Mayon Volcano’s (13.2576°N, 123.6856°E) seismic network recorded two (2) volcanic earthquakes for the past 24 hours. White steam emission from the crater ranged from weak to moderate during the same observation period.  Fair crater glow (Intensity II – seen with naked eye) was observed last night. 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 1is 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.
