(Eagle News)–Several earthquakes and moderate plume emission were monitored at Kanlaon, the Philippine Institute of Volcanology and Seismology said in Monday, June 29.
PHIVOLCS said of the earthquakes at the volcano, which remains on alert level 1, 16 were volcano-tectonic earthquakes on the western flanks and four volcanic earthquakes in the summit area.
They were observed within 24 hours.
The moderate emission was of white steam-laden plumes that rose 300 meters.
Sulfur dioxide emission was measured at an average of 116 tons per day on June 27.
A slight deflation of the lower and mid slopes since January 2020 and inflation on the lower to mid slopes that began on June 21 “indicate hydrothermal or magmatic processes occurring beneath the edifice,” PHIVOLCS said.
PHIVOLCS reminded the public at that alert, Kanlaon has entered a “period of unrest,” and that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) should continue to be strictly prohibited.
Pilots should avoid flying close to the volcano’s summit.
“(The Department of Science and Technology)-PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned,” PHIVOLCS said.
