Mayon Volcano’s (13.2576°N, 123.6856°E) seismic network detected two (2) rock fall-related events during the past 24 hours. Steaming activity from the crater varied from weak to moderate with white steam clouds creeping downslope towards west-northwest. Fair crater glow (Intensity II- can be seen by naked eye) was observed last night. Result of ground deformation survey (precise leveling) conducted last 06-10 March 2011 showed slight deflation of volcano edifice as compared with 05-10 January 2010 baseline survey.

Alert Level 1 is 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.
