The summit crater of Mayon Volcano has spewed lava flow and its volcanic activities have increased in the past 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Monday.
In its<a href="https://www.phivolcs.dost.gov.ph/index.php/volcano-hazard/volcano-bulletin2/mayon-volcano/18257-mayon-volcano-bulletin-12-june-2023-8-00-am" target="_blank" rel="noopener"> 8 AM bulletin</a>, Phivolcs said the law flow spewed at around 7:47 on Sunday which formed two lobes of lava and shed some lava debris within 500 meters of Mi-Isi south, Bonga southeastern, and Basud gullies.
The said lava flow activity was accompanied by weak seismic activity and slight swelling of the upper portions of the edifice.

According to the state seismologists,&nbsp; it recorded a total of 21 volcanic earthquakes and 260 rockfall events in Mayon over the past 24 hours.
The Mayon Volcano emitted 642 tonnes of sulfur dioxide since Sunday and produced three dome-collapse pyroclastic density currents (PDC) that lasted for two to four minutes.
Alert Level 3 is still in effect over Mayon Volcano as it is presently in a relatively high level of unrest.
"Magma is at the crater and hazardous eruption is possible within weeks or even days," Phivolcs said.
The state seismologist advised the public to be vigilant against the danger of PDCs, lava flows, rockfalls, and other volcanic hazards.
As of Monday, local government units of Albay province have evacuated over 11,000 residents living inside the six-kilometer danger zone of Mount Mayon.
