Taal Volcano Smog: No Classes in Cavite and Batangas on All Levels (Private and Public)

September 15, Thursday – The Philippine Institute of Volcanology and Seismology (Phivolcs) confirmed that Taal Volcano began emitting volcanic smog or vog. The agency said it could adversely affect the health and damage crops and infrastructure.

Afterward, several local government units in Batangas and Cavite announced the suspension of classes. 

Why Vog is a Health Threat?

Vog has fine droplets containing volcanic gas such as sulfur dioxide — a chemical compound, SO ₂, and known toxic gas responsible for the odor of burnt matches. Vog’s chemical compound can irritate the eyes, throat, and respiratory tract.

Aside from concern, Phivolcs added that acid rain could also be generated during rainfall and volcanic gas emissions. 

Despite the possibility of acid rain, Philvolcs maintained Taal Volcano under Alert Level 1.
