Bulusan Volcano’s (12°46.2’N, 124°03’E) seismic network detected a total of twenty (20) volcanic earthquakes during the past 24 hours.  The summit of the volcano was cloud-covered the whole day yesterday.  Early this morning, weak to very weak  emission of white steam from the volcano’s crater and known thermal vents was observed creeping downslope towards southwest.  Yesterday’s measurement of Sulfur Dioxide (SO2) emission rate yielded an average value of 96 tonnes day.

The status of Bulusan Volcano is still rated at Alert Level 1.  The public is strongly advised not to enter inside the 4-kilometer radius Permanent Danger Zone (PDZ) because it may be affected by sudden steam explosions.  People residing near valleys and streams are also advised to be vigilant against sediment-laden stream flows in the event of heavy and continuous rainfall.  Due to the prevailing wind direction, residents located in the northwest and southwest sectors of the volcano are advised to take precautions against ashfalls.  Civil aviation authorities must advise pilots to avoid flying close to the volcano’s summit as ejected ash and volcanic fragments from sudden explosions may pose hazards to aircrafts.  PHIVOLCS-DOST is closely monitoring Bulusan Volcano’s activity and any new significant development will be immediately posted to all concerned.
