No volcanic earthquake was recorded in Mayon Volcano but the summit crater continues to effuse lava down the slope at a very slow rate, the state seismologist reported on Monday.
Based on its latest 24-hour monitoring, the Philippine Institute of Volcanology and Seismology (Phivolcs) said that the law flow has advanced to 1,500 meters from the summit crater, causing debris to collapse on Mi-isi and Bonga Gullies.
Phivolcs also observed that the Mayon Volcano had 5 dome-collapse pyroclastic density currents (PDC) with 3 minutes long and 265 rockfall events.
The volcano emitted 889 tonnes of sulfur dioxide since June 18 and steam-laden plumes that reached the height of 600 meters before drifting to the general west.
The steam-laden plumes were higher as compared to the 100 meters recorded on Sunday.
The state seismologist said its monitoring showed that the Mayon Volcano is still inflated, especially in the northwest and southeast side.
“Alert Level 3 is maintained over Mayon Volcano, which means that it is currently in a relatively high level of unrest as magma is at the crater and hazardous eruption within weeks or even days is possible,” Phivolcs noted.
It reiterated its advice that the public should heighten their vigilance against possible pyroclastic density currents, lahars, and sediment-laden streamflows.
Aircrafts are still refrained from flying close to the volcano’s summit due to the hazards of the ashes.
