Negros Island, Philippines – Kanlaon Volcano, one of the most active volcanoes in the Philippines, is showing signs of increased activity, prompting authorities to raise the alert level and take precautionary measures to ensure public safety. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has been closely monitoring the situation, providing real-time updates on the volcano’s restiveness.
Current Status
As of today, PHIVOLCS has raised the alert level for Kanlaon Volcano to Level 2, indicating a state of moderate unrest. This decision follows a series of volcanic earthquakes, increased gas emissions, and observable changes in the crater’s thermal activity.
Volcanic Earthquakes
PHIVOLCS reported a significant increase in the number of volcanic earthquakes over the past 24 hours. The seismic activity is centered around the summit and lower slopes of the volcano, suggesting magma movement beneath the surface.
Gas Emissions
Measurements of sulfur dioxide (SO2) emissions have shown elevated levels, reaching an average of 500 tonnes per day. The increased gas output is indicative of rising magma and heightened volcanic activity.
Thermal Changes
Thermal cameras have detected hotspots on the crater floor, which are consistent with increased heat flow from the magma beneath. These thermal anomalies are a key indicator of potential eruptive activity.
Safety Precautions
In response to the increased activity of Kanlaon Volcano, authorities have implemented several safety measures to protect residents and visitors in the vicinity. These measures are designed to mitigate the risks associated with potential eruptions and ensure the safety and well-being of the affected communities.
Evacuation Plans
Local government units (LGUs) in affected areas have been instructed to prepare for possible evacuations. This involves coordinating with local disaster risk reduction and management offices to establish clear evacuation routes and designate safe areas for temporary shelter. The preparation includes logistical planning for transportation, food, water, and medical supplies to support evacuees.
Permanent Danger Zone (PDZ)
Residents within a 4-kilometer radius of the crater, known as the Permanent Danger Zone (PDZ), have been advised to evacuate as a precautionary measure. The PDZ is a high-risk area where the likelihood of experiencing volcanic hazards such as pyroclastic flows, lava flows, and ashfall is significantly higher.
Evacuation Procedures
Evacuation procedures involve disseminating information through various channels, including local radio, social media, and community leaders. Authorities emphasize the importance of prompt evacuation to minimize risks and ensure that residents reach safety before any potential eruption.
Air Travel Advisories
The Civil Aviation Authority of the Philippines (CAAP) has issued advisories to pilots to avoid flying near the volcano’s summit. Ash clouds from potential eruptions could pose a significant hazard to aircraft, including engine failure and reduced visibility.
Impact on Air Travel
Airlines operating in the region have been informed of the potential risks, and flight routes are being adjusted to ensure the safety of passengers and crew. The CAAP continues to monitor the situation closely and provides real-time updates to aviation authorities and airlines.
Safety Measures for Aviation
Pilots are advised to remain vigilant and report any sightings of volcanic ash to air traffic control. Additionally, airports in the region are on high alert, ready to implement contingency plans in case of significant ashfall that could affect airport operations.
Educating the Public
Local government units, in coordination with PHIVOLCS, are conducting public awareness campaigns to educate residents about the risks associated with volcanic activity. These campaigns aim to inform the public about the potential hazards of Kanlaon Volcano and the importance of following evacuation orders and safety guidelines.
Communication Channels
The campaigns utilize various communication channels to reach a broad audience, including local media, social media platforms, community meetings, and educational materials distributed in schools and public places. The goal is to ensure that everyone, including those in remote areas, receives timely and accurate information.
Importance of Preparedness
Authorities emphasize the importance of preparedness in reducing the impact of volcanic hazards. Residents are encouraged to prepare emergency kits containing essential items such as food, water, clothing, medications, and important documents. Public awareness efforts also focus on teaching residents how to protect themselves from ashfall and other volcanic hazards.
Community Involvement
Community involvement is crucial in these campaigns. Local leaders and volunteers play a vital role in spreading information, organizing evacuation drills, and assisting with the implementation of safety measures. Their active participation helps build resilience and ensures that communities are better prepared to respond to emergencies.
Historical Context
Kanlaon Volcano has a long history of eruptions, with significant events recorded as far back as the 19th century. The most recent notable eruption occurred in December 2017, which resulted in minor ashfall and the evacuation of nearby residents.
Previous Eruptions
- December 2017: A phreatic eruption sent ash plumes into the sky, affecting nearby towns with ashfall. The event prompted a temporary evacuation of residents within the PDZ.
- August 1996: A more significant eruption occurred, producing pyroclastic flows and heavy ashfall. This event caused considerable disruption to communities and agriculture in the area.
PHIVOLCS Monitoring Efforts
PHIVOLCS continues to maintain a comprehensive monitoring network around Kanlaon Volcano, utilizing seismic, geodetic, and gas monitoring equipment to track the volcano’s activity.
Seismic Monitoring
Seismic stations around Kanlaon record and analyze volcanic earthquakes, providing crucial data on magma movement and potential eruption precursors.
Gas Monitoring
SO2 monitoring instruments measure gas emissions from the crater, helping to assess the amount of magma degassing and its implications for volcanic activity.
Remote Sensing
Satellite imagery and thermal cameras provide additional insights into changes in the volcano’s surface temperature and deformation patterns.

Community Response
Communities around Kanlaon Volcano are on high alert, with many residents already preparing for possible evacuations. Local schools and community centers are being designated as temporary shelters for evacuees.
Personal Preparedness
Residents are advised to prepare emergency kits containing essential items such as food, water, clothing, medications, and important documents. It is also recommended to have a family evacuation plan in place and to stay in touch with local authorities for instructions.
Support and Assistance
Humanitarian organizations, including the Philippine Red Cross, are on standby to provide support and assistance to affected communities. These organizations play a vital role in ensuring the safety and well-being of evacuees.
Conclusion
The restiveness of Kanlaon Volcano underscores the importance of preparedness and vigilance in the face of natural hazards. As PHIVOLCS and local authorities continue to monitor the situation, the cooperation and resilience of communities will be crucial in mitigating the impact of any potential eruption.
