MANILA, Philippines — Mount Kanlaon on Negros Island remained under Alert Level 2, meaning the volcano is “undergoing a moderate level of unrest,” on Thursday, November 16, after the Philippine Institute of Volcanology and Seismology recorded 217 volcanic earthquakes over the past 24 hours.

While Phivolcs said “no degassing activity was observed during times when the summit crater was visible,” it added that Kanlaon’s activity indicates the “probable intrusion of magma at depth(s) which may or may not lead to a magmatic eruption.”

The agency also said ground deformation data “indicate inflation of the edifice since Deceber 2015” while sulfur dioxide emissions measured an average of one ton per day on September 6 this yeer.

Local government units have been reminded to strictly implement the four-kilometer radius Permanent Danger Zone while pilots are advised not to fly near the volcano’s summit.
