Current Advisory Alert for the Kanlaon Volcano: October 28, 2024

Overview of the Kanlaon Volcano Activity

On October 28, 2024, the Kanlaon Volcano, situated in the central Philippines, is under heightened observation due to significant geological activity. Recent measurements indicate a marked increase in volcanic sulfur dioxide (SO₂) emissions, reaching an alarming rate of 10,074 tonnes per day. This substantial release of SO₂ gas could signal potential volcanic unrest, warranting immediate attention and caution from local authorities and residents.

The Importance of Monitoring Sulfur Dioxide Emissions

Sulfur dioxide emissions play a crucial role in assessing volcanic activity. Elevated levels of SO₂ are often considered a precursor to eruption, as they reflect the movement of magma closer to the Earth's surface. The 10,074 tonnes per day observed at Kanlaon can indicate both physical changes within the volcano and potential hazards that may affect surrounding areas. Monitoring these emissions not only supports scientific research but also aids in developing strategies for public safety and hazard mitigation.

Recommendations for Residents and Local Authorities

In light of the recent advisory alert concerning the Kanlaon volcano, it is imperative for residents living in proximity to the volcano to stay informed about the current situation. Local authorities should enhance monitoring efforts and communicate effectively with the community regarding safety protocols. Regular updates from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) will be essential in guiding residents on precautions they must take during this period of increased activity.

Finally, it is recommended that residents prepare an emergency plan, which includes provisions for evacuation, essential supplies, and a communication strategy with family members. Given the potential dangers of increased volcanic activity, the well-being and safety of the community must remain a priority as conditions continue to evolve.

Health Precautions
Prolonged exposure to SO₂ can irritate the eyes, throat, and respiratory system, particularly affecting sensitive groups, including individuals with asthma, lung or heart disease, the elderly, pregnant women, and children. Those in affected areas should take the following precautions:

1. Limit Outdoor Activities: Stay indoors, close doors and windows to minimize exposure.

2. Protective Measures: Use an N95 mask, and drink water to alleviate throat irritation. Those with preexisting health conditions should monitor their health closely and seek medical help if necessary.

Volcano Alert Level and Safety Measures
Kanlaon remains at Alert Level 2, signaling increasing unrest with potential for eruption. The public is advised to avoid the four-kilometer-radius Permanent Danger Zone (PDZ) due to risks from pyroclastic flows, ballistic fragments, and other hazards. In case of ashfall, use a clean cloth or mask to cover the nose and mouth. Additionally, civil aviation authorities are advised to restrict flights near the summit to avoid volcanic ash and debris.

Communities near river systems on Kanlaon’s slopes, particularly those that have experienced lahar flows, should be cautious during heavy rain due to possible streamflows carrying volcanic material.

The Department of Science and Technology - Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) is closely monitoring Kanlaon and will issue further updates as needed.
