The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
Dean's Blue Hole is a blue hole located in The Bahamas in a bay west of Clarence Town on Long Island and is the world's third deepest with a depth of 202 metres (663 ft), after the Taam Ja' Blue Hole in the Chetumal Bay and the Dragon Hole in the South China Sea. [1]
Its name means deep water in the Mayan language and, at over 420 metres (1,380 ft) deep, it is the deepest known blue hole. [1] Blue holes generate a distinctive blue color when seen from above and are typically only a few dozen meters deep. It was discovered in about 2003 by a local diver who followed a grouper that went into its mouth. The ...
Indeed, while TBJH was initially discovered in 2021, scientists only measured its depth down to 900 feet due to limitations in the echo-sounder technology — which calculates speed based on sound ...
The temperature deep within was 1,000 °C (1,800 °F), heat from a chamber of fire from which screaming could be heard. The Soviet Union had, in fact, drilled a hole more than 12 km (7.5 miles) deep, the Kola Superdeep Borehole , located not in Siberia but on the Kola Peninsula , which shares borders with Norway and Finland .
Dragon Hole is about 100 metres (330 ft) deeper than Dean's Blue Hole in the Bahamas. There are several fresh water sinkholes on land that are deeper than Dragon Hole. These include Mexico's Zacatón (335 metres (1,099 ft)), Pozzo del Merro in Italy (392 metres (1,286 ft)) [4] [5] and Hranice abyss in the Czech Republic (404 metres (1,325 ft)).

At a total depth of 339 meters (1,112 ft), it is one of the deepest known water-filled sinkholes in the world. [ 1 ] Using an autonomous robot, the underwater portion of Zacatón has been measured to be 319 meters (1,047 ft) deep (a 20-meter (66 ft) difference between the rim of cliff and surface of water adds to the total depth).
