Phivolcs Lifts Alert Level at Mayon Volcano Following Decreased Unrest

Phivolcs Lifts Alert Level at Mayon Volcano

The state volcanology bureau Phivolcs lifted the alert level at Mayon Volcano following the decreased signs of unrest.

On Friday (July 30, 2021), the Philippine Institute of Volcanology and Seismology (Phivolcs) has finally lifted the alert status of Mayon Volcano following the continuous decrease in all monitoring parameters.

Last July 17, 2020, Phivolcs lowered the alert status of Mayon from Alert Level 2 to Alert Level 1 due to the continues declination of irregularities at the volcano. No magmatic eruption is expected.


“Phivolcs is now lowering the alert status of Mayon from Alert Level 1 to Alert Level 0. This means observational parameters have returned to baseline levels and no magmatic eruption is foreseen in the immediate future,” the agency said.

The seismology agency also reported that Mayon Volcano declined to baseline levels with zero to five events per day. The sulfur dioxide emission from Mayon’s crater also declined, which is a good sign.

However, Phivolcs also advised the public to avoid entry into the 6-kilometer Permanent Danger Zone due to hazards of rockfalls, avalanches, ash puffs, and sudden steam-driven or phreatic eruption.


The agency will continue to monitor the volcano and would continue to release update regarding new development.
