Answer:
In 1983, engineers studying the fire concluded that it could burn for 250 years and could spread over nearly 4,000 acres.
Step-by-step explanation:
Centralia in Pennsylvania is a city that has a fire that will last for about 250 years and that has already consumed more than 15 square kilometers, having enough strength to spread over 4,000 acres. This fire did not happen by chance, but because of the creation of a landfill in an old coal mine. The problem is that before this landfill was created, the holes made by the coal mine were not closed, which caused many underground meters to be filled with garbage. One day, uncomfortable with the amount of garbage accumulated, the citizens and the city government decided to set fire to the whole landfill, which caused the centenary fire that will last for 250 years, according to experts.
