The Iloilo City Health Office (ICHO) has recommended the wearing of face masks following the eruption of Mt. Kanlaon in Negros Island.

In its advisory, ICHO advised the public to wear medical or surgical masks and safety googles in outdoor areas as protection against volcanic ashfall.

To ensure food safety, ICHO told the city’s residents to cover their water containers, clean or wash their fruits with running water, and thoroughly wash their hands before cooking and eating.

Kanlaon erupted on Monday, Dec. 9. According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the “explosive eruption” produced a voluminous plume.

The city government, according to Mayor Jerry Treñas, is “closely monitoring the ongoing volcanic eruption.”

“Even though the current wind direction indicates that ashfall is less likely to directly affect Iloilo City, still, safety is our top priority,” he said in a statement.

“We urge everyone to follow the guidelines and advice issued by local authorities and emergency services. Stay informed through official channels and avoid spreading misinformation,” he further said.

Based on an advisory issued by the Iloilo City Emergency Operations Center at 3 p.m. on  Tuesday, Dec. 10, the city’s air quality was categorized as “moderate.”

The moderate category means that the air quality  is “generally acceptable but may pose minor health concerns for individuals unusually sensitive to air pollution.”

“Current sulfur dioxide (SO₂) levels are measured at 3.77 mg/m², with prevailing winds moving towards west-southwestward at 10-15 kilometer per hour, reducing the likelihood of SO₂ directly affecting Iloilo City at this time,” the center said.

“Additionally, volcanic ashfall hazards remain a concern. Ashfall can cause eye irritation, respiratory issues, and skin irritation, as well as contaminate water supplies, disrupt electrical systems, and damage buildings and vehicles.”IMT
