After battling a wildfire in Detroit, Oregon in September 2020, a firefighter named Don Tesdal noticed a strange thing, took a video of it, and uploaded it to Facebook to warn people. Don noticed that the fire was now burning underground, while the fire above ground had been extinguished. The fire had captured the root system of the entire forest, according to Don, this hidden fire could pose a threat not only to those walking on the ground above but also to those living nearby.
Underground burning makes the ground hollow from the inside and those who walk on it do not know what is going on inside, due to which they can sink inside it. Not only this, this kind of fire with 1200 degree temperature can burn anyone's shoes and can even burn a person standing above it. Whether you know it or not, similar underground fires have been burning in many other places around the world for years. This phenomenon is called "Coal-seam fire". What happens is that due to various reasons like industrial accidents, gas explosions, etc, the fire somehow reaches the underground coal layer and then gradually spreads. Because due to mining, the fire keeps getting little oxygen.

In Jharia, Jharkhand, there has been a fire under the ground for the last hundred years, while thousands of people have built houses above. Here, after coal mining got shut down, instead of covering it with the proper amount of sand, it was left in an improper way. In many areas, toxic fumes have always kept coming out from the walls of houses, which can fall anytime or the ground can collapse. These heavy fumes can also cause serious health problems. The underground fire has destroyed a dozen nearby settlements. Flames and gas smoke everywhere have been telling the frightening situation. According to a report, Rs 2311 crore has been spent so far to extinguish this fire, but the situation is getting worse every day. Coal worth more than 10 billion has been burnt to ashes so far due to underground fire. This fire is both a health and safety hazard.
