The Philippine Institute of Volcanology and Seismology (PHIVOLCS) continues to monitor Taal, Mayon, and Bulusan volcanoes, all under Alert Level 1 due to persistent but moderate activity. While no significant volcanic earthquakes have been reported at Taal and Mayon, Bulusan registered two minor tremors. The agency reminds the public to remain cautious as the three volcanoes exhibit varied signs of unrest.
Taal Volcano Emissions and Ground Deformation
Taal Volcano, situated in Batangas, continues to emit substantial sulfur dioxide (SO2), recorded at 2,039 tons per day on November 8. The thick steam plume from Taal reaches up to 1,500 meters, drifting southwestward. Ground deformation observations reveal long-term deflation of the Taal Caldera, though short-term inflation has been noted in the northern and southeastern sections of Taal Volcano Island. PHIVOLCS advises caution around the volcano, as emissions indicate ongoing volcanic activity, even without detected earthquakes.
Mayon’s Persistent Crater Glow
Mayon Volcano in Albay, known for its iconic shape, remains relatively calm, with no volcanic earthquakes recorded in the last 24 hours. However, PHIVOLCS observed a faint crater glow visible only through telescopes, a sign of minimal magma movement beneath the surface. SO2 emissions were measured at 746 tons per day on November 6. A moderate steam plume has been drifting towards the south-southwest. Ground deformation monitoring shows slight inflation, signaling potential minor activity. Residents are urged to remain vigilant as the volcano remains under Alert Level 1.
Bulusan’s Minor Tremors and Ground Swelling
Bulusan Volcano in Sorsogon registered two minor volcanic earthquakes and displays continuous ground swelling, indicating internal activity. SO2 emissions at Bulusan were relatively low, with 21 tons recorded per day on November 8. Clouds obscure the volcano, limiting visual observations of its plume. The ongoing ground deformation suggests magma movement within the volcano, warranting careful monitoring. PHIVOLCS warns nearby residents to stay alert and heed any advisories.
Continued Monitoring
With all three volcanoes on Alert Level 1, PHIVOLCS encourages the public, especially those near these areas, to stay alert and updated through official advisories. The agency continues to monitor volcanic activity to provide timely updates.
