BACOLOD CITY – The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported 16 volcanic earthquakes at Kanlaon Volcano since Saturday midnight, signaling increased activity in the region.
PHIVOLCS noted that Kanlaon emitted 4,992 tonnes of sulfur dioxide on Saturday, accompanied by a “voluminous” 500-meter tall plume drifting southward.
The volcano’s edifice remains inflated, prompting authorities to maintain Alert Level 2 due to “increased unrest” following its June 3 explosive eruption.
Local authorities are coordinating with PHIVOLCS to implement evacuation plans if the alert level increases. Residents are advised to stay informed through official channels and follow safety guidelines.
PHIVOLCS has prohibited entry within the volcano’s 4-kilometer radius permanent danger zone and restricted aircraft flights near the area due to the risk of sudden steam-driven or phreatic eruptions.
Last week, sulfur odor affected five local government units in Negros Occidental, leading to the cancellation of face-to-face classes in schools near the volcano’s base.
In response, Negros Occidental Gov. Eugenio Jose Lacson said the provincial government could provide face masks to affected residents.
“We are always wary of an eruption. Whatever instructions are issued, especially by the disaster risk reduction office, just follow them,” Lacson said.
“It is unfortunate that the wind is not in our favor. The sulfur dioxide has always been there, but in the past, the wind blew it away. Now, it’s blowing toward us, and that’s why people can smell it,” he added.
The Provincial Disaster Management Program Division, encouraged residents to wear face masks for protection against hazardous fumes.
Kanlaon Volcano, standing at 2,435 meters (7,989 feet), is one of the most active volcanoes in the Philippines. Its last major eruption occurred in 1969, but it has shown intermittent activity in recent years.
