Footage show smog from the Taal Volcano blanketing the skies over the Philippines capital Manila on Wednesday (June 30).
Onlooker Vhylchar Cainoy captured the haze outside his workplace in Makati Ayala.
He said: ‘The smog was so thick and painful to the chest and we not sure if it’s because of the sulfur from Mount Taal.’
Dangerous volcanic smog emerged from the Taal volcano in the Philippines causing limited visibility around the mountain on Monday morning.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) issued warning in the area after the volcanic smog or vog was detected coming out of Taal.
The agency said in a statement: ‘These atmospheric conditions, especially the near-absence of air movement, resulted in the formation of volcanic smog or vog that brought a pronounced haze over the Taal Caldera region.
‘It consists of fine droplets containing volcanic gas such as sulfur dioxide which is acidic and can cause irritation of the eyes, throat and respiratory tract in severities depending on the gas concentrations and durations of exposure.’
Vog is a form of air pollution that results when sulfur dioxide and other gases and particles emitted by an erupting volcano react with oxygen and moisture in the presence of sunlight.
