Based on its Tropical Cyclone Advisory # 5 issued at 11:00 AM today (November 30, 2019), the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) forecasts that the Bicol Region will be experiencing moderate to heavy rains and thunderstorms starting Monday (December 2, 2019) due to Typhoon “KAMMURI”.

In view of the above, DOST-PHIVOLCS strongly recommends vigilance and readiness of communities in pre-determined zones of lahar hazards in Bulusan Volcano. Prolonged and heavy rainfall may cause excessive erosion of existing pyroclastic deposits in the upper slopes of Bulusan Volcano, which can trigger lahars in rivers draining the southeastern, southwestern and northwestern flanks. Potential lahars can threaten downstream communities along the Malunoy (Patag), Mapaso, Cadac-an, Tinampo and Cogon Rivers in Irosin and the Añog-Rangas River in Juban. Alert Level 1 remains in effect over Bulusan Volcano. DOST-PHIVOLCS also reiterates that entry into the four kilometer-radius Permanent Danger Zone should be avoided due to the possibility of sudden and hazardous steam-driven or phreatic eruption, rockfall, landslide, and lahars. DOST-PHIVOLCS is closely monitoring Bulusan Volcano’s condition and any new development will be relayed to all concerned.
