Mount Everest's Hidden Growth Spurts: The Role of Isostatic Rebound

Mount Everest, Earth's tallest mountain, is experiencing unexpected growth due to isostatic rebound, a geological process triggered by river system changes. This has caused a significant uplift in the region, with scientists estimating an additional height increase of 49-164 feet. The findings highlight Earth's dynamic nature.

Mount Everest, traditionally known as Earth's tallest mountain, is growing more than scientists anticipated. A study reveals that the iconic peak has gained between 49 to 164 feet due to a geological phenomenon called isostatic rebound. This process occurs when land masses rise as surface weight diminishes.

Researchers attribute this unexpected growth to the merger of the Kosi and Arun rivers, which took place around 89,000 years ago. The rivers' confluence accelerated erosion, reducing regional weight and prompting the Himalayas' uplift. This geophysical activity explains about 10% of Everest's annual elevation increase.

Similar isostatic rebound effects are observed globally, notably in Scandinavia. The study, co-conducted by geoscientists from China University of Geosciences and University College London, underscores the planet's dynamic nature, emphasizing ongoing changes in Earth's crust.
