A phreatic eruption occurred at the summit crater of Taal Volcano on Thursday, 11th September, around 4:33 p.m., as reported by the Philippine Institute of Volcanology and Seismology (Phivolcs). The event sent steam-laden plumes soaring approximately 300 metres into the sky, highlighting a potential threat amid the volcano's ongoing low-level unrest classified under Alert Level 1.

 

Phreatic eruptions, caused by the interaction of water with hot volcanic materials like rocks or gases, can happen suddenly. Over the past 24 hours, Phivolcs recorded nine volcanic earthquakes, including six tremor events. Notably, one continuous tremor began at 6:53 a.m. on 10th September and continues at the time of reporting.

 

Additionally, sulfur dioxide emissions measured at 1,749 tons per day on 9th September signal continued activity from the crater. However, Alert Level 1 remains applicable, indicating abnormal conditions without an imminent major eruption.

 

Phivolcs cautions that sudden phreatic explosions, earthquakes, minor ashfall, and hazardous gas accumulations are possible in the area. As such, the public is strongly advised against entering Taal Volcano Island, particularly avoiding the Main Crater and Daang Kastila fissure due to the risk of hazardous events.

 

Residents in communities surrounding the lake are urged to stay vigilant, heeding advice and directives from local authorities and emergency services. Preparedness measures are crucial to ensuring safety, as volcanic activity can swiftly evolve.

 

Taal Volcano, located in the province of Batangas, is one of the Philippines' most volatile and closely monitored sites. Its latest activity reminds residents of past eruptions, reaffirming the importance of constant monitoring and readiness for potential natural hazards. The memory of Taal's January 2020 eruption, which displaced thousands and caused significant disruption, remains vivid, underscoring the need for continued caution.

 

Tourists and locals are reminded to respect evacuation zones and adhere to all safety protocols established by authorities. While the main eruption event did not lead to significant immediate damage, the possibility of sudden changes in volcanic activity means that precautionary measures must remain in place.

 

As the authorities continue to keep a close eye on developments, the public is encouraged to maintain a level of preparedness. This includes having emergency kits ready, understanding evacuation routes, and staying updated through official announcements.

 

While the current alert does not suggest an immediate catastrophic event, the dynamic nature of Taal Volcano means readiness is a necessity. Residents and tourists alike must balance their curiosity with caution, ensuring safety remains the priority.

 

The focus now is on real-time monitoring and rapid communication between authorities and the public to manage any developments effectively. With continued vigilance and cooperation, risks can be minimised. As the authorities monitor the situation, the emphasis remains on safety and preparedness to protect lives and communities around Taal.
