Phivolcs issues lahar advisory for Mayon due to Dante, Emong

The Philippine Institute of Volcanology and Seismology (Phivolcs) issued a lahar advisory for Mayon Volcano due to Tropical Storm Dante, Severe Tropical Storm Emong, and the southwest monsoon.

Heavy rains could generate volcanic sediment flows or lahars in rivers and drainage areas on Mayon Volcano, Phivolcs said, advising communities near the volcano to increase vigilance as potential lahars and sediment-laden streamflows may inundate downstream communities.

Communities and local government units were advised to monitor rainfall conditions and take preemptive safety measures, with residents living near major channels including Miisi, Mabinit, Buyuan, Basud, Binaan, Anoling, Quirangay, Maninila, Masarawag, Muladbucad, Nasisi, Matanag, and Bulawan remaining vigilant.

Local officials in Guinobatan town cleared what was believed to be volcanic debris that had spilled onto roads in Barangay Masarawag, where erosion and flooding rendered access roads to the town proper impassable.

As of Thursday morning, Pagasa raised signal no. 3 over parts of Pangasinan and La Union, with signals no. 2 and no. 1 hoisted across various regions in northern Luzon.

Tropical Storm Dante is expected to leave the Philippine area of responsibility on Thursday afternoon or evening, while Severe Tropical Storm Emong is projected to reach typhoon intensity before landfall in Ilocos on Thursday night or early Friday.
