Taal Volcano, located in Batangas province in the Philippines, has been experiencing heightened seismic activity, particularly in the emission of sulphur dioxide (SO2), according to the Philippine Institute of Volcanology and Seismology (Phivolcs). On February 29, the main crater of the volcano emitted a total of 14,558 tons/day of volcanic SO2 gas, marking the second-highest recorded flux this year.
Phivolcs director Teresito “Toto” Bacolcol emphasized that Taal Volcano has been consistently degassing significant amounts of SO2 since 2021, with an average of approximately 9,450 tons/day in February. However, due to moderate winds, the accumulation of SO2 has been prevented, and no volcanic smog or vog was observed by visual monitors throughout the day. Additionally, the level of volcanic earthquake activity has remained within baseline levels.
Despite currently being under Alert Level 1, Bacolcol cautioned that Taal Volcano is still in an abnormal condition and should not be interpreted as having ceased unrest or the threat of eruptive activity. Under this status, there is a possibility of sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ash fall, and the release of lethal amounts of volcanic gas, which can pose a threat to areas within the volcano’s island.
Furthermore, the continuous degassing of high concentrations of volcanic SO2 poses a health risk to residents in communities that are frequently exposed to volcanic gas. As a result, Phivolcs strongly advises against entering Taal’s Permanent Danger Zone, especially in the vicinity of its main crater and the “Daang Kastila” fissure. Strict prohibition of entry is necessary to ensure the safety of individuals in these areas.
It is crucial for the public to remain vigilant and heed the warnings and guidelines provided by Phivolcs. The institute closely monitors the activity of Taal Volcano and provides regular updates to ensure the safety and well-being of the surrounding communities. By staying informed and following the instructions of local authorities, residents can mitigate the risks associated with the volcano’s unrest.
In conclusion, the recent increase in seismic activity and SO2 emission at Taal Volcano in the Philippines has raised concerns about the potential for eruptive activity. While the volcano remains at Alert Level 1, it is important to remember that the threat of volcanic hazards, such as steam-driven explosions and the release of volcanic gas, is still present. Residents in nearby communities should take necessary precautions and refrain from entering the Permanent Danger Zone. Phivolcs continues to monitor the situation closely and will provide updates to ensure the safety of the affected areas.
