At least one volcanic earthquake and 59 rockfall events were observed in Mayon Volcano, Albay in the last 24 hours, the state seismologists reported on Saturday, June 10.

In its 8 AM bulletin, the Philippine Institute of Volcanology and Seismology (Phivolcs) said that the rockfall activities placed lava debris on gullies within 1,500 meters from the volcano’s summit crater.

Mount Mayon emitted 417 tonnes of Sulfur dioxide since Friday, June 9, and it produced steam-laden plumes that are drifting southeast.

“Longer-term ground deformation parameters based on EDM, precise leveling, continuous GPS, and electronic tilt monitoring indicate that Mayon is still inflated, especially on the northwest and southeast,” Phivolcs said.

On Friday evening, the state seismologist posted a photo showing the fair crater glow or banaag that occurred around Mayon Volcano’s summit lava dome.

The Mayon Volcano is still under Alert Level 3 since Thursday, June 8 as it exhibited a high level of unrest with a hazardous eruption possible within the next weeks or days.

The state seismologist recommended the immediate evacuation of individuals situated inside the 6-kilometer radius Permanent Danger Zone (PDZ) as they are at risk of Pyroclastic density currents (PDCs), lava flows, rockfalls, and other volcanic hazards.

According to Phivolcs, ash fall events may occur in Mayon’s south side.

The state seismologist earlier said that it is considering the possibility of raising the Alert Level of Mayon Volcano from 3 to 4.

The province of Albay is now under a state of calamity in response to the unrest of the Mayon volcano.
