Mayon Volcano had one volcanic quake, still under Alert Level 2 —PHIVOLCS

The Mayon Volcano in Albay had one volcanic earthquake and two rockfall events in the past 24 hours, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS) on Monday. 

PHIVOLCS revised its earlier bulletin which previously showed 21 volcanic earthquakes.

Alert Level 2 (Increased Unrest) is still in effect in Mayon Volcano.

PHIVOLCS said a faint crater glow visible via telescope has been observed.

A total of 294 tonnes of sulfur dioxide were emitted by the volcano on Saturday, February 18.

Moderate plumes rose up to 200 meters tall and these drifted generally westward.

The volcano edifice remains inflated.

PHIVOLCS reiterated that entry into the six-kilometer radius Permanent Danger Zone of the volcano is not allowed.

Likewise, flying any aircraft close to Mayon Volcano is prohibited.

PHIVOLCS warned that sudden steam-driven or phreatic eruptions, rockfalls or landslides or avalanches, and lahars during heavy and prolonged rainfall may possibly occur. —KG, GMA Integrated News
