Kanlaon Volcano emitted more sulfur dioxide gas on Wednesday, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said Thursday.
In its bulletin, PHIVOLCS said 7,019 tonnes of sulfur dioxide gas were observed from the volcano on Wednesday, which is higher compared to the 4,121 tonnes recorded on Tuesday.
Two volcanic earthquakes were also monitored in Kanlaon Volcano. This is lower compared to the 31 volcano earthquakes reported in the previous bulletin.
The edifice of the volcano is still inflated, according to PHIVOLCS.
On Monday, an explosive eruption occurred at the summit vent of Kanlaon Volcano, producing a voluminous plume that rapidly rose to 4,000 meters.
Ashfall was reported and pyroclastic density currents or PDCs descended the slopes of the volcano.
Alert Level 3 remains over Kanlaon Volcano, which means there is a high level of volcanic unrest. Magmatic intrusion to shallow levels of the edifice is driving unrest, with indications that hazardous eruption could occur in weeks.
Possible hazards from the volcano include sudden explosive eruption, lava flow or effusion, ashfall, pyroclastic density current (PDC), rockfall, and lahars during heavy rains.
Danger zone was expanded to a radius of six kilometers from the summit crater or active vent.
A total of 39,258 persons or 9,942 families have been evacuated so far amid the activity of Kanlaon Volcano, according to the Office of Civil Defense (OCD) on Wednesday.
This is only around 46% of the 84,549 target evacuees within the six-kilometer danger zone.
