PHIVOLCS reported that during 13-19 March white steam plumes periodically emitted from Mayon drifted mainly W and SW, and crater incandescence was visible nightly. Three phreatic events, recorded at 1510, 1518, and 1534 on 12 March, generated light-brown-to-grayish ash plumes that rose 500-1,000 m above the crater rim and drifted SW. Six phreatic events on 13 March, recorded at 0906, 0939, 0946, 0955, 1000, and 1059, produced ash plumes that rose 200-700 m and drifted W.
