Seven volcanic earthquakes and 309 rockfall events were recorded in Mayon Volcano in the past 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Wednesday, June 14.
This is up from the preceding day’s one volcanic quake and 221 rockfall events.
In its 8:00 a.m. bulletin, the Phivolcs said a very slow lava effusion from the summit crater is still observed, while a fair crater glow “banaag” and and an incandescent rockfall shed were also observed.
Seven dome-collapse pyroclastic density current (PDC) events that lasted for four minutes were recorded, higher than the one two-minute PDC in the previous day.
