Alert level 3 remains at Mayon Volcano; 308 rockfall events recorded
The restive Mayon Volcano remains at alert level 3 due to a relatively high level of unrest, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Saturday morning, June 24.

The possibility of a hazardous eruption within weeks or days is not out of the picture since magma is seen in the volcano's crater. "In the past 24-hour period, very slow effusion of lava from the summit crater of Mayon Volcano continued to feed lava flows and collapse debris on the Mi-isi (south) and Bonga (southeastern) gullies. The lava flows have advanced to maximum lengths of two thousand five hundred (2500) meters and one thousand eight hundred (1800) meters along Mi-isi and Bonga gullies, respectively, from the summit crater while collapse debris have deposited to three thousand three hundred (3300) meters from the crater," Phivolcs said. There was also one dome-collapse pyroclastic density current that lasted for three minutes, 308 rockfall events, and two volcanic earthquakes recorded by the Mayon Volcano Network. Mayon Volcano's continuous moderate degassing from the summit crater also produced steam-laden plumes that rose 600 meters before drifting southwest. Its sulfur dioxide emissions also averaged 744 tonnes a day on Friday, June 23, Philvolcs said. The agency reiterated the hazards of entering the six-kilometer-radius permanent danger zone and flying any aircraft on top of the volcano.
