LAHAR ADVISORY FOR MAYON VOLCANO UNDER TROPICAL STORM PAENG (NALGAE)
28 October 2022
Based on the Tropical Cyclone Bulletin # 11 issued at 5:00 PM today by the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA), tropical storm “PAENG” is expected to bring heavy to intense, with at times torrential, rains over Bicol Region and Eastern Visayas this afternoon until tomorrow morning. These rains could generate volcanic sediment flows or lahars, muddy streamflows or muddy run-off in rivers and drainage areas of Mayon Volcano. DOST-PHIVOLCS thus strongly recommends increased vigilance and readiness of communities in pre-determined zones of lahar and related hazards on this volcano. Prolonged and heavy rainfall may generate non-eruption lahars along river/stream channels draining the Mayon edifice. Potential lahars and sediment-laden streamflows may occur along the Miisi, Binaan, Anoling, Quirangay, Maninila, Masarawag, Muladbucad, Nasisi, Mabinit, Matan-ag, and Basud, Bantayan Channels in Albay Province. Mayon lahars can threaten communities along the middle and lower slopes and downstream of these channels with inundation, burial and wash out.
DOST-PHIVOLCS strongly advises the communities and local government units of the above identified areas of risk to continually monitor the typhoon conditions and take pre-emptive response measures for their safety from “PAENG.”
