Kanlaon Volcano Sends Ash Plume 500 Meters Above Summit In Philippines

Kanlaon Volcano sent a grayish ash plume 500 meters above its summit crater at 6:02 p.m. on Sept. 9, with the emission drifting northeast.

Sped-up footage from the Canlaon City Observation Station shows a dark burst of ash pushing through the summit cloud before rising and expanding into a thick plume. The column then sheared toward the northeast and spread across the ridge.

The plume gradually thinned as the summit became obscured by cloud and residual ash. No lava or pyroclastic density current was visible in the footage.

Kanlaon Volcano, which stands 2,422 meters high on Negros Island, remains under Alert Level 2, indicating increased unrest. The volcano has been in an ongoing eruptive period since June 3, 2024.

The Sept. 9 event was classified as an ash emission. A 24-hour summary dated Sept. 7 recorded 11 volcanic earthquakes, sulfur dioxide emissions of about 1,094 tons per day and a 150-meter steam plume.

Entry into the 4-kilometer Permanent Danger Zone remains prohibited.
