River piracy boosts Mount Everest's height, scientists find

yahoo.com

Scientists have found that a geological event known as "river piracy" contributed to Mount Everest's height increase. About 89,000 years ago, the Kosi River captured the Arun River, leading to enhanced erosion and isostatic rebound, which lifted Everest and nearby peaks. Recent GPS measurements indicate Everest is growing at 0.08 inches (2 millimeters) per year, double the previously expected rate. This growth is attributed to the Kosi River's increased flow, which eroded more rock and caused surrounding areas to rise. The study highlights the interplay between river systems and mountain formation, suggesting that sudden changes in river courses can significantly impact landscape elevation. Researchers emphasize the need for further fieldwork to confirm these findings.
