  • Project will examine whether earthquake and changing wind speeds have affected peak’s snowcap
  • Survey team hoping the BeiDou satellite navigation system and other Chinese technology can help them find the answer

China is sending a surveying and mapping team to the summit of Mount Everest this month in a bid to end the long-running debate over the precise height of the world’s tallest mountain.

The mission was announced on Wednesday at one of the mountain’s base camps in Tibet, where a team of 53 surveyors has been making technical preparations since March 2. The team will use China’s BeiDou navigation satellite system and Chinese surveying instruments for the project.

Mount Everest – known as Sagarmatha in Nepal and Qomolangma in Tibet – lies in the Himalayas on the border between China and Nepal. The two countries have long disputed whether measurements of the mountain should include its snowcap or be limited to the rock base.

In 2005, a Chinese expedition assessed the peak and measured the height from both the rock base and from the top of the snowfall. The result, a rock height of 8,844.43 metres (29,017.2 feet), was declared by China to be the most accurate and precise measurement to date.

Nepal has long held that Everest’s snowcap should be included, putting the iconic peak at 8,848 metres, a height which is widely accepted. However, geologists believe the snowcap may have shrunk by several centimetres after the magnitude 8.1 earthquake in 2015. Changing wind speeds are also believed to have affected it.

Following a state visit to Nepal by Chinese President Xi Jinping in October, the two countries agreed to jointly launch a scientific research project to determine the exact height of Everest, recognising the peak as “an eternal symbol of the friendship between the two countries”.
