KANLAON VOLCANO BULLETIN 21 February 2021 08:00 A.M.
00 volcano icon for bulletin Kanlaon Volcano's monitoring network recorded seven (7) volcanic earthquakes during the 24-hour observation period. Moderate 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 587 tonnes/day on 17 February 2021. Ground deformation data from continuous GPS and electronic tilt measurements have been recording a slight inflation of the lower and middle 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 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.
