THE PHILIPPINE Institute of Volcanology and Seismology (Phivolcs) yesterday raised the alert for Kanlaon Volcano to level 2 as moderate unrest has been recorded. In its bulletin issued morning of Nov. 15, Phivolcs said the seismic monitoring network recorded a total of 279 deep volcanic earthquakes in the past 24 hours. “Since 18 August 2017, the number of volcanic earthquakes detected per day has continued to increase,” the agency said. It also said that while there has been no visible steaming from the active vent this year, “increased unrest could possibly develop into steam-driven or phreatic eruptions at the summit.” With the alert level at 2, Phivolcs reminded the local government units and the public to strictly observe the no-entry rule within the four-kilometer radius Permanent Danger Zone (PDZ). Civil aviation authorities have also been advised to warn pilots to avoid flying close to the volcano’s summit.
