Kanlaon Volcano's monitoring network recorded three (3) volcanic earthquakes during the 24-hour observation period. Weak emission of white steam-laden plumes that rose 200 meters before drifting northwest was observed. Sulfur dioxide (SO2) emission was measured at an average of 187 tonnes/day on 19 November 2020. Ground deformation data from continuous GPS measurements indicate slight inflation of the lower and mid slopes since June 2020, while short-term electronic tilt monitoring on the southeastern flanks recorded inflation on the lower to mid slopes that began on 21 June 2020. These parameters may indicate hydrothermal or magmatic processes occurring beneath the edifice.

 

DOST-PHIVOLCS would like to remind the public that Kanlaon Volcano is at Alert Level 1, which means that it is at an abnormal condition and has entered a period of unrest. The local government units and the public are strongly reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) must be 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.
