Mount Everest may have shrunk following a massive earthquake two years ago — and now the world’s tallest peak is set to be remeasured, according to reports.

Mount Everest came in at 29,029 feet — or more than 5 miles — when it was last measured in 1955.

But because of a 7.8-magnitude earthquake that rocked Nepal in 2015, the mountain may have been cut down by as much as 3 feet, the BBC said.

Engineers with the Survey of India will set off on an expedition in the next two months to measure the mountain using two methods — GPS and a ground system known as triangulation.

Triangulation involves measuring the distance between two points on the ground and measuring the angles between the top of the mountain and each point.

“We don’t know what happened, there’s been no confirmed report,” said Surveyor General of India Swarna Subba Rao. “Some scientists do believe it has shrunk. But there’s a school of thought it may have grown.”

The expedition is expected to take a month and another two weeks to calculate the data, Rao told the Press Trust of India.

Nepalese officials told the BBC that no agreement had been reached with India and that the country had its own plans to perform the measurement.
