Kanlaon Spews Ash In Sudden Night Eruption
Screengrab from PHIVOLCS-DOST
A sudden nighttime blast from Kanlaon Volcano sent residents on edge Monday after a moderately explosive eruption shot ash, glowing debris, and dangerous flows down its upper slopes.
The eruption occurred at 7:04 PM on February 26, 2026, according to DOST-PHIVOLCS, and lasted around two minutes based on seismic and infrasound data. The event produced a towering ash plume rising approximately 2,500 meters above the crater, drifting southwest and affecting areas downwind.
Monitoring teams reported incandescent volcanic fragments raining around the summit crater. More critically, pyroclastic density currents (PDCs)—fast, ground-hugging flows of hot gas, ash, and volcanic debris—swept down Kanlaon’s eastern and southeastern upper slopes, reaching up to 2 kilometers from the summit. These hazardous flows are capable of causing severe damage within seconds.
Following the initial explosion, Kanlaon continued to emit ash continuously, prompting PHIVOLCS to closely watch the volcano’s behavior for any sign of escalation.
The agency is now assessing monitoring data, including gas emissions, seismic activity, and crater observations within the next 24 hours to determine if Kanlaon’s current alert level should be raised. The volcano, known for its sudden and short-lived explosive events, remains under tight observation.
Communities around Negros Island were advised to stay vigilant, particularly those within or near the Permanent Danger Zone, as volcanic activity can intensify with little warning. Local governments may issue additional advisories depending on updated PHIVOLCS assessments.
Kanlaon remains one of the country’s most closely watched volcanoes, and authorities continue to monitor conditions as ash emission persists.
