alert status is currently at Alert Level 2. This means the volcano is at a moderate level of magmatic unrest. Although the volcano is currently exhibiting low-level of seismic activity, ground deformation data indicates that eruptible magma had already accumulated the previous year beneath the edifice. Current conditions may still change and eventually lead to hazardous eruption. The public is still reminded to avoid entry into the 6-km Permanent Danger Zone or PDZ due to perennial hazards of rockfalls, avalanche, ash puffs and sudden steam-driven or phreatic eruptions at the summit area. Furthermore, people living in valleys and active river channels are cautioned to remain vigilant against sediment-laden streamflows and lahars in the event of prolonged and heavy rainfall. PHIVOLCS-DOST is closely monitoring Mayon Volcano’s activity and any new development will be immediately posted to all concerned.
