Mayon Volcano in Albay showed minor Strombolian activity on Wednesday, generating a plume that rose 500 meters above its summit crater, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said.

In a Facebook post, PHIVOLCS said camera footage captured the activity at around 11:56 a.m. through the Mayon Volcano Observatory Ligñon Hill (VMLH) IP camera.

“This event generated a plume that rose 500 meters above the summit crater as captured by the Mayon Volcano Observatory Ligñon Hill (VMLH) IP camera,” PHIVOLCS said.

Alert Level 3, or intensified unrest due to magmatic activity, remains in effect over Mayon, according to PHIVOLCS.

Four volcanic earthquakes and five rockfall events were recorded over Mayon Volcano, based on PHIVOLCS’ latest bulletin.

The volcano emitted 2,170 tonnes of sulfur dioxide per day on November 10.

Moderate emission of volcanic plume was also observed, with the plume drifting toward the southwest.

Ground deformation data showed inflation of the volcanic edifice and short-term deflation in its northeastern sector.

PHIVOLCS reiterated that entry into Mayon's six-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited.

Aircraft are also prohibited from flying close to the volcano.

Possible hazards include rockfalls, landslides, avalanches, ballistic fragments, lava flows and lava fountaining, pyroclastic density currents, and moderate-sized explosions.

Lahars may also occur during heavy and prolonged rainfall. —VAL, GMA News
