Jharia is a notified area and one of eight development blocks in Dhanbad district in Jharkhand state, India.
Jharia is famous for a coal field fire that has burned underground for nearly a century. The first fire was detected in 1916. According to records, it was the Khas Jharia mines of Seth Khora Ramji Chawda (1860-1923), who was a pioneer of Indian coalmines, whose mines were one of the firsts to collapse in underground fire in 1930. Two of his collieries, Khas Jharia & Golden Jharia, which worked on maximum 260-foot-deep shafts, collapsed due to now infamous underground fires, in which their house & bungalow also collapsed on 8 November 1930, causing 18 feet subsidence and widespread destruction.
The fire never stopped despite sincere efforts by mines department and railway authorities and in 1933 flaming crevasses lead to exodus of many residents. The Bihar 1934 earthquake led to further spread of fire and by 1938 the authorities had declared that there is raging fire beneath the town with 42 collieries out of 133 on fire.
In 1972, more than 70 mine fires were reported in this region. As of 2007, more than 400,000 people who reside in Jharia are living on land in danger of subsidence due to the fires.
