Volcanic activity at Canlaon volcano continues at low levels and has not shown significant variations recently. According to the recent bulletins released by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the Canlaon volcano monitoring network has detected eleven (11) volcanic earthquakes during the last 7 days. Moderate emissions of steam-laden plumes were observed to rise 300m before drifting northwest. Sulfur dioxide (SO2) emissions were recorded at 96 tonnes/day last 8 May 2021. The lower and middle slopes of the volcano have been observed to be slightly inflating since June 2020 based on continuous GPS and electronic tilt measurements. This may indicate hydrothermal, tectonic, or deep-seated magmatic processes ongoing underneath the surface.

PHIVOLCS maintains the Alert Level 1 at Canlaon volcano. This means that it is at an abnormal condition and showing signs of unrest. There is a possibility of sudden phreatic eruptions so entry into the 4-kilometer permanent danger zone is strictly prohibited.
