Eruption of Mayon Volcano Philippines. Photo: Shutterstock Authorities in the Philippines have raised the alert level at Mayon Volcano from Level 2 to Level 3 following a moderately explosive eruption on Friday, October 30, prompting an evacuation recommendation for communities near the volcano.
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the eruption occurred at 11:53 a.m. local time, sending a dense ash plume approximately 3,000 meters above the summit crater.
The plume rose rapidly before being carried west-southwest by moderate winds. PHIVOLCS warned that ashfall was expected in Daraga, Camalig, Guinobatan and neighboring municipalities in Albay province.
In its 12:30 p.m. bulletin, the agency said the increase to Alert Level 3 reflects a new phase of magmatic eruption, with a heightened possibility of lava flows and hazardous pyroclastic density currents (PDCs) affecting the upper and middle slopes of the volcano in the coming days and weeks.
Evacuation recommended within six kilometers
PHIVOLCS recommended the evacuation of the six-kilometer Permanent Danger Zone (PDZ) surrounding Mayon Volcano due to the risk of pyroclastic density currents, lava flows, rockfalls and other volcanic hazards.
Authorities also warned of possible lahars and sediment-laden flows along waterways draining the volcano. These dangerous flows can occur when volcanic material mixes with heavy rainfall and moves rapidly through river channels.
The agency also advised civil aviation authorities to warn pilots against flying close to the volcano's summit, as sudden eruptions could release ash capable of posing a serious hazard to aircraft.
Based on current wind conditions, ashfall is considered most likely on the southern side of the volcano.
Authorities monitor further volcanic activity
PHIVOLCS said it is closely monitoring Mayon and will communicate any significant developments to relevant authorities and communities.
The eruption has also prompted precautionary measures across Albay, including the suspension of classes and evacuation preparations. Residents have been urged to follow official instructions and avoid entering restricted areas.
Mayon is one of the Philippines' most active volcanoes, located in Albay province on the island of Luzon. Its activity poses a recurring threat to nearby communities, particularly those living along its slopes and surrounding river channels.
The latest alert upgrade does not mean a larger eruption is inevitable, but it indicates an increased risk of hazardous volcanic activity that authorities are preparing for.
