Mayon Volcano emits lava; rockfall events increase — PHIVOLCS
Very slow lava flow from the summit of Mayon Volcano for the fifth night was observed early Friday morning by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
"Very slow lava effusion from the summit crater of Mayon Volcano continues for the fifth night, generating an increasing amount of rockfall and pyroclastic density current (PDC) activity," the agency said.

The images posted, PHIVOLCS added, were taken from the Mayon Volcano Observatory at 11:15 p.m. on June 15, 2023 while the infrared image less than an hour after.
"Photo taken on 15 June at 11:54 PM; aperture f/4; exposure time 0.8 sec; ISO 1600. FLIR (forward-looking infra-red) image taken on 16 June at 12:21 AM."
The PHIVOLCS also posted a time-relapse video showing a PDC event generated by the lava dome collapse at the summit of the volcano that occurred at 11:18 p.m. on Thursday. The video was take from the Paulog, Ligao Observation Station (VMLI) IP camera.
"The PDC event lasted 6 minutes based on the seismic record; Mayon's edifice was largely obscured. This was the largest PDC recorded so far since the first generated on 8 June 2023," the agency posted.
Earlier, PHIVOLCS recorded two volcanic earthquakes and 306 rockfall events in Mayon Volcano in Albay, which remains under Alert Level 3.
These activities were less than the seven volcanic earthquakes and 309 rockfall events logged the previous day.
Mayon Volcano also released 193 tons of sulfur dioxide on Wednesday, June 14. A fair crater glow and "very slow" effusion of lava from the volcano's summit were observed. Plumes 700 meters tall were seen drifting in a northwestward direction.
