MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) on Sunday said that it had recorded one volcanic earthquake and 177 rockfall events in Mayon Volcano, which remains under Alert Level 3. Based on its 8 a.m. bulletin, Phivolcs said the volcanic earthquake and rockfall events were recorded over the last 24 hours, as Mayon Volcano continues to have 'intensified unrest or magmatic unrest.' Mayon released 1205 tons of sulfur dioxide on June 10. A fair crater glow was also observed as its plumes were generally seen drifting east while its edifice was inflated.
