Increased seismic activity was once again observed at Bulusan Volcano in Sorsogon, as the Philippine Institute of Volcanology and Seismology (Phivolcs) warned of another possible eruption “within the next few hours to next few days.”
Phivolcs, in its volcano bulletin on Tuesday, June 21, said it has recorded 80 volcanic earthquakes at Bulusan Volcano in the past 24 hours.
It reminded the public that the active volcano remains under Alert Level 1, which means it is still in an “abnormal” condition.
Bulusan Volcano’s status has been raised from Level 0 to Level 1, following a phreatic eruption on June 5. It had another phreatic eruption on June 12.
Phivolcs said entry into the four-kilometer permanent danger zone is strictly prohibited due to possible sudden steam-driven or phreatic eruptions.
Meanwhile, the public is advised to remain vigilant when entering the two-kilometer extended danger zone, which is in the southeast sector of Bulusan Volcano.
Furthermore, people living within valleys and along river/stream channels especially on the southeast, southwest and northwest sector of the edifice were advised to be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall should another phreatic eruption occurs.
