The Indian government has announced it will measure the height of Mount Everest for the second time to assess whether it changed as a result of the 2015 Nepal earthquake. | The Indian government has announced it will measure the height of Mount Everest for the second time to assess whether it changed as a result of the 2015 Nepal earthquake. |

They added at the time that a ground survey and GPS or an airborne mission would be needed to determine whether the world's highest peak had seen a change in its height by a few centimetres. | They added at the time that a ground survey and GPS or an airborne mission would be needed to determine whether the world's highest peak had seen a change in its height by a few centimetres. |
Mr Rao told the BBC: "The Survey of India will work with the government of Nepal, which has agreed in principle to collaborate." | |
Everest's height will be assessed using a combination of GPS measurement and triangulation. | |
Mr Rao said it was an open question whether the quake had affected Everest's height. | |
"We don't know what happened, there's been no confirmed report. Some scientists do believe it has shrunk. But there's a school of thought it may have grown." | |
There will be about 30 people in the team, including three or four Indian scientists. | |
He told the Press Trust of India news agency that the team would take about a month to make its observations and another 15 days to compute and declare its data. |
