MANILA, Philippines — Kanlaon Volcano on the island of Negros continues its restlessness as it registered three volcanic earthquakes in a span of 24 hours.

In an advisory on Sunday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said the volcano’s sulfur dioxide emission reached an average of 336 tonnes/day on Tuesday, Nov. 24.

A “slight inflation” of the lower and mid slopes of Kanlaon was also recorded since June, Phivolcs noted.

Local government units and the public are strongly reminded that entry into the four-kilometer radius Permanent Danger Zone must be strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions, Phivolcs said.
