The Department of the Interior and Local Government (DILG) has ordered local government units in Albay and Negros to prepare for possible lahar flows from Mayon Volcano and Mt. Kanlaon as Tropical Storm Ada brings heavy rains.
The agency said local chief executives may implement preemptive or mandatory evacuations if communities are deemed at high risk, and instructed LGUs to convene their disaster councils and conduct pre-disaster risk assessments.
High-risk areas around Mayon include several barangays in Daraga, Legazpi City, Sto. Domingo and Guinobatan, while residents near Kanlaon in parts of Negros Occidental and Negros Oriental were also placed on alert.
Meanwhile, the Philippine Institute of Volcanology and Seismology warned that increased rockfall, pyroclastic density currents and strong sulfur dioxide emissions indicate a higher chance of lava fountaining or moderate explosive eruption at Mayon.
Phivolcs reported 338 rockfall events, 72 pyroclastic density currents and the highest SO₂ emission in 15 years, signaling possible renewed volcanic activity.
