CALABARZON — Multiple local government units (LGUs) in the Calabarzon region and Metro Manila suspended classes on Monday due to a significant release of volcanic smog, or “vog,” from Taal Volcano. The affected areas include several cities and municipalities in Batangas, Cavite, and Laguna, as well as specific locales in the National Capital Region.
According to Philippines News Agency, the volcano has been on alert level 1, indicating low-level unrest, and has emitted 3,355 tonnes of sulfur dioxide flux daily since Thursday. This emission has led to vog conditions, characterized by a foggy atmosphere and potential health risks such as eye, throat, and nose irritations. Each affected LGU announced the suspension of face-to-face classes through their social media platforms, transitioning to modular or online learning modes.
In Batangas, cities and towns like Balete, Balayan, and Malvar, among others, have halted physical classes. Similarly, in Cavite, areas such as Silang, Mendez, and Indang have also moved to online classes. Laguna cities like Calamba and Biñan, and Los Baños followed suit. Moreover, Parañaque and Muntinlupa in Metro Manila suspended classes due to unhealthy air quality, with Muntinlupa shifting to asynchronous learning starting from 10 a.m.
The Office of Civil Defense (OCD) has been actively monitoring the situation, coordinating with Phivolcs and the Department of Environment and Natural Resources-Environmental Management Bureau (DENR-EMB) Calabarzon to assess ongoing conditions and provide necessary support. This proactive approach is aimed at managing the health risks associated with vog and ensuring the safety of residents in the affected areas.
