Ongoing Earthquakes and Tremors Shake Taal Volcano
LUCENA CITY — Taal Volcano in Batangas province continues to experience volcanic earthquakes and tremors, officials reported early Monday morning, Sept. 1. The persistent seismic activity has kept local authorities and residents alert as the volcano remains under close observation.
According to sources, Taal Volcano recorded 11 volcanic earthquakes in the past 24 hours, alongside a continuous volcanic tremor event that has been ongoing since Aug. 27. These developments highlight the volcano’s active state and the importance of monitoring its behavior closely.
Understanding Volcanic Earthquakes and Tremors
Experts explained that volcanic earthquakes are seismic events generated by magmatic or magma-related processes beneath or near an active volcano. Just the day before, five such earthquakes were logged, emphasizing the volcano’s restless condition.
Meanwhile, volcanic tremors consist of continuous seismic signals characterized by a sine wave pattern and low frequencies ranging from 0.5 to 5 Hz. These tremors may result from various internal volcanic processes, including the resonance of magma flowing through cracks and vents, or from closely occurring low-frequency quakes and explosions.
Significant Sulfur Dioxide Emissions Recorded
Aside from seismic activity, the volcano emitted 4,514 metric tons of sulfur dioxide, producing plumes that rose as high as 1,500 meters. Authorities classified this as a “voluminous emission,” signaling notable volcanic gas release during the monitoring period.
Despite these emissions, no upwelling of hot volcanic fluids was observed in the Main Crater Lake. Additionally, volcanic smog, commonly known as “vog,” was not detected at the time of observation.
Current Alert Level and Safety Precautions
Officials reiterated that Taal Volcano remains at Alert Level 1, indicating it is in an abnormal condition. This status warns that unrest has not ceased and that eruptive activity could still occur. At this alert level, sudden steam-driven or phreatic eruptions, minor ashfall, volcanic earthquakes, and dangerous gas expulsions may happen, especially within Taal Volcano Island (TVI).
Consequently, entry to the island, boating on Taal Lake, and flying aircraft near the volcano continue to be strictly prohibited to ensure public safety.
Community Vigilance and Ongoing Monitoring
Local leaders and community members remain vigilant as monitoring efforts intensify. They emphasize the importance of abiding by safety regulations and staying informed through official channels.
