Kanlaon Volcano’s seismic monitoring network recorded twenty nine (29) volcanic earthquakes during the past 24 hours. At 1:29 PM yesterday (December 27, 2015), an ash eruption from the active crater was detected by the seismic network as an explosion-type earthquake that was felt at Intensity II in Brgy. Cabagnaan, La Castellana, Sitio Guintubdan, Brgy Ara-al, and Brgy. Yubo, La Carlota City, and Brgy. Ilijan, Bago City. The event was accompanied by a rumbling sound heard in Brgy. Cabagnaan, La Castellana, Sitio Guintubdan, Brgy. Ara-al and Brgy. Yubo, La Carlota City. A visible eruption column that reached 1000m above the active crater before drifting southwest was observed, although this was reported by pilots to have reached 4500m above the summit. Traces of light ashfall were experienced in Sitio Guintubdan, Brgy. Ara-al, Brgy. Yubo, and Brgy. La Granja, La Carlota City, Brgy. Cabagnaan and Brgy. Sag-ang, La Castellana, Brgy. Miranda, Hinigaran, Negros Occidental, Municipality of Pontevedra, Negros Occidental, and reached as far as Nueva Valencia, Guimaras. Sulfuric odor was detected in La Carlota City Volcano Observatory. Before and after the eruption, background activity consisted of the emission of 50-1000m high steam plumes from the active vent.

Alert Level 1 status remains in effect over Kanlaon Volcano, which means that it is at an abnormal condition and is in a period of current unrest. 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 phreatic 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.
