The lava flow coming from the Mayon Volcano’s summit crater has now reached 2,100 meters along Mi-si Gully and 1,300 meters along Bongga Gully, the state seismologist said on Thursday, June 29.
Based on its 24-hour monitoring, the Philippine Institute of Volcanology and Seismology (Phivolcs) said the continued feed lava flows caused debris to collapse at approximately 3,300 meters from the summit crater.
The Mayon Volcano also exhibited continued moderate degassing which produced plumes that rose 1,000 meters before it drifted toward west-northwest, north-northwest, and northeast.
Phivolcs’ Mayon Volcano Network also recorded slightly lower rockfalls, from 372 to 296.
Only one volcanic earthquake was recorded for the second-straight day.
The state seismologist said the country’s active volcano emitted 7 dome-collapse pyroclastic density currents (PDC) that lasted for 3 minutes and 2 lava front collapse PDC that generated light-brown plumes with 1,000 meters tall.
The Mayon Volcano also disharged sulfur dioxide which averaged 595 tonnes per day.
“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 said.
It reminded the public to remain vigilant against possible hazards such as PDCs, lahars, and sediment-laden streamflows along channels draining the edifice.
