Mount Everest movement expedition

Graphic News

February 17, 2017 -- Amid speculation Nepal’s deadly 2015 earthquake might have caused Mount Everest to shrink, India is dispatching an expedition to the summit to confirm whether the world’s highest mountain is indeed still 8,848 metres above sea level.

Data from the European Space Agency's Sentinel-1A radar satellite suggests Everest’s height fell by 2.8 centimetres.

Interferograms over Kathmandu, Nepal, generated from two Sentinel-1A radar scans on April 17 and April 29 April 2015 --before and after the April 25 earthquake -- indicate vertical movement of up to 9m, with 3m of lateral movement in Kathmandu

The radar images reveal that some of the world's tallest peaks -- including Mount Everest -- dropped by about 1 inch 2.5 cm, according to UNAVCO, a geoscience research consortium. That's because the Earth's crust relaxed in the areas north of Kathmandu after the earthquake released pent-up strain.

The Indian expedition is estimated to cost $800,000 for a team of 30-plus people to ascend the mountain. At the base camp, the team will install a signal receiver with a clear line of sight to the peak.

Scientists will measure signals sent and received from satellites for five weeks and measure the time it takes for the transmissions to bounce back and forth. Scientists will also employ triangulation, a traditional method of determining a mountain's height, as a backup calculation.

NEW GRAPHIC NEWS - a new website for a new era, coming soon…

And it will be worth the wait! The Graphic News website is undergoing a complete redesign. The new site will not only see improvements in terms of speed and user experience, but will also include many new features. For example, existing subscribers will be able to manage their accounts online via a group dashboard, and add selected graphics to lists for project planning (and which can be shared across the group).

Existing users will need to register individually - we’ll be sending instructions to our main contacts at each group and will be on hand to help you through the process, which we hope will be seamless!
