(Eagle News)–Nine volcanic earthquakes were monitored at Kanlaon in 24 hours.
The Philippine Institute of Volcanology and Seismology said also monitored at the volcano, which remains on alert level 1, was sulfur dioxide emission, which was measured at an average of 656 tons on October 13.
A slight inflation of the lower and mid slopes since June 2020, and an inflation on the lower to mid slopes that began on June 21 “may indicate hydrothermal or magmatic processes occurring beneath the edifice,” PHIVOLCS said.
PHIVOLCS reminded the public that at alert level 1, the volcano is at “an abnormal condition and has entered a period of unrest.”
The local government units and the public were strongly reminded about the ban on the entry into the 4-kilometer radius Permanent Danger Zone “due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions.”
Civil aviation authorities were advised to caution pilots against flying close to the volcano’s summit.
“PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned,” PHIVOLCS said.
