China and Nepal have teamed up to announce the new height of Mount Everest, the world’s highest mountain, under the 2019 memorandum of understanding (MoU). The announcement was delayed due to the Covid-19 pandemic.
Meanwhile, Nepal sent its own team to the summit in 2019, while China’s expedition began in May this year.
The two countries have historically disagreed on the official height but in 2019’s MoU has agreed to settle their differences.
China’s foreign ministry said, “The Chinese side Nepal’s claim that the snow height of Mount Everest is 8,848 meters, while the Nepali side recognized the Chinese claim that the rock height of the mountain is 8,844.43 meters.”
Earlier, all measurements have been conducted by US, European or Indian surveyors, rather than the countries where Everest sits.
“This body of work is a matter of pride for Nepal but is also a huge undertaking and with the whole world keenly waiting for the result, it has not been easy,” said Navin Manandhar, who helped develop the methodology for re-measurement.
According to the Guardian, the Everest height was first declared as 8,840m by the Great Trigonometric Survey (GTS) of India in 1856. It has fluctuated over time, depending on the surveyor and whether the measurement is taken at the highest rock point or the highest snow point –which is subject to change.
Christopher Pearson of the University of Otago in New Zealand told the Nepali Times, “The height of Everest is constantly changing due to tectonic activity, of which the 2015 Gorkha earthquake is only the most recent contribution.”
According to the newspaper, the two sides also use different sea-level points as a reference for their measurements. China uses the Yellow sea while Nepal’s location is closer to the Bay of Bengal coast.
