Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network did not detect any volcanic earthquake during the past 24 hours. Visual observation was not possible due to rain clouds prevailing over the volcano area.  Ground deformation survey (precise leveling) last 31 May to 04 June 2011 showed a slight inflation of the edifice as compared with 06-10 March 2011.

 

Alert Level 1 remains in effect over Mayon Volcano.  Although this means that no eruption is imminent, it is recommended that the public refrain from entering the 6-kilometer radius Permanent Danger Zone (PDZ) due to the threat of sudden steam-driven eruptions and rockfalls from the upper and middle slopes of the volcano. Active stream/river channels and those identified as perenially lahar prone areas on all sectors of the volcano 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.
