Kanlaon Volcano in Negros Island remained under Alert Level 2 on Tuesday, September 30, as the Philippine Institute of Volcanology and Seismology (Phivolcs) reported heightened activity over the past 24 hours.
In its latest summary observation report, Phivolcs said that Kanlaon continues to log increased unrest, with 31 volcanic earthquakes recorded from only seven quakes in the previous monitoring period.
Sulfur dioxide emissions – a colorless gas from magma releasing dissolved gases – also rose to 1,141 tons per day from 1,027 tons. Plumes reached 150 meters from the summit before drifting southwest.
Ground deformation is still inflated, which means that the ground around the volcano is swelling or bulging outward.
Alert level 2 remains raised on Kanlaon. This signifies moderate unrest with evidence of magma involvement.
Phivolcs warned of potential hazards, including sudden steam-driven or phreatic eruptions and possible magmatic activity.
Authorities reiterated that entry into the four-kilometer permanent danger zone is strictly prohibited, and flying any aircraft near the volcano should not be allowed. /das
