**SOUNDS FROM THE HOLE TO HELL **
In 1989, Dr. Dimitry Azacov and a group of scientists were working on a borehole drilling project in Siberia. When the drill reached 14.4 kilometers, or 9 miles deep, the drill bit started rotating wildly. It had somehow broken through solid rock and into a hollow area under the earth's crust. This cavity wasn't supposed to be there.
When the drill returned to the surface, it was literally glowing red hot. This, also, was unexpected. The temperatures at these depths should be about 100 degrees. 150 degrees at most. Instruments were reading temperatures of over 1,100 degrees. Dr. Azacov said, "It seems like an inferno in the center of the Earth".
The next discovery, according to Dr. Azacov, was the most shocking; and caused some people to leave the project. At the surface, they heard strange sounds coming from the hole. At first, the engineers thought it was their equipment. So they shut down all the machinery, but the sound was still there.
Part of the research done at the site was recording the sound of the movement of the earth using specialized microphones.
So they lowered one of these microphones into the hole. Even though it was designed to operate at high temperatures, it overheated in just a few seconds. But a few seconds was enough to prove the sound was definitely coming from the Earth's interior. He said the sound was unsettling.
9 miles below the surface, in a superheated cavern, they heard humans voice screaming in pain.
Let's find out why.
