LUCENA CITY — Taal Volcano in Batangas province recorded another minor phreatic eruption and four earthquakes on Friday, Nov. 29, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported.
“A minor phreatic eruption from Taal Volcano Island’s Main Crater at 11:25 AM today (29 November 2024), which generated a 1,200-meter white plume, was captured by the IP camera of the Agoncillo Observation Station,” Phivolcs said in a post on its Facebook page.

A phreatic eruption occurs when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits (for example, tephra and pyroclastic-flow deposits), Phivolcs explained.

Volcanic tremors, on the other hand, are “continuous seismic signals with regular or irregular oscillations and low frequencies (typically 0.5–5 Hz) that can last for more than a minute.”

Phivolcs classified the volcano’s latest spewing activity as “voluminous emission.”
However, there was no reported upwelling of hot volcanic fluids in the Main Crater Lake on Taal Volcano Island.
No volcanic smog, or “vog,” was also observed during the latest monitoring period.
Taal Volcano is still under alert level 1 (low level of volcanic unrest), Phivolcs said.
