Kanlaon Volcano’s monitoring network recorded three (3) volcanic earthquakes duringKanlaon Volcano’s monitoring network recorded three (3) volcanic earthquakes duringthe 24-hour observation period. No steaming to moderate emission of white steamladenplumes that rose 300 meters before drifting southwest and northwest wasobserved. Sulfur dioxide (SO2) emission was measured at an average of 1230tonnes/day on 27 March 2021. Ground deformation data from continuous GPS andelectronic tilt measurements have been recording a slight inflation of the lower andmiddle slopes since June 2020. These parameters may indicate hydrothermal,tectonic, or deep-seated magmatic processes occurring deep beneath the edifice.DOST-PHIVOLCS would like to remind the public that Kanlaon Volcano is at AlertLevel 1, which means that it is at an abnormal condition and has entered a period ofunrest. The local government units and the public are strongly reminded that entry intothe 4-kilometer radius Permanent Danger Zone (PDZ) must be strictly prohibited dueto 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’ssummit as ejecta from any sudden phreatic eruption can be hazardous to aircraft.DOST-PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any newdevelopment will be relayed to all concerned.
