Alert Level 1 remains in effect at Negros Island’s Kanlaon volcano, as Mayon volcano in Albay province undergoes a localized magmatic eruption, as reported by the Philippine Institute of Volcanology and Seismology.
PHIVOLCS reported yesterday that it has recorded three volcanic quakes at Kanlaon volcano.
Alert Level 1 indicates a low-level unrest of the volcano, it added.
On Saturday, PHIVOLCS reported that Kanlaon volcano emitted moderate plumes that rose up to 500 meters tall, which drifted northeast.
Kanlaon Volcano on Negros Island has been on Alert Level 1 since 2020 and has been producing “low-frequency” volcanic earthquakes.
The Civil Aviation Authority of the Philippines has barred pilots from flying 10,000 feet from the surfaces of Kanlaon, Mayon, and Taal volcanoes due to continued unrest observed in these areas that could be hazardous to aircraft.
PHIVOLCS has advised the public to avoid entering the four kilometer-radius permanent danger zone around Kanlaon, as the possibility of sudden steam-driven, or phreatic explosions, may occur.
Kanlaon Volcano was observed to have emitted 1,089 tons of sulfur dioxide on June 5, and its edifice also remains inflated, PHIVOLCS further said in its bulletin.*
