The rising global interest in coal fires

In eastern India, north of the Damodar River, approximately 70 fires are burning in the Jharia coalfield, the largest coalmine fire complex in the world. The majority of fires in Jharia ignite when coal, exposed to air during mining operations, spontaneously combusts. Particulate matter and noxious gases emitted from the burning coal — including sulfur, carbon and nitrogen oxides, and hydrocarbons released at the surface from gas vents, ground fissures and the soil — have caused illnesses that range from stroke to chronic obstructive pulmonary disease.
