Kanlaon Volcano’s seismic monitoring network recorded ten (10) volcanic earthquakes during the past 24 hours. At around 12:30 PM yesterday (December 30, 2015), one (1) low-energy ash eruption from the active summit crater was reported by residents of Brgy. Cabagnaan and Brgy. Sag-ang, La Castellana. However, the event was not detected by the seismic network, indicating a shallow volcanic source. Dirty white ash plumes that reached 100 meters above the summit before slowly drifting southwest, were observed. Apart from this, background activity at the active crater was not observed due to thick rain clouds covering the summit.

Alert Level 1 status remains in effect over Kanlaon Volcano, which means that it is currently in a state of unrest driven by hydrothermal processes that could generate more minor eruptions. The local government units and the public are reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or minor ash eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as airborne ash from a sudden eruption can be hazardous to aircraft. DOST-PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned.
