In mountaineering, the death zone refers to altitudes above which the pressure of oxygen is insufficient to sustain human life for an extended time span. This point is generally agreed as 8,000 m (26,000 ft), where atmospheric pressure is less than 356 millibars (10.5 inHg; 5.16 psi). [ 1 ]
Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly (loss of vital functions) or indirectly (unwise decisions made under stress or physical weakening leading to accidents). In the death zone, the human body cannot acclimatize, as it uses oxygen faster than it can be replenished.
The world’s highest mountain continues to draw climbers willing to risk their lives as they clamber past frozen corpses on their way to the top. ... sits along the edge of the death zone at ...
Locations of the world's 14 eight-thousanders, which are split between the Himalayan (right), and the Karakoram mountain ranges (left). The eight-thousanders are the 14 mountains recognized by the International Mountaineering and Climbing Federation (UIAA) as being more than 8,000 metres (26,247 ft) in height above sea level, and sufficiently independent of neighbouring peaks.
The “death zone” is the name given to the highest part of Everest, which is the area above 26,247ft (8,000m). The atmospheric oxygen there is so low that cells in the human body die in the ...
Makalu is the world's fifth-highest mountain at 8,481 meters (27,825 ft) above sea level. It is located in the Mahalangur Himalayas 19 kilometers (12 mi) southeast of Mount Everest on the China–Nepal border. As of December 2024, there had been 800 successful summits of Makalu and 50 deaths on the mountain. [1]
Helicopters flew up to 7,000 meters but were not able to locate the lost mountaineers. After the weather conditions worsened, the search and rescue operation was called off. Experts speculated that the three lost mountaineers would have perished by that time, as they were lost in the death zone, where the chance of survival was slim to none. [11]
All 14 summits in the death zone above 8000 m, called eight-thousanders, are located in the Himalaya and Karakoram mountain ranges. Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly by loss of vital functions or indirectly through wrong decisions made under stress or physical ...
