MAYON Volcano spewed plumes reaching 2,500 meters from its summit crater, recorded new pyroclastic density currents (PDCs), more rockfall events and volcanic earthquakes over the past 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Friday.
Alert level 3 is still up over Mayon, which means that it is currently in a relatively high level of unrest as magma is at the crater, Phivolcs said.
The plumes were higher than the 1,000 meters produced on Thursday.
A total of seven dome-collapse PDCs, 284 rockfall events and two volcanic earthquakes were also registered in the last 24 hours.
“Very slow effusion of lava from the summit crater of Mayon Volcano continued to feed lava flows and collapse debris on the Mi-isi and Bonga gullies,” according to Phivolcs statement.
The lava flows have reached 2,230 meters along Mi-isi (south) gully, which is higher compared to the 2,100 meters recorded on Thursday.
Collapsed debris estimated at 3,300 meters were ejected from the crater.
