Rising Seismic Activity Triggers Taal Volcano Early Warning
The Philippine Institute of Volcanology and Seismology (Phivolcs) has issued an urgent early warning regarding the Taal Volcano in Batangas. Officials reported a notable increase in seismic activity, signaling a potential minor eruption in the coming days.
Phivolcs emphasized that the early warning is based on data from the Taal Volcano Network (TVN), which recorded a surge in real-time seismic energy measurement (RSAM) starting Sunday morning. Community members noted that 19 volcanic earthquakes have occurred since the previous day, indicating heightened unrest beneath the volcano.
Volcanic Tremors and Plume Observations Raise Concerns
Alongside the seismic readings, state seismologists observed a “moderate to voluminous plume” rising from Taal’s main crater coinciding with the RSAM increase. Officials reported that since June, the volcano has consistently emitted low levels of sulfur dioxide, with an average release of 412 tons recorded last Friday alone.
These developments have led experts to warn that the sharp rise in RSAM combined with vigorous steaming could trigger phreatic or minor phreatomagmatic eruptions. Local leaders stressed that these types of eruptions can occur suddenly and may pose risks to nearby communities.
Alert Level 1 Remains as Authorities Urge Caution
Phivolcs reiterated that Taal Volcano remains under Alert Level 1, indicating low-level unrest. Officials urged residents and visitors to remain vigilant, as sudden steam-driven or minor eruptions, ashfall, gas expulsions, and other volcanic hazards remain possible.
The agency strongly prohibits entry into the Taal Volcano Island and the permanent danger zone, especially around the main crater and Daang Kastila. Aviation authorities also advise against flying over the area due to the threat of volcanic ash impacting aircraft safety.
Community Preparedness and Safety Measures
Local authorities and community members are being urged to stay informed and prepared for any sudden changes in volcanic activity. Evacuation plans and monitoring systems remain in place to ensure quick response should the situation escalate.
Experts continue to monitor Taal closely, emphasizing that the volcano’s abnormal condition has not subsided. They caution the public against assuming the unrest has ended or that the threat of eruption is over.
