The success rate of climbing Everest has doubled for 30 years. The death rate remains the same…

Elevation 8,776m Everest is known as the world’s highest peak. It is also a place where more than 500 climbers visit every spring. According to a research team at the University of Washington and UC Davis, the success rate of climbing Everest has doubled over the past 30 years as the number of climbing has increased significantly.

The results of the research published this time follow the surveys conducted from 1990 to 2005, and the research team is comparing data from 2005 to 2019 with previous surveys. According to the research team, 2,211 climbers attempted to climb Everest from 1990 to 2005, and 3,620 visitors from 2005 to 2019. The number of climbers challenging Everest is increasing recently.

In addition, the proportion of women among climbers increased from 9.1% in 1990-2005 to 14.6% in 2005-2019. In addition, the number of hikers aged 40 and over increased from 38.7% in 199-2005 to 54.1% in 2005-2019.

In addition, it was found that the percentage of climbers who successfully climbed Everest increased from one-third in 1990-2005 to two-thirds in 2005-2019. Meanwhile, the mortality rate of hikers attempting to climb Everest has remained almost unchanged at 1% for 30 years.

Looking at the success rate and mortality rate by 10 years from 1950 to 2019, the success rate from 20 to 30% until the 1980s continued to rise after the 1990s, exceeding 60% from 2010 to 2019. Meanwhile, the mortality rate remains unchanged regardless of the times.

The research team says that increasing the success rate can take a number of factors into account. Raymond Huey, an emeritus professor of biology at the University of Washington, pointed out that one of these factors was the dramatic improvement in the weather around Everest and the ability for climbers to gain more information after the storm broke out in May 1996 and the mass disaster of Everest broke out. .

In addition, because ropes for pioneering climbing are also arranged on popular routes, it is said that the ease of riding can lead to an increase in the success rate. Not only that, but the accumulated experience of mountaineers is also affecting. Emeritus Professor Huey said that Everest is still a dangerous mountain, and the Everest climb is a goal that goes beyond the limits for most people. It is revealed that it can be helpful in making judgments based on information on whether or not. Related information can be found here .
