The Reality Of Hell
We can tell from Scripture, the present hell, is somewhere in the heart of the earth itself. It is also called 'the pit' (Isa. 14:9, 15: Ezek. 32:18-21) and 'the abyss' (Rev. 9:2). . .

The Bible writers certainly themselves believed hell to be real and geographically located 'beneath' the earth's surface. . .
The Birmingham News, April 10, 1987 had an article entitled "Earth's Center Hotter Than Sun's Surface, Scientists Say". The article stated that scientists have recently discovered, "THE EARTH'S INNER CORE HAS A TEMPERATURE OF OVER 12,000 DEGREES FAHRENHEIT!"
A volcano is simply defined as an opening in the earth's surface crust through which molten lava, ash, and gases are ejected.
