CEBU CITY, Philippines — Air quality in parts of Cebu has remained within the “good” range following the eruption of Mt Kanlaon on Thursday, July 9. But environmental authorities are warning residents not to let their guard down as volcanic gases carried by prevailing winds could still lead to acid rain.
In an advisory issued Friday afternoon, July 10, the Department of Environment and Natural Resources–Environmental Management Bureau in Central Visayas (DENR-EMB-7) said continuous air quality monitoring showed particulate matter levels remained within the “good” category.
However, the agency said south-southwest winds continue to carry sulfur dioxide (SO₂) and other volcanic gases across the region. With the ongoing rainy weather, these gases may combine with atmospheric moisture and form acid rain.
