The Philippine Institute of Volcanology and Seismology (PHIVOLCS) on Saturday reported that they detected 178 volcanic earthquakes in Mt. Bulusan in the last 24 hours, higher compared to 149 volcanic earthquakes on Friday.,The state-seismology bureau said in its 5 a.m. bulletin that Bulusan released 613 tonnes of sulfur dioxide with moderate plume emissions of 150 meters tall on the west-northwest drift.,They also reported that the ground deformation on the volcano edifice is inflated.,PHIVOLCS also reminded local government units and the public that entry into the 4-kilometer radius Permanent Danger Zone is prohibited and surveillance should be carried out in the 2-kilometer Extended Danger Zone due to the rising possibility of a sudden and dangerous phreatic eruption.,Phivolcs have urged civil aviation authorities to caution pilots to avoid flying near the peak of the volcano since ash from a rapid phreatic eruption can be dangerous to aircraft.,“People living within valleys and along river/stream channels especially on the southeast, southwest and northwest sector of the edifice should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall should a phreatic eruption occur,” it also said.
