Increased seismic activity at Kanlaon Volcano has been recorded based on an advisory of the Philippine Institute of Volcanology and Seismology (PHIVOLCS) issued at 10:30 a.m. on Thursday, October 31, 2024. 

“A total of sixty-four (64) volcano-tectonic or VT earthquakes have been recorded by the Kanlaon Volcano Network since 12:00 a.m. of 31 October 2024,” the advisory reads. 

Volcanic sulfur dioxide (SO2) gas emission from the summit crater of Kanlaon on October 30, 2024 averaged 7,087 tons a day.

Kanlaon has been degassing increased concentrations of volcanic SO2 in 2024 at an average rate of 1,273 tons per day prior to a phreatic eruption on June 3, 2024 eruption, but emission since then has been particularly elevated at a current average of 4,234 tons a day.

The public is reminded that Alert Level 2 (increasing unrest) prevails over Kanlaon, but that current seismic activity may lead to eruptive unrest and an increase in the Alert Level.
