The Philippine Institute of Volcanology and Seismology (Phivolcs) on Sunday, Nov. 23, reported a brief phreatomagmatic eruption at the Main Crater of Taal Volcano, which produced a grayish plume that rose around 750 meters.
Phivolcs said the activity occurred from 9:48 a.m. to 9:50 a.m., based on time-lapse footage captured by the Daang Kastila (VTDK) thermal camera.
The plume drifted southwest after the eruption.
A phreatomagmatic eruption happens when magma interacts with water, generating steam, ash, and occasionally fragmented volcanic materials.
Alert Level 1 remains raised over Taal, indicating abnormal activity but no imminent eruption.
However, Phivolcs warned that sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and hazardous accumulations of volcanic gases may still occur in the main crater area.
The agency advised the public not to enter Taal Volcano Island, particularly the main crater and the Daang Kastila fissure, due to the risk of sudden dangerous events.
Communities around Taal Lake were also urged to stay vigilant.
