The Philippine Institute of Volcanology and Seismology (Phivolcs) reported another phreatic or steam-driven eruption at Taal Volcano at around 12:39 p.m. on Thursday, Sept. 26.
Based on records from the Taal Volcano Observatory located in Brgy. Buco, Talisay, Batangas, the eruption generated a plume that rose approximately 2,400 meters above Taal Volcano Island.
On Wednesday, Sept. 25, Phivolcs said Taal Volcano also had a four-minute-long minor phreatic eruption.
Over the past 24 hours, two volcanic tremors that lasted three to nine minutes were detected at the active volcano in Batangas.
Sulfur dioxide (SO2) emissions reached 3,176 tons, while an upwelling of hot volcanic fluids in the Main Crater Lake continues to be observed.
Phivolcs reiterated that Alert Level 1 (low-level unrest) remains in effect for Taal Volcano, indicating abnormal conditions.
This alert level signifies the risks of sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and hazardous volcanic gas emissions, especially on Taal Volcano Island (TVI).
Phivolcs advised the public to avoid entering the TVI, particularly near the Main Crater and Daang Kastila fissure, which are considered permanent danger zones.
Local government units are also advised to monitor SO2 levels, assess their effects, and implement measures to mitigate these hazards.
