No volcanic earthquake was detected by the Mayon Volcano’s (13.2576°N, 123.6856°E) seismic network during the past 24 hours. Moderate emission of white steam was observed during cloud breaks. Crater glow remained at Intensity II as observed last night. Result of ground deformation surveys conducted last November and December 2010 showed that the volcanic edifice remains inflated based on 2008 baseline data.
Alert Level 1 is in effect over Mayon Volcano. While this means 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 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 and any new development will be relayed to all concerned.
