Phivolcs warns treks to Bulusan Volcano after 5 quakes in 24-hour period; reminds public to avoid 4-km permanent danger zone


DOST-PHIVOLCS is informing all concerned authorities and the public on recent activities at Bulusan Volcano.

In the last 24-hour observation period, the Bulusan Volcano Network recorded five (5) volcanic earthquakes.

In view of the possibility of sudden steam-driven or phreatic explosion from the summit crater or from vents on the Bulusan upper slopes, DOST-PHIVOLCS strongly reminds the public and local government units that the 4-kilometer radius Permanent Danger Zone (PDZ) should be avoided at all times as a precaution.

In particular, all treks to the summit must be avoided due to the increased risk of phreatic activity.

DOST-PHIVOLCS is keeping close watch and evaluating the status of the volcano and will inform all concerned of any further developments.
