Awareness and Preparedness
|KANLAON VOLCANO BULLETIN 21 March 2017 08:00 A.M.|
Kanlaon Volcano’s seismic monitoring network recorded four (4) volcanic earthquakes during the past 24 hours. No steaming was observed during times when summit crater was visible. Sulfur dioxide (SO2) emission was measured at an average of 1 tonne per day on February 25, 2017. Ground deformation data from continuous GPS measurements as of January 27, 2017 indicated no significant change of the Kanlaon edifice since August 2016.
Alert Level 1 status remains in effect over Kanlaon Volcano, which means that it is currently in a state of unrest probably driven by hydrothermal processes that could generate steam driven or phreatic eruptions. The local government units and the public are reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or minor ash eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as airborne ash from a sudden 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.
