Kanlaon Volcano Eruption Update: Concerns Over Ash Plume and Ongoing Alert Level 3

MANILA – A significant volcanic event was recorded at Kanlaon Volcano in the Philippines on Monday. According to the Philippine Institute of Volcanology and Seismology (Phivolcs), a dark plume of ash approximately 1.2 kilometers high was observed emanating from the volcano’s summit at 11:45 a.m.

Ash Emission and Associated Earthquake

The ash emission was accompanied by a low-frequency volcanic earthquake, a common precursor to such volcanic activities. This latest development underscores the current state of magmatic unrest at Kanlaon Volcano.

Expected Ashfall and Community Impact

Phivolcs issued a warning regarding the potential for ashfall in communities located northwest to west of the volcano. Specifically, Negros Occidental may experience ash accumulation, necessitating the attention and careful planning from local authorities.

Continued Monitoring and Alert Level 3

Kanlaon Volcano has been under Alert Level 3, an indication of heightened magmatic unrest, since December 9. This status suggests an increased likelihood of sudden, stronger explosive eruptions that could pose significant life-threatening hazards to nearby communities.

According to Phivolcs, while other volcanic activities remain elevated, they have not shown substantial changes. The institution will continue to monitor the situation closely for any further developments.

Additional Hazards and Precautions

Phivolcs also emphasized the potential for heavy rainfall to trigger lahars—mudflows—along with sediment-laden streamflow in the southern flanks of the volcano. Specific areas at risk include La Castellana and certain barangays in Canlaon City, which have historically been impacted by previous lahar events, particularly in June 2024.

Aviation Safety Advisories

In light of these developments, Phivolcs has advised aviation authorities to direct pilots to avoid flying near the volcano’s summit. Ash clouds from a sudden eruption could pose considerable danger to aircraft.

Conclusion

The latest volcanic activity at Kanlaon Volcano highlights the importance of public awareness and adherence to safety guidelines. Local communities are encouraged to stay informed through Phivolcs updates and remain vigilant for further warnings.

Phivolcs will continue to monitor the volcano closely to provide timely updates and ensure the safety of all residents and visitors in the vicinity.
