00 volcano icon for bulletin Kanlaon Volcano's seismic monitoring network recorded one hundred four (104) volcano-tectonic earthquakes on the western flanks during the 24-hour observation period. One (1) earthquake at 5:07 AM yesterday was recorded at M3.0 by the Philippine Seismic Network and was felt at Intensity II in La Carlota City, Negros Occidental. Activity at the vent consisted of weak emission of white steam-laden plumes that rose 300 meters before drifting northwest and southeast. Sulfur dioxide (SO2) emission was measured at an average of 438 tonnes/day on 13 June 2020. 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 continuing deflation on the lower slopes but inflation on the mid slopes since April 2020. These parameters indicate that hydrothermal or magmatic activity is 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.
