Four volcanic quakes, emission of sulfur dioxide monitored at Kanlaon; alert level 1 stays

(Eagle News)–Four volcanic earthquakes were monitored at Kanlaon in 24 hours.

The Philippine Institute of Volcanology and Seismology said sulfur dioxide emission was also monitored at the volcano, which remains on alert level 1.

PHIVOLCS said the sulfur dioxide emission was measured at an average of 656 tons  on  October 13.

A slight inflation of the lower and mid slopes since June, 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 the volcano is at alert level 1, which means that it is at an “abnormal condition and has entered a period of unrest.”

The local government units and the public were reminded about the ban on the entry into the 4-kilometer radius Permanent Danger Zone.

Civil aviation authorities were also told to caution pilots against flying close to the volcano’s summit as “ejecta from any sudden phreatic eruption can be hazardous to aircraft.”

“PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned,” PHIVOLCS said.
