The Philippine Institute of Volcanology and Seismology (PHILVOLCS) reported that Kanlaon Volcano emitted ash in four separate events on Monday, lasting up to four hours and 35 minutes.

In a bulletin released Tuesday morning, PHIVOLCS stated that the ash plumes rose to approximately 1,500 meters above the summit and drifted westward. The emissions were accompanied by weak volcanic earthquakes, consistent with the ongoing low-level unrest.

Kanlaon Volcano, situated in Negros Island, remains under Alert Level 1, indicating "abnormal" activity. 

PHIVOLCS clarified while there is no imminent threat of a major eruption at the moment, residents should be prepared for potential hazards, including ashfall, pyroclastic flows, and localized earthquakes.

Advisory for Communities

The agency strongly advised local governments and communities within the four-kilometer Permanent Danger Zone (PDZ) to prohibit entry due to the possibility of sudden steam-driven or phreatic eruptions.

Those living near the volcano are also urged to monitor updates and ensure access to emergency supplies.

Ashfall from the recent emissions was reported in parts of La Castellana and San Carlos City, Negros Occidental.

Residents in affected areas are reminded to wear protective masks and cover water sources to minimize health risks.

Government Preparedness

Local disaster risk reduction and management offices have been placed on alert, ensuring evacuation plans and emergency response systems are ready if the situation escalates.

Relief agencies have also been mobilized to provide assistance in case of displacement caused by ashfall or other volcanic hazards.

The Civil Aviation Authority of the Philippines (CAAP) has issued a notice to pilots to avoid flying near the summit due to the potential risk of volcanic ash, which could damage aircraft engines and reduce visibility.

Volcanic Activity Monitoring

The agency continues to closely monitor Kanlaon Volcano’s seismic activity, gas emissions, and ground deformation. 

Authorities have deployed additional equipment to ensure accurate monitoring of the volcano’s behavior.

In 2016, Kanlaon experienced a phreatic eruption that disrupted local flights and blanketed nearby towns with ash.

PHIVOLCS reiterated that any changes in activity could lead to a higher alert level.

For now, residents are encouraged to remain vigilant and heed official warnings. Further information will be provided through subsequent bulletins and updates from PHIVOLCS.
