MAYON VOLCANO BULLETIN: 02 July 2020 08:00 A.M.
Mayon Volcanos seismic monitoring network recorded one 1 volcanic earthquake during the 24hour observation period. Moderate emission of white steamladen plumes that drifted to the general west was observed. Faint crater glow from the summit could be observed at night. Sulfur dioxide SO2 emission was last measured at an average of 229 tonnesday on 30 June 2020. Ground deformation data from Precise Leveling surveys on 1219 June 2020 indicate a slight inflation of the edifice relative to February 2020 survey. Electronic tilt data also indicated nonsteady inflation of the middle to upper edifice that began in late 2019. This follows an inflationary trend that has been recorded by continuous GPS monitoring since the middle of 2019.DOSTPHIVOLCS reiterates that Alert Level 2 currently prevails over Mayon because the volcano is at a moderate level of unrest. It is therefore strongly recommended that entry into the six kilometerradius Permanent Danger Zone or PDZ and a precautionary seven kilometerradius Extended Danger Zone or EDZ in the southsouthwest to eastnortheast sector, stretching from Anoling, Camalig to Sta. Misericordia, Sto. Domingo should be strictly prohibited. The public is reminded that sudden explosions, lava collapse, pyroclastic density currents or PDCs and ashfall can occur without warning and threaten areas in the upper to middle slopes of Mayon. People residing close to these danger areas are also advised to observe precautions against rockfalls, PDCs, and ashfall. Active streamriver channels and those identified as perennially laharprone areas on all sectors of the volcano should also be avoided especially during extreme weather conditions when there is heavy and prolonged rainfall. Civil aviation authorities must advise pilots to avoid flying close to the volcanos summit as airborne ash and ballistic fragments from sudden explosions and PDCs may pose hazards to aircraft.DOSTPHIVOLCS is closely monitoring Mayon Volcanos condition and any new development will be relayed to all concerned.DOSTPHIVOLCS
