An ash plume rose from Kanlaon Volcano early Thursday morning, May 28 as the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported an ongoing ash emission event that began at 6 a.m.

Phivolcs said the activity generated grayish ash plumes rising about 1,200 meters above the summit crater before drifting southwest, based on images captured by the IP camera at the Kanlaon Volcano Observatory in Canlaon City.

The agency also recorded 18 volcanic earthquakes over the past 24 hours, including one volcanic tremor that lasted four minutes.

Kanlaon Volcano remains under Alert Level 2, or moderate level of unrest, a status that has been in effect since July 29, 2025.

Phivolcs said Alert Level 2 signifies increased unrest and the possibility of sudden explosive eruptions.

The agency reiterated that entry into the volcano’s four-kilometer permanent danger zone remains strictly prohibited due to hazards such as ashfall, ballistic fragments, pyroclastic density currents, and volcanic gases.

Communities near rivers and streams draining the volcano were also advised to remain vigilant, particularly during heavy rainfall, due to the risk of lahars.

Phivolcs also warned civil aviation authorities against flying close to the volcano’s summit because of possible ash emissions.
