Phivolcs raises Alert Level 1 on Kanlaon Volcano 0 SHARES Share it! Share TweetBy Alexandria Dennise San JuanThe Philippine Institute of Volcanology and Seismology (Phivolcs) raised on Wednesday the alert status of Kanlaon Volcano from Alert Level 0 to Alert Level 1 after an increase in seismic activity was observed in the past days. The bureau pointed out that these parameters indicate that volcanic processes are “underway deep beneath the edifice” which may be caused by “deep-seated degassing or hydrothermal activity or magmatic intrusion.”Following the raising of Kanlaon’s danger level, Phivolcs reminded local government units and the public that entry into the four-kilometer radius Permanent Danger Zone must be “strictly prohibited” due to possibilities of sudden and hazardous phreatic eruptions. Phivolcs said civil aviation authorities should advise pilots to avoid flying close to the volcano’s summit as ejecta from any sudden phreatic eruption can be hazardous to aircraft. Apart from Kanlaon, the state volcanology agency is also closely monitoring other active volcanos in the country including Taal and Mayon which are currently at Alert Level 2 or at a “moderate level of unrest.”
