MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) said Thursday it is closely monitoring Bulusan Volcano in Sorsogon following an increase in seismic activities. “The seismic parameters indicate shallow hydrothermal activity is underway and may lead to steam-driven or phreatic eruption,” the institute said. Last week, the Phivolcs also reported increased activities at Bulusan. Bulusan is under Alert Level 1, which means it is in a state of low-level unrest, with an increased likelihood of stream-driven or phreatic eruptions.
