Kanlaon Volcano's seismic monitoring network recorded four (4) volcanic earthquakes during the 24-hour observation period. Moderate emission of white steam-laden plumes that rose 300 meters before drifting southwest was observed. Ground deformation data from continuous GPS measurements indicate a slight deflation of the lower and mid slopes since January 2020. Short-term electronic tilt monitoring on the southeastern flanks recorded pronounced inflation of the upper slopes at the end of January 2020. These parameters indicate that hydrothermal or magmatic activity is occurring deep beneath the edifice.

Alert Level 1 (abnormal) status prevails over Kanlaon Volcano, 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.
