The Philippine Institute of Volcanology and Seismology (Phivolcs) reported a weak ash emission from the summit crater of Kanlaon Volcano on Monday afternoon, Sept. 8.

According to Phivolcs, the ash emission began at 5:25 p.m. and produced a low plume drifting west-southwest.

The activity ceased at 6:20 p.m.

Despite the event, Alert Level 2 remains in effect over Kanlaon Volcano, indicating unrest.

However, Phivolcs emphasized that the current level does not rule out the possibility of sudden explosions or a return to heightened activity.

Sulfur dioxide emissions were measured at 1,171 tons per day on Sept. 7.

Phivolcs reiterated that communities within the four-kilometer permanent danger zone should remain evacuated due to the ongoing threat of sudden explosive events, pyroclastic density currents, rockfalls, and the release of volcanic gases.

Local government units are advised to stay prepared for potential evacuation orders should volcanic activity intensify.

Meanwhile, civil aviation authorities were reminded to avoid flying near the summit due to the continued risk posed by unexpected ash emissions.

Phivolcs also warned of possible lahars and sediment-laden streamflows in the event of heavy rainfall around the volcano.
