In researching different elements of Silent Hill, screenwriter Roger Avary came across a town called Centralia which is in Pennsylvania. Centralia planted the seed for what developed into the town of Silent Hill.
As recently as 1981 there were over 1,000 residents living in Centralia, although the population has now dwindled to 11, as a result of a 40 year mine fire burning beneath the borough. Not unlike Silent Hill, which was left deserted since devastating coal fires ravaged the town and its people.
A trash fire was lit in an abandoned mine pit in Centralia, in 1962. The fire ignited an exposed vein of coal and spread throughout the mines beneath the borough. Several attempts have been made and millions of dollars have been spent unsuccessfully to extinguish this fire, that still burns today.
