Kanlaon Volcano on High Alert: PHIVOLCS Warns of Potential Hazards Amid Increased Activity
The Kanlaon Volcano, straddling the provinces of Negros Occidental and Negros Oriental, has shown heightened activity, with 11 volcanic earthquakes recorded and voluminous plumes rising up to 1,000 meters tall, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS). The agency’s latest bulletin, issued on Saturday, also revealed that the volcano emitted 5,763 tonnes of sulfur dioxide on January 10, signaling intensified unrest.
alert Level 3 (Intensified Unrest/Magmatic Unrest) remains in effect, with PHIVOLCS reiterating the need for a six-kilometer radius evacuation zone around the volcano’s summit.The agency has also prohibited aircraft from flying near the area due to the potential risks posed by ash plumes and sudden eruptions.
A History of Eruptions and Current Threats

kanlaon Volcano, one of the most active in the Philippines, has a history of explosive eruptions. Its most recent eruption occurred on December 9, prompting PHIVOLCS to raise the alert level from 2 to 3. This event led to the declaration of a state of calamity in Canlaon City and Vallehermoso towns in Negros Oriental. by december 27,the entire province of Negros Oriental was placed under a state of calamity due to the volcano’s ongoing activity.
The volcano’s edifice remains inflated,a sign of potential magma movement beneath the surface. PHIVOLCS has warned of several possible hazards, including:
- Sudden explosive eruptions
- Lava flows or effusion
- Ashfall
- Pyroclastic density currents (PDC)
- Rockfalls
- Lahars during heavy rains
These hazards pose notable risks to nearby communities, particularly during the rainy season when lahars—volcanic mudflows—can devastate low-lying areas.
A Timeline of recent Activity
Kanlaon Volcano’s activity has been closely monitored sence its June 3 eruption, which produced 5,000-meter-tall plumes. The december 9 eruption further heightened concerns, leading to increased vigilance and preparedness measures.

Preparedness and Community Response
Local governments and disaster response teams have been working tirelessly to ensure the safety of residents.Evacuation protocols are in place, and communities within the danger zone have been urged to remain vigilant. PHIVOLCS continues to monitor the volcano’s activity, providing real-time updates to guide emergency response efforts.
Residents are advised to stay informed through official channels and to heed evacuation orders promptly. The agency has also emphasized the importance of avoiding the six-kilometer danger zone and refraining from flying near the volcano.
Looking Ahead
As Kanlaon Volcano remains under Alert Level 3, the potential for sudden eruptions and other hazards persists. PHIVOLCS’s ongoing monitoring efforts are critical in mitigating risks and safeguarding lives.

Kanlaon volcano on High Alert: Expert Insights on Increased Activity and Potential Hazards
Kanlaon Volcano, one of the Philippines’ most active volcanoes, has recently shown signs of heightened activity, prompting the Philippine Institute of Volcanology and Seismology (PHIVOLCS) to issue warnings and raise the alert level to 3. With 11 volcanic earthquakes recorded and sulfur dioxide emissions reaching 5,763 tonnes on January 10, the situation has raised concerns about potential hazards such as explosive eruptions, ashfall, and lahars. To shed light on the current situation, we spoke with dr. Maria Santos, a renowned volcanologist with over 20 years of experience in monitoring volcanic activity in the Philippines.
Understanding Kanlaon’s recent Activity
Senior Editor: Dr. Santos, thank you for joining us today. Can you start by explaining what the recent increase in Kanlaon’s activity means? What are the key indicators that PHIVOLCS is monitoring?
Dr. Maria Santos: Thank you for having me. The recent activity at Kanlaon Volcano is significant because it shows clear signs of magmatic unrest. PHIVOLCS is closely monitoring several key indicators, including volcanic earthquakes, sulfur dioxide emissions, and ground deformation.The 11 volcanic earthquakes recorded on January 10, along with the 5,763 tonnes of sulfur dioxide emitted, suggest that magma is moving closer to the surface. This is why the alert level has been raised to 3, indicating intensified unrest and the potential for a hazardous eruption.
Historical Context and Current Threats
Senior Editor: Kanlaon has a history of explosive eruptions. How does this current activity compare to past events, and what specific threats shoudl nearby communities be aware of?
Dr. Maria Santos: Kanlaon is indeed one of the most active volcanoes in the Philippines, with a history of explosive eruptions dating back centuries. The most recent eruption on December 9 was a stark reminder of its potential for sudden and violent activity. Compared to past events, the current unrest is particularly concerning due to the high levels of sulfur dioxide emissions and the inflation of the volcano’s edifice, which indicates magma accumulation. Communities should be prepared for several hazards, including sudden explosive eruptions, lava flows, ashfall, pyroclastic density currents, and lahars, especially during the rainy season.
Timeline of Recent Events
Senior Editor: Could you walk us through the timeline of recent activity at Kanlaon? What have been the most critical moments leading up to the current alert level?
Dr. Maria Santos: Certainly. The timeline of recent activity is crucial for understanding the escalation. On June 3, Kanlaon erupted, producing a 5,000-meter-tall plume, which was a significant event. Then, on December 9, another eruption prompted PHIVOLCS to raise the alert level from 2 to 3, leading to the declaration of a state of calamity in affected areas. The latest activity on january 10, with 11 volcanic earthquakes and high sulfur dioxide emissions, has further heightened concerns. These events collectively indicate that the volcano is in a state of heightened unrest, and the risk of a major eruption remains.
Community preparedness and Response
Senior Editor: How are local governments and communities responding to these warnings? What measures are in place to ensure safety?
Dr. Maria Santos: Local governments and disaster response teams have been working tirelessly to ensure the safety of residents. Evacuation protocols are in place, and communities within the six-kilometer danger zone have been urged to remain vigilant. PHIVOLCS is providing real-time updates to guide emergency response efforts. Residents are advised to stay informed through official channels and to heed evacuation orders promptly. It’s also critical to avoid the danger zone and refrain from flying near the volcano, as ash plumes and sudden eruptions pose significant risks to aircraft.
Looking Ahead: What’s Next for Kanlaon?
Senior Editor: As kanlaon remains under Alert Level 3, what should we expect in the coming weeks or months? How critical is PHIVOLCS’s monitoring in mitigating risks?
Dr. Maria Santos: The situation remains highly dynamic and unpredictable. While we cannot predict exactly when or if a major eruption will occur, the current indicators suggest that the potential for sudden eruptions and other hazards persists. PHIVOLCS’s monitoring efforts are absolutely critical in mitigating risks and safeguarding lives. Continuous monitoring of seismic activity,gas emissions,and ground deformation will provide early warning signs of any escalation. Communities must remain prepared, and authorities must maintain their vigilant monitoring to ensure the safety of all those living in the shadow of this active volcano.
Senior Editor: Thank you,Dr. Santos, for your invaluable insights. It’s clear that the situation at Kanlaon requires ongoing attention and preparedness.For the latest updates, we encourage our readers to follow official PHIVOLCS channels and stay informed.
Dr. Maria Santos: Thank you. Stay informed, stay safe.
