BULUSAN VOLCANO BULLETIN
18 August 2021
This serves as notice for the lowering of the alert status of Bulusan Volcano from Alert Level 1 (Low-Level Unrest) to Alert Level 0 (Normal).
Bulusan Volcano has returned to normalcy following a general decline in monitoring parameters. This is supported by the following observations:
In view of the above, PHIVOLCS-DOST is now lowering the alert status of Bulusan Volcano from Alert Level 1 to Alert Level 0. This means that observational parameters have returned to baseline levels and no magmatic eruption is foreseen in the immediate future. However, in the event of a renewed increase in any one or combination of the above monitoring parameters, the alert status may step up once again to Alert Level 1. The public is reminded to avoid entry into the 4-km Permanent Danger Zone or PDZ due to perennial hazards of rockfalls, avalanches and sudden steam-driven or phreatic eruption from any of the active vents which may occur without warning. Furthermore, people living in valleys and active river channels are cautioned to remain vigilant against sediment-laden streamflows and floods in the event of prolonged and heavy rainfall. PHIVOLCS-DOST is closely monitoring Bulusan’s activity and any new development will be immediately communicated to all concerned.
This will be the last bulletin for Bulusan Volcano until new developments in monitoring parameters occur.
