Phivolcs Warns Lahar May Flow on Mayon Amid Heavy Rains
LIGAO CITY, Albay — The Philippine Institute of Volcanology and Seismology (Phivolcs) issued a warning about potential lahar flows on the slopes of Mayon Volcano as heavy rains continue to drench the Bicol region. The warning highlights the risk of volcanic debris being swept down by ongoing intense rainfall.
In a lahar advisory released early Thursday morning, Phivolcs noted that the combined effects of Severe Tropical Storm “Emong,” the remnants of Tropical Storm “Dante,” and the enhanced southwest monsoon (habagat) are likely to remobilize loose volcanic materials from past eruptions. These materials could cause dangerous sediment-laden streamflows.
Risk to Communities Near Mayon Volcano
Deborah Fernandez, a resident volcanologist at the Phivolcs Mayon Observatory, explained in a phone interview, “These sediment-laden streamflows may inundate, bury, or wash out downstream communities.” Residents near major river channels such as Miisi, Mabinit, Buyuan, and Basud are urged to stay alert. These waterways still carry pyroclastic deposits from the 2018 and 2023 eruptions.
Phivolcs also identified other high-risk drainage areas within Albay province, including Binaan, Anoling, Quirangay, Maninila, Masarawag, Muladbucad, Nasisi, Matanag, and Bulawan. Authorities continue to monitor these zones closely as heavy rains persist.
Local Response and Impact
In Guinobatan town, local officials have been clearing volcanic debris believed to have been washed down by recent rains. Barangay Masarawag experienced significant accumulation of these materials, which clogged roads and impaired access. Erosion and flooding have made some routes impassable, complicating travel and relief efforts.
The situation remains precarious as the weather system maintains heavy to torrential rainfall over the region. Residents living near Mayon’s slopes are advised to follow local government announcements and prepare for possible evacuation if conditions worsen.
