Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network did not record any volcanic earthquake during the past 24 hour. Steaming activity was at moderate level as white steam clouds drifted to the southwest. Crater glow was observed at Intensity II (visible to naked eye) last night. Results of ground deformation survey (precise leveling) conducted last 31 May 2011 to 04 June 2011 showed slight inflation of the volcano’s edifice as compared with 06-10 March survey.
Alert Level 1 remains in effect over Mayon Volcano. Although this means that no eruption is imminent, it is recommended that the public should not enter the 6-kilometer radius Permanent Danger Zone (PDZ) due to the continuing threat from sudden small explosions and rockfalls from the upper and middle slopes of the volcano. Active stream/river channels and those perennially identified as lahar prone areas in the southern sector should also be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall. DOST-PHIVOLCS is closely monitoring Mayon Volcano’s activity and any new development will be relayed to all concerned.
