India is currently the world's third-largest energy consumer. A significant proportion of the production for internal energy needs comes from Jharia coal mines in Jharkhand state. Underground fires have been burning for more than a century. But in recent decades open-cast mining has also brought the flames to the surface with devastating consequences for the population. The land is extremely susceptible to subsidence, putting at risk the lives of the inhabitants, who get injured or even die after being sucked into flaming sinkholes in the ground.
