The Philippine Institute of Volcanology and Seismology (Phivolcs) on Thursday said that no volcanic earthquake was recorded in Mayon Volcano in Albay province from 5:00 AM on June 21 to 5:00 AM on June 22.
But the Mayon Volcano continued to exhibit high levels of volcanic activity as Phivolcs detected 299 rockfall events and 8 dome-collapse pyroclastic density currents (PDC).
The state seismologist said the lava flow has advanced to a length of 2.5 kilometers on Mi-isi Gully and 1.8 kilometers on Bonga Gully.
The said lava caused the debris to collapse along the two gullies within 3.3 km from the Volcano’s summit crater.
Sulfur dioxide flux coming from the volcano averaged 574 tonnes a day while the steam-laden plume reached 750 meters tall before it drifted southwest.
Phivolcs said its monitoring showed that Mayon Volcano’s edifice remains inflated.
Alert Level is still raised as "as magma is at the crater and hazardous eruption within weeks or even days is possible."
The state seismologist continuously reminds the public against hazards such as rock falls or landslides or avalanches, ballistic fragments, lava flows and lava fountaining, pyroclastic density currents, moderate-sized explosions, and lahars during heavy and prolonged rainfall.
