LEGAZPI CITY, Nov. 12 -- Mount Bulusan in Sorsogon province belched on Friday morning a voluminous ash plume 700 meters above its crater rim that drifted and covered villages in the southwest flank of the volcano, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
Phivolcs said the phreatic explosion occurred at 6:59 a.m., sending light gray ash column that was accompanied by rumbling sounds, a typical characteristic of Bulusan's restive state.
Ash falls were reported in the villages in the towns of Irosin and Juban.
