Increased SO2 Emission from Taal Volcano Raises Concerns
Authorities urge the public to remain vigilant amid the recent rise in sulfur dioxide (SO2) emission from Taal Volcano. This sharp increase in SO2 levels has sparked warnings about the potential formation of volcanic smog, commonly known as vog, which could affect health.
The Philippine Institute of Volcanology and Seismology (Phivolcs) reported that Taal Volcano’s SO2 emission surged from 450 tonnes on August 27 to 4,514 tonnes by August 30. This tenfold rise indicates significant fluid movement or changes in volcanic gases beneath the surface.
Understanding the SO2 Emission Spike and Its Implications
Phivolcs Director Teresito Bacolcol explained that the sudden release of large volumes of volcanic gas might result from increased pressure or magma movement underground. However, he emphasized that this does not necessarily signal an imminent eruption.
“This does not mean that an eruption will occur immediately. The public, however, should be aware that SO2 could produce vog which can be harmful to health,” Bacolcol said in an interview with local officials.
Current Alert Status and Volcanic Activity
Despite the elevated SO2 emission, Taal Volcano remains under Alert Level 1, which indicates low-level unrest. Phivolcs noted that other volcanic activity parameters, such as volcanic earthquakes, have decreased recently.
From midnight of September 1 to midnight of September 2, only three volcanic earthquakes were recorded. This contrasts with the 11 volcanic quakes observed on August 30 and 31, signaling a decline in seismic activity.
Safety Measures and Public Advisory
Officials strongly advise the public to avoid entering Taal Volcano Island. The risk of sudden steam-driven or weak phreatomagmatic eruptions remains present, posing a danger to visitors and residents in nearby areas.
Phivolcs also mentioned that recent rainfall has hampered new SO2 measurements because rain disperses the gas quickly, making accurate monitoring more challenging.
Health Precautions Amid Vog Formation
Community members and local leaders remind residents to take precautions against vog, which may cause respiratory issues and other health problems. Wearing masks and limiting outdoor activities during high SO2 levels are recommended to minimize exposure.
The situation at Taal Volcano continues to be closely monitored by experts. Updates will be provided as new data becomes available to ensure public safety.
