During a competition to see who could dig the longest hole in the world, BBC received recordings of sounds supposedly coming from within the hole. Initially aired on the Art Bell show, the clip whipped speculators in to a frenzy, and went viral instantly.
The legend holds that a team of Russian engineers purportedly led by an individual named “Mr. Azzacov” in an unnamed place in Siberiahad drilled a hole that was 14.4 kilometres (8.9 mi) deep before breaking through to a cavity. Intrigued by this unexpected discovery, they lowered an extremely heat-tolerant microphone, along with other sensory equipment, into the well. The temperature deep within was 1,000 °C (2,000 °F)—heat from a chamber of fire from which (purportedly) the tormented screams of the damned could be heard. However, the recording was later found to be looped together from various sound effects, sometimes identified as the soundtrack of the 1972 movie Baron Blood.
The Soviet Union had, in fact, drilled a hole more than 12 kilometres (7.5 mi) deep, the Kola Superdeep Borehole, located not in Siberia but on the Kola Peninsula, which shares borders with Norway and Finland. Upon reaching the depth of 12,262 metres (40,230 ft) in 1989, some interesting geological anomalies were found, although they reported no supernatural encounters. Temperatures reached 180 °C (356° F), making deeper drilling prohibitively expensive.
