Kanlaon Volcano records 72 earthquakes in 8-hour period

The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded 72 volcanic earthquakes at Kanlaon Volcano between midnight and 8 AM on Monday, September 15, 2025, a significant increase.

These earthquakes, ranging from magnitude 0.8 to 3.6, are attributed to magma and volcanic gases moving upward, causing pressure buildup within the volcano.

Sulfur dioxide emissions on Sunday, September 14, 2025, reached 2,338 tonnes per day, with plumes rising 900 meters.

Phivolcs warned that the volcano's current activity may trigger hazards such as steam-driven explosions, ashfall, rockfall, and pyroclastic flows.

Kanlaon Volcano remains under Alert Level 2, indicating increased unrest, and entry into its four-kilometer permanent danger zone is prohibited.

Flights near the summit are banned, and the volcano's edifice remains inflated.
