The seismic network at Mayon Volcano (13.2576°N, 123.6856°E) recorded one (1) rockfall event during the past 24 hours. Steam emission was white and moderate while crater glow was not observed due to thick clouds covering the summit. Results 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.
