THE Philippine Institute of Volcanology and Seismology (Phivolcs) continues to monitor Kanlaon Volcano.

Kanlaon Volcano's monitoring network recorded 33 volcanic earthquakes during the 24-hour observation period, Phivolcs said.

Moderate emission of white steam-laden plumes that rose 700 meters before drifting southwest was observed.

Sulfur dioxide (SO2) emission was measured at an average of 1130 tonnes/day on February 13, 2021. Ground deformation data from continuous GPS and electronic tilt measurements have been recording a slight inflation of the lower and middle slopes since June 2020.

These parameters may indicate hydrothermal, tectonic, or deep-seated magmatic processes occurring deep beneath the edifice, Phivolcs said.

The four-kilometer radius Permanent Danger Zone must be strictly prohibited, Phivolcs warned.
