The seismic network around Bulusan Volcano (12°46.2’N, 124°03’E) detected nine (9) volcanic quakes during the 24-hour observation period. The steaming observation was hampered by clouds covering the volcano’s summit the whole day yesterday. No reading of sulphur dioxide emission was obtained due to rainy weather.
The alert status of Bulusan Volcano remains at Alert Level 1. The public is strongly advised not to enter the 4-kilometer radius Permanent Danger Zone (PDZ) because the area is at risk to sudden steam and ash explosions. Because of the prevailing wind direction, people residing in the northwest and southwest sectors of the volcano are reminded to take precautions against ashfalls. Civil aviation authorities must also warn pilots to avoid flying close to the volcano’s summit as ejected ash and volcanic fragments from sudden explosions may pose hazards to aircrafts. Furthermore, residents near valleys and river/stream channels should be vigilant against sediment-laden stream flows and lahars in the event of heavy and continuous rainfall. DOST-PHIVOLCS is closely monitoring Bulusan Volcano’s activity and any new significant development will be immediately relayed to all concerned.
