The Philippine Institute of Volcanology and Seismology (Phivolcs) reported on Saturday, Jan. 4, that it recorded a total of 27 volcanic earthquakes at Kanlaon Volcano.
During its 24-hour monitoring period, from 12 a.m. on Friday to 12 a.m. on Saturday, Phivolcs observed 27 volcanic earthquakes as Kanlaon Volcano remained under Alert Level 3, indicating intensified unrest or magmatic activity.
Phivolcs also noted that sulfur dioxide (SO2) emissions were recorded at 5,840 tons per day on Jan. 3.
A 750-meter tall plume was observed, attributed to continuous degassing, drifting northwest and west.
Phivolcs has recommended evacuation from the six-kilometer radius around the volcano's summit.
The agency also emphasized that flying aircraft close to the volcano should be prohibited.
Phivolcs warned that possible hazards such as sudden explosive eruptions, lava flow or effusion, ashfall, pyroclastic density currents (PDC), rockfall, and lahars during heavy rains could occur.
