LEGAZPI CITY—Continuous flow of lava out of Mayon’s summit crater was relatively quiet and non-explosive during the past 24-hour observation period, said the Philippine Institute of Volcanology and Seismology (Phivolcs) in a bulletin issued yesterday morning.
Lava flow has advanced by some 200 meters downslope and has reached the 600-meter elevation, Phivolcs explained.
Alert level 3 remained in effect so that residents within the 6-kilometer Permanent Danger Zone (PDZ) and just beyond the PDZ in the southeast sector facing Bonga Gully—especially Barangays Mabinit, Bonga, Matanag and Buyuan in the southeast—and Miisi to the south have been advised to be vigilant.
Phivolcs warned that rockfalls, lava flows and small rock avalanches or pyroclastic flows may affect these areas.
Residents near areas facing the south-southeast portion of the volcano and within 7 km of the crater have been advised to be prepared for evacuation. Ephraim Aguilar, PDI Southern Luzon Bureau
