Bulusan Volcano area a no-fly zone

Bulusan Volcano’s status remains at Alert Level 1, which means entry to the 4-kilometer radius Permanent Danger Zone is strictly prohibited since the area is at risk to sudden steam and ash explosions, the Philippine Institute of Volcanology and Seismology posted Wednesday.

For the past 24 hours, PHIVOLCS said, seismic observation at Bulusan Volcano revealed the occurrence of 1 volcanic earthquake. No other significant volcanic activity was observed since the February 21 ash explosion.

PHIVOLCS has reminded residents in the northwest and southwest sectors of the volcano to take precautions against ashfalls. Civil aviation authorities were also urged to warn pilots to avoid flying close to the volcano’s summit as ejected ash and volcanic fragments from sudden explosions may be hazardous to aircraft.

If possible, aircrafts should avoid flying on the western side of the volcano as volcanic debris are likely to be carried in this direction by the prevailing winds, PHIVOLCS noted.

People living near valleys and river channels should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall, it said.
