MANILA, Philippines — Heavy rains brought by the tail-end of a cold front have increased the dangers of lahar flowing “on all river channels” near the Mayon Volcano in Albay, the Philippine Institute of Volcanology and Seismology warned Saturday. In its advisory issued at 10:30 a.m. Saturday, the Phivolcs said the lava, ashfall and other pyroclastic density current (PDC) materials spewed by Mayon Volcano for the last two weeks could turn into lahar if the heavy rains continue. The Phivolcs said lahar and sediment-laden streamflows are possible “on all river channels draining the slopes of Mayon Volcano” especially in the villages of Buyuan, Missi, Mabinit, Basud, San Vicente, Buang, Quirangay and Masarawag-Maninila. “Communities and local government units beside these river systems are advised to be additionally vigilant and to move residents to high ground when heavy rains occur,” the Phivolcs said. “PHIVOLCS therefore warns of potential lahars and sediment-laden streamflows...that may be generated by heavy rainfalls brought about by the cold-front,” Phivolcs said.
