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.
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]
A giant hole in the earth is breaking open the land in Siberia, and photos from space show it's growing rapidly. It resembles a stingray, a horseshoe crab, or a giant tadpole.
The depression is in the form of a one-kilometre-long gash up to 100 metres (328 feet) deep, and growing, in the East Siberian taiga, located 10 km (6.2 mi) southeast of Batagay and 5 km (3.1 mi) northeast of the settlement Ese-Khayya, about 660 km (410 mi) north-northeast of the capital Yakutsk.
Bristol Bay is the portion of the Bering Sea between the Alaska Peninsula and Cape Newenham on mainland Southwest Alaska. The Bering Sea ecosystem includes resources within the jurisdiction of the United States and Russia, as well as international waters in the middle of the sea (known as the "Donut Hole" [8]). The interaction between currents ...
Temperatures typically reserved for the harsh winters in Siberia have inundated portions of the central United States, shattering temperature records, creating travel nightmares and drastically ...
But this hole reaches just 7.6 miles into the crust and took 20 years to complete because conventional equipment, such as mechanical drills, can’t handle the conditions at those depths.
A different schist belt may underlie the Brooks Range and is known from deep boreholes in the vicinity of Prudhoe Bay, reaching greenschist and blueschist on the sequence of metamorphic facies. Precambrian metasedimentary gneiss is found in the Kigluaik Mountains on the Seward Peninsula, while in southeast Alaska, additional Precambrian rocks ...
