Smithsonian Institution Global Volcanism Network Bulletin v. 19, no. 12, December 1994 Bulusan (Philippines) Phreatic eruptions continue, but at a slower rate Bulusan Luzon, Philippines (12.77N, 124.05E) All times are local (= GMT + 8 hours) The phreatic eruptions that started in late November (Bulletin v. 19, no. 11) slowed in December, as evident from an apparent increase in intervals between ash explosions. There was no great change in seismic character, with only a few daily earthquakes plus a few episodes of low-frequency tremor, some of which were probably related to steam jetting. An explosion at 2213 on 31 December ejected ash and was accompanied by rumbling and lightning flashes observed at Salvacion Monitoring Station (South). Areas affected were Cogon, Tinampo, Monbon, Bagsanga. Another explosion at 0008 on 7 January caused light ashfall at Barangay Cogon, Irosin (5-6 km from summit). At 1344 on 10 January, an ash explosion sent a plume 1 km above the summit (1.5 km elevation) that drifted SSW. Very light ashfall was reported in villages up to 7 km SW.
