Quick Read
- Mount Kanlaon erupted on Thursday, February 26, 2026, at 7:04 p.m. local time.
- The eruption sent an ash plume approximately 2,500 meters (1.5 miles) or 6,500 feet into the sky.
- Ashfall was reported in nearby communities, prompting the distribution of facemasks.
- PHIVOLCS-DOST maintains Alert Level 2, prohibiting entry into the 4-kilometer Permanent Danger Zone.
- Officials warn of a potential for a larger explosive eruption due to suspected gas pressure build-up.
NEGROS ISLAND (Azat TV) – Mount Kanlaon, one of the most active volcanoes in the Philippines, erupted on Thursday evening, February 26, 2026, sending a towering plume of ash approximately 2,500 meters (1.5 miles) into the night sky. The two-minute eruption, which began at 7:04 p.m. local time, has prompted warnings from authorities about the potential for a larger explosive event in the coming days, signaling a heightened state of vigilance for residents in the central Philippines.
Mount Kanlaon Eruption Details and Immediate Impact
The dramatic eruption was characterized by a massive dark grey smoke cloud that rose over 6,500 feet above the crater before drifting southwest, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS-DOST). Observers reported incandescent ballistics raining around the crater, while pyroclastic density currents—hot, fast-moving mixtures of volcanic particles and gas—descended the southern and southeastern upper slopes of the mountain, within half a mile of the summit crater. The event caused immediate concern in nearby communities, with John De Asis, a rescuer in La Castellana, confirming that ashfall had begun to descend on local neighborhoods. Rescue personnel were swiftly deployed to distribute facemasks to residents as a precautionary measure against the volcanic ash.
Official Response to Kanlaon Activity
PHIVOLCS-DOST Director Teresito Bacolcol indicated that the eruption was the second moderate event in a week, following an explosive eruption on February 19. Bacolcol stated in a phone interview that his agency would maintain 24-hour monitoring of Mount Kanlaon before deciding whether to raise the alert level from two to three on its five-point scale. The current Alert Level 2 signifies moderate unrest, with a four-kilometer (2.5-mile) radius Permanent Danger Zone (PDZ) strictly prohibiting entry. Authorities are particularly concerned about potential gas pressure build-up at the volcano’s vent, noting that recent low sulfur dioxide emissions could suggest a blockage, leading to increased pressure and the possibility of a more powerful eruption.
Historical Context of Kanlaon Volcano
Mount Kanlaon, also known as Kanlaon Volcano, is an andesitic stratovolcano and the highest mountain on Negros Island, straddling the Negros Oriental and Occidental provinces. It is one of 24 active volcanoes in the Philippines, an archipelago nation situated on the seismically active Pacific “Ring of Fire,” home to more than half of the world’s volcanoes. The volcano has a history of significant activity, having erupted 40 times since 1819, typically producing small to moderate ashfalls. Notably, a 1996 blast tragically killed three hikers who were near the summit. The most powerful volcanic explosion in the Philippines in recent years was the 1991 eruption of Mount Pinatubo, located about 100 kilometers (62 miles) from Manila, which claimed more than 800 lives.
The latest eruption of Mount Kanlaon, coupled with warnings of potentially larger events and the immediate impact of ashfall, underscores the persistent seismic risks faced by communities in the Philippines. The continuous monitoring and rapid response by PHIVOLCS-DOST are critical in mitigating the dangers posed by the nation’s active volcanic landscape.
