Kanlaon Volcano Records 23 Earthquakes, PHIVOLCS Warns of Ongoing Unrest

Seismic Activity and Ongoing Unrest

PHIVOLCS reported that the 23 recorded tremors were primarily volcano-tectonic earthquakes, indicating magma movement beneath Kanlaon’s surface. The agency also noted that faint crater glow, increased gas emissions, and localized ground deformation suggest a continuous supply of magma.

“Kanlaon Volcano remains in a state of unrest,” PHIVOLCS stated. “The recorded volcanic earthquakes suggest that magma is moving within the volcano, which could lead to an eruption.”

The Alert Level remains at 1, meaning that Kanlaon is experiencing abnormal activity and has a higher likelihood of eruptive events than usual. PHIVOLCS reminds the public that sudden explosions and ashfall remain possible, and people should avoid entering the 4-kilometer permanent danger zone (PDZ).

Potential Hazards and Community Preparedness

Authorities have warned that continued unrest could lead to hazardous eruptions, which may include:

• Ashfall affecting nearby cities and agricultural areas
• Lava flows and pyroclastic density currents in case of a stronger eruption
• Lahars (mudflows) due to heavy rains mixing with volcanic material
• Earthquakes that may trigger landslides in unstable areas

Communities around Kanlaon, particularly in Negros Occidental and Negros Oriental, are advised to stay updated on PHIVOLCS bulletins and prepare emergency evacuation plans.

Local disaster risk reduction offices have been instructed to monitor activity closely and ensure that residents are aware of emergency protocols.

History of Kanlaon’s Eruptions

Kanlaon is one of the most active volcanoes in the Philippines, with a history of eruptive activity dating back centuries. The last significant eruption occurred in 2020, when it spewed ash 1,500 meters into the sky, affecting air travel and nearby communities.

Past eruptions have been characterized by small to moderate explosions, ashfall, and occasional lava flows. However, PHIVOLCS warns that volcanic activity can escalate rapidly, making continuous monitoring crucial.

What Comes Next?

PHIVOLCS will continue to monitor Kanlaon’s seismic and volcanic activity, providing updates as needed. If activity increases, the alert level may be raised, signaling higher risks for nearby communities.

Residents and tourists are strongly advised not to enter the 4-km permanent danger zone, as unexpected explosions and gas emissions could pose serious risks. The aviation sector has also been alerted, as ash clouds from an eruption could disrupt flights in the region.

Authorities urge the public to remain vigilant and to rely only on official information from PHIVOLCS and local government units to avoid misinformation and panic.
