MAYON LOGS LARGEST PYROCLASTIC FLOW #MayonVolcano generated its largest pyroclastic density current (PDC) to date at 10:35 a.m. Monday, sending volcanic material down the Mi-isi Gully for about four kilometers, #PHIVOLCS reported. The PDC produced a brownish ash plume more than two kilometers high that drifted southwest, causing ashfall in several barangays of Camalig and Guinobatan.
