Bulusan volcano (Philippines): phreatic explosion on Friday
Saturday Jun 20, 2015 11:05 AM | DOOR: T
Another eruption, moderately strong, occurred 14:55 last Friday, producing an ash column that rose 1.5 km. The eruption was not directly visible, only parts of the ash plume could be spotted, but could be heard as rumbing in Monbon village.
Ash fell on five villages in Juban town and a small pyroclastic flow might have been generated. Phivolcs scientists think the eruption was another phreatic event, i.e. caused by steam not fresh magma. An analysis of the erupted ash is needed to clarify the origin of the eruption.
Alert Level 1 remains in effect over Bulusan volcano, and a 4 km radius exclusion zone is in place, as sudden phreatic explosions could (and likely will) occur any time again.
