Mayon Volcano emitted an ash plume that rose 200 meters above its summit crater on Saturday morning, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported.
The ash emission was recorded at 5:17 a.m. through the volcano’s IP cameras at the Mayon Volcano Ligao Monitoring Station and the Mayon Volcano Observatory in Ligñon Hill.
According to PHIVOLCS, the plume drifted west-southwest after rising above the summit crater.
“Alert Level 3 prevails over Mayon and entry into the 6-km Permanent Danger Zone should be prohibited,” PHIVOLCS said.
In its 24-hour monitoring bulletin, PHIVOLCS reported one moderately explosive eruption lasting six minutes, along with 15 volcanic earthquakes and 30 rockfall events.
The volcano also recorded a sulfur dioxide (SO2) emission rate of 988 metric tons per day on October 30.
Steaming activity was observed at heights ranging from 100 to 3,000 meters above the crater, with moderate to very strong emissions drifting toward the west-northwest and west-southwest.
Ground deformation measurements also indicated swelling of the volcano, accompanied by short-term deflation in its northeastern sector.
The agency reiterated that entry into the six-kilometer Permanent Danger Zone (PDZ) must be strictly prohibited due to the ongoing threat posed by the volcano.
Residents and local authorities were advised to remain vigilant and follow official advisories as monitoring of Mayon's activity continues.
