Kanlaon Volcano's seismic monitoring network recorded nine hundred and fifty-seven (957) volcanic earthquakes, nine hundred and thirty-four (934) of which are microearthquakes, during the past 24 hours. During times when the summit was visible, moderate emission of white steam-laden plumes were observed rising to 300 meters from the summit before drifting to the northeast, southwest and northwest. Ground deformation data from continuous GPS measurements indicate slight inflation of the edifice since December 2015. Sulfur dioxide (SO2) emission was measured at an average of 432 tonnes/day on 20 December 2017.

Alert Level 2 status prevails over Kanlaon Volcano, which means that the volcano is undergoing a moderate level of unrest. There is probable intrusion of magma at depth which may or may not lead to a magmatic eruption. The local government units and the public are strictly 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 ejecta from any sudden phreatic 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.
