Mayon Volcano erupts in Philippines, 1,325 families evacuated south of Manila
Synopsis
Key Takeaways
Mayon Volcano erupted on Sunday, 3 May, triggering the evacuation of thousands of residents from communities south of Manila, according to the Philippines government news agency. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has raised the alert level to three out of five, signalling that magma is near or at the surface and a hazardous eruption could follow within weeks.
Alert Level and Immediate Danger Zones
PHIVOLCS has enforced a strict 6-kilometre radius Permanent Danger Zone (PDZ) around the active crater, with danger zones potentially expanding to 8 kilometres depending on volcanic activity. All aircraft have been barred from flying close to the volcano. Alert level three, as defined by the institute, indicates that magma intrusion is imminent and activity may escalate rapidly.
Volcanic Activity Observed
The institute reported active lava effusion with lava flows across multiple gullies, accompanied by episodic minor strombolian activity and short-lived lava fountaining. Successive pyroclastic density currents (PDCs) and ashfall have been recorded on the southwestern slope of the volcano. Authorities have also flagged risks of rockfalls, landslides, avalanches, ballistic fragments, lahars during heavy rainfall, and moderate-sized explosions.
Families Affected and Water Supply Disruption
A total of 1,325 families have been affected by the eruption. Water supply is being rationed to 12 villages, including Quitago, Maguiron, Inamnan Pequeno, Iraya, San Francisco, Travesia, San Rafael, Inamnan Grande, Calzada, Morera, Poblacion, and Ilawod, according to the government news agency. The Department of Public Works and Highways has deployed water filtration units and sanitation teams to clear roads and assist affected residents.
Government Relief and Emergency Response
The Office of Civil Defence-Bicol is assessing immediate needs, including potable water, face masks — including N95 respirators — and medicine for respiratory illnesses. The Department of Social Welfare and Development is distributing hygiene kits, family food packs, and ready-to-eat meals at evacuation centres. Damage to livestock and farmlands is being assessed in coordination with the Department of Agriculture. Authorities are expected to continue monitoring volcanic activity closely, with the possibility of further evacuations if the alert level is raised.
