The seismic network at Bulusan Volcano (12°46.2’N, 124°03’E) recorded two (2) volcanic earthquakes during the past 24 hours.  Visual observation of the crater and known thermal vents was not possible due to thick clouds that covered the entire summit area.  No lahar event was observed. 

 

Bulusan Volcano’s status remains at Alert Level 1.This means that the source of activity is hydrothermal and shallow. However, no entry to the 4-kilometer radius Permanent Danger Zone (PDZ) is strongly advised, since the area is at risk to sudden steam and ash explosions. Due to the prevailing wind direction, residents 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 be hazardous to aircraft. Furthermore, people living near valleys and river/stream channels should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall. DOST-PHIVOLCS is closely monitoring Bulusan Volcano’s activity and any new significant development will be immediately relayed to all concerned.
