ALERT Level 1 (abnormal) status prevails over Kanlaon Volcano.
Based on the advisory of the Philippine Volcanology and Seismology (Phivolcs), alert level 1 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 to avoid entry into the four-kilometer radius permanent danger zone (PDZ) due to perennial hazards of rock falls, avalanches, sudden outgassing and steam-driven or phreatic eruption at the summit area.
Phivolcs added that 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. The Department of Science and Technology (DOST)-Phivolcs is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned
Phivolcs stated that monitoring network did not detect any volcanic earthquake during the 24-hour observation period. Sulfur dioxide (SO2) emission was measured at an average of 79 tonnes/day on 15 June 2019.
Ground deformation data from latest continuous GPS measurements indicate slight deflation of the edifice. (TDE)
