           Mt Everest grows by nearly a metre to new height

 The world's highest mountain Mount Everest is 0.86m higher than had been previously

 officially calculated, Nepal and China have jointly announced. Until now the countries

 differed over whether to add the snow cap on top. The new height is 8,848.86m (29,032 ft).

 China's previous official measurement of 8,844.43m had put the mountain nearly four metres

 lower than Nepal's. Everest Officials at Nepal's foreign ministry and department of survey

 said surveyors from both countries had co-ordinated to agree on the new height. The

 agreement to jointly announce the new measurement of the Earth's highest point was made

 during Chinese President Xi Jinping's visit to the Nepalese capital, Kathmandu last year.

 Chinese authorities had said previously Mount Everest should be measured to its rock height,

 while Nepalese authorities argued the snow on top of the summit should be included. The

 Chinese surveyors had calculated their figure after they measured the mountain in 2005.

 Nepal's government officials told the BBC in 2012 that they were under pressure from China

 to accept the Chinese height and therefore they had decided to go for a fresh measurement to

 "set the record straight once and for all". The 8,848m height, Nepal had been using for Mount

 Everest was determined by the Survey of India in 1954, but for the first time the country has

 now conducted its own measurement of the summit. Four Nepalese land surveyors spent two

 years training for the mission, before heading to the summit. "Before this, we had never done

 the measurement. ourselves," Damodar Dhakal, spokesman at Nepal's department of survey,

 told the BBC. "Now that we have a young, technical team [who could also go to the Everest

 summit], we could do it on our own," Mr. Dhakal said. Nepal's lead surveyor Khimlal Gautam

 lost his toe due to frostbite while on the summit to install height-measuring equipment last

 year. "For summiteers, scaling the highest peak means a great accomplishment. For us, it was

 just the beginning," Mr. Gautam had told BBC Nepali after his return. "Unlike other surveys

 of the Everest in the past, we chose 03:00 to minimise errors that could have been caused

 because of sunlight in the day time."

 Some geologists have suggested a major earthquake in 2015 may have had an impact on

 Mount Everest's height. The 7.8 magnitude earthquake killed nearly 9,000 people in Nepal,

 and caused an avalanche which buried parts of the base camp at the mountain.
