Awareness and Preparedness
|MAYON VOLCANO BULLETIN 19 June 2012 8:00 A.M.|
Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network did not record any volcanic earthquake during the past 24-hour observation period. Steaming activity and crater glow could not be observed due to thick clouds covering the summit. Sulfur dioxide (SO2) emission rate on 15 June 2012 was measured at an average of 356 tonnes per day. Ground deformation survey (precise levelling) last 01-04 May 2012 showed no significant change compared to February 2012.
Mayon Volcano’s alert status remains at Alert Level 1. Although this means that no eruption is imminent, it is strongly advised 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 condition 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.
