Phivolcs Reports Minor Phreatic Eruption at Taal Volcano

Fortunato Guevarra

The Philippine Institute of Volcanology and Seismology (Phivolcs) reported a minor phreatic eruption at Taal Volcano on Thursday afternoon. The event occurred between 4:33 p.m. and 4:35 p.m., as confirmed by the Main Crater Thermal and IP Camera of the state seismology agency.

This eruption produced white steam plumes rising approximately 300 meters above the volcano’s crater. Despite the activity, Taal Volcano remains under Alert Level 1, indicating a low level of volcanic unrest.

Phivolcs describes phreatic eruptions as steam-driven explosions triggered when magma, lava, hot rocks, or new volcanic deposits heat water located beneath the surface or on the ground. Continuous monitoring efforts remain in place to observe any changes in the volcano’s behavior.
