LEGAZPI CITY — The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded eight volcano-tectonic earthquakes in Mount Bulusan in Sorsogon on Tuesday morning, which may result in steam-driven or phreatic eruptions.
In an advisory, Phivolcs said the earthquakes were detected from 9:08 a.m. to 10:46 a.m., and occurred between 4 to 7 kilometers beneath the southern sector of the volcano.
“These changes in the condition of the volcano may progress into further unrest and potentially trigger steam-driven or phreatic eruptions from any of its active vents,” Phivolcs said in the advisory.
If the current monitoring parameters persist, the status of the volcano may be raised to Alert Level 1, Phivolcs said.
The volcano’s alert level was lowered from 1 to 0 (normal) on January 18.
On June 12, 2022, a phreatic eruption was detected by the Bulusan Volcano Network while the volcano was still under alert level 1 (abnormal condition).
