The Philippine Institute of Volcanology and Seismology (PHIVOLCS) confirmed that Kanlaon Volcano on Negros Island remains under Alert Level 2, following a noticeable increase in volcanic activity over the past 24 hours.
In its latest bulletin released October 21, 2025, PHIVOLCS said the current alert level indicates moderate unrest driven by shallow magmatic or hydrothermal processes that could lead to steam-driven or minor magmatic eruptions.
From 12 a.m. Monday to 12 a.m. Tuesday, the volcano recorded seven ash emissions lasting between 1 and 123 minutes, along with 20 volcanic earthquakes—signs of continued movement beneath the surface.
PHIVOLCS also reported elevated sulfur dioxide (SO₂) emissions averaging 3,194 tons per day as of October 20. The volcano’s steam and ash plume rose about 450 meters high, drifting toward the west and northwest.
Ground deformation data further revealed that the volcano continues to swell, suggesting magma accumulation beneath Kanlaon’s edifice.
Authorities continue to enforce a no-entry policy within the 4-kilometer Permanent Danger Zone (PDZ) and strongly advise against flying aircraft near the summit due to possible ash and debris hazards.
“Kanlaon remains under Alert Level 2, which means the volcano is restless. Sudden steam-driven or phreatic eruptions may still occur without warning,” PHIVOLCS reminded the public.
Local governments and residents in Negros Occidental and Negros Oriental are urged to remain vigilant and to coordinate with authorities for any updates.
Kanlaon Volcano, straddling the boundary between the two Negros provinces, is one of the most active volcanoes in the Philippines, with its last significant eruption recorded in 2024.
