India will re-measure Mount Everest's height to check 2015 Nepal earthquake impact

Some scientists believe it has shrunk by one metre, said the Survey of India.

A team from the Survey of India will soon visit Nepal to measure the height of Mount Everest and figure out whether the 2015 earthquake had reduced its height. Surveyor General of India Swarna Subba Rao told PTI on Tuesday that the project will start in two months’ time in collaboration with the government of Nepal. The height of Mount Everest was 8,848 metres (29,028 feet) above sea level when last recorded.

The decision was taken after speculations among scientists about the Nepal earthquake impact on the mountain. According to satellite data, the quake reduced the height of the peak by around one metre. “We don’t know what happened, there’s been no confirmed report. Some scientists do believe it has shrunk,” Rao told BBC. The team will have around 30 scientists, including three or four Indians.

They will observe the peak for about a month and then it will take around 15 days to compute and publish the data. The height will be measured in two ways - using the Global Positioning System and a ground method. “It [The GPS] is a survey instrument. If you put it on the summit, say for 10 minutes, it tells you the height. The second is...triangulation. The height can be calculated from ground,” Rao added.

This is the second time that the height of Everest is being measured by India. “Everest’s height was declared, if I remember correctly, in 1855. We are re-measuring it. It is almost two years since the major Nepal earthquake,” said Rao, adding that the exercise would also help future studies.

An earthquake, measuring 7.8 on the Richter Scale, hit Nepal in April, 2015. Thousands of people were killed while buildings were reduced to rubble. The quake changed the landscape of the region.

Following a mountaineer as he reaches the summit of Mount Everest

Accounts from Vikas Dimri’s second attempt reveal the immense fortitude and strength needed to summit the Everest.

Vikas Dimri made a huge attempt last year to climb the Mount Everest. Fate had other plans. Thwarted by unfavourable weather at the last minute, he came so close and yet not close enough to say he was at the top. But that did not deter him. Vikas is back on the Everest trail now, and this time he’s sharing his experiences at every leg of the journey.

The Everest journey began from the Lukla airport, known for its dicey landing conditions. It reminded him of the failed expedition, but he still moved on to Namche Bazaar - the staging point for Everest expeditions - with a positive mind. Vikas let the wisdom of the mountains guide him as he battled doubt and memories of the previous expedition. In his words, the Everest taught him that, “To conquer our personal Everest, we need to drop all our unnecessary baggage, be it physical or mental or even emotional”.

Vikas used a ‘descent for ascent’ approach to acclimatise. In this approach, mountaineers gain altitude during the day, but descend to catch some sleep. Acclimatising to such high altitudes is crucial as the lack of adequate oxygen can cause dizziness, nausea, headache and even muscle death. As Vikas prepared to scale the riskiest part of the climb - the unstable and continuously melting Khumbhu ice fall - he pondered over his journey so far.

His brother’s diagnosis of a heart condition in his youth was a wakeup call for the rather sedentary Vikas, and that is when he started focusing on his health more. For the first time in his life, he began to appreciate the power of nutrition and experimented with different diets and supplements for their health benefits. His quest for better health also motivated him to take up hiking, marathon running, squash and, eventually, a summit of the Everest.

Back in the Himalayas, after a string of sleepless nights, Vikas and his team ascended to Camp 2 (6,500m) as planned, and then descended to Base Camp for the basic luxuries - hot shower, hot lunch and essential supplements. Back up at Camp 2, the weather played spoiler again as a jet stream - a fast-flowing, narrow air current - moved right over the mountain. Wisdom from the mountains helped Vikas maintain perspective as they were required to descend 15km to Pheriche Valley. He accepted that “strength lies not merely in chasing the big dream, but also in...accepting that things could go wrong.”

At Camp 4 (8,000m), famously known as the death zone, Vikas caught a clear glimpse of the summit – his dream standing rather tall in front of him.

It was the 18th of May 2018 and Vikas finally reached the top. The top of his Everest…the top of Mount Everest!

Vikas credits his strength to dedication, exercise and a healthy diet. He credits dietary supplements for helping him sustain himself in the inhuman conditions on Mount Everest. On heights like these where the oxygen supply drops to 1/3rd the levels on the ground, the body requires 3 times the regular blood volume to pump the requisite amount of oxygen. He, thus, doesn’t embark on an expedition without double checking his supplements and uses Livogen as an aid to maintain adequate amounts of iron in his blood.
