LOS BAÑOS, Laguna (PIA) – The Office of the Civil Defense (OCD) Calabarzon has reassured the public that there is “nothing to worry” about Taal Volcano’s recent degassing activities as the situation remains stable, and shows no immediate signs of an impending eruption.
During the Kapihan sa Bagong Pilipinas with the Department of National Defense, OCD Calabarzon Regional Director and Calabarzon Disaster Risk Reduction and Management Council Chairperson Carlos Eduardo Alvarez III explained that the current activity at Taal Volcano is influenced by the region’s humid temperatures which then interacts with the volcano’s geothermal features, leading to increased steam emissions and degassing.
“Taal is on alert level 1 as usual, it’s degassing. I think what happened is very humid, there is no wind around Taal area and also in other areas around Metro Manila and that’s why when it was released, the sulfur gas stayed still and was not blown away by the wind that is why there was a vog,” he explained.
Volcanic smog, commonly referred to as vog, is a type of air pollution that occurs when volcanic gases, particularly sulfur dioxide (SO₂), are released into the atmosphere during volcanic activity. When these gases interact with sunlight, oxygen, dust, and moisture in the air, they undergo chemical reactions that produce a visible haze or smog.
Vog can spread over large areas depending on wind patterns and can have significant environmental and health impacts to people with respiratory conditions, as it can exacerbate symptoms like coughing, shortness of breath, and throat irritation.
Alvarez reminded the public about the potential harm that the smog can cause and urged them to take necessary precautions, such as staying indoors, using air purifiers, and avoiding outdoor activities in affected areas.
“But nothing to worry about Taal Volcano, as it’s still on Alert Level 1. There’s degassing and the bad part is the sulfur gas emission is not good for our body, so better if we can stay home and if we really need to go out, i think best to wear a mask, it can irritate our eyes” he said.
Alvarez also advised the public to stay informed through official channels and to follow any guidance or updates provided by the OCD and PHIVOLCS. While vigilance is necessary, the current level of activity does not pose a significant threat at this time.
The OCD ensures that they are in coordination with PHIVOLCS for the close monitoring of volcanic activities, and with other RDRRMC member agencies to ensure the safety of residents in the surrounding areas. (AM/PIA-4A)
