This serves as a notice for the raising of Mayon Volcano's status from Alert Level 1 (abnormal) to Alert Level 2 (increasing unrest).
Mountain Mayon, one of the most active Philippine volcanos, famous for its beauty and near-perfect symmetry, is in Albay province on the Philippine main Luzon Island, more than 300 km southeast of the Philippines capital Manila.
Yesterdayy afternoon, Phivolcs recorded a phreatic eruption that lasted for an hour and 47 minutes prompting provincial authorities to conduct an evacuation of several barangays near Mayon.
PHIVOLCS said traces of ash fell on Barangay Anoling in Daraga, Barangays Sua, Quirangay, Tumpa, Ilawod, Salugan of Camalig, and Barangays Tandarora, Maninila, and Travesia in Guinobatan.
"Sulphurous door was detected and rumbling sounds were heard by residents of Brgy". Faint crater glow has been first observed at 10:16 PM.
"The second phreatic eruption produced a greyish steam and ash plume that was largely obscured by summit clouds", the institute said, adding that a strong smell of sulfur pervaded affected areas. This indicates pressurization of the edifice by rising magma or its perturbation of Mayon's subsurface hydrothermal system.

He went on: "We have not reached the critical level".
"This means that current unrest is probably of magmatic origin, which could lead to more phreatic eruptions or eventually hazardous magmatic eruptions", PHIVOLCS said in a 12:30 a.m. bulletin, Sunday.
PHIVOLCS further said the public should refrain from entering the 6-kilometer radius of the Permanent Danger Zone (PDZ) to minimize risks from sudden explosions, rockfall, and landslides.
The bulletin advised residents to prepare for "ash fall events" as pilots were urged to avoid flying close to the summit of the volcano.
Also ash-fall events may affect the communities on the western and southwestern sides of Mayon Volcano. DOST-PHIVOLCS maintains close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders.
