How Fast Is Mount Everest Growing?

Mount Everest is not a mountain chain—it's a single summit within the Himalayan range. The Himalayas are growing due to the ongoing India–Eurasia collision.

Average uplift rate: ~4 mm/year (0.15 in/yr) — measured by GPS across the range.

Nuances

• Rates vary locally (fault geometry, erosion).
• Erosion (glacial, fluvial, seismic) counters uplift; net height change may be near zero.
• 2015 Gorkha earthquake caused ~1 m co-seismic slip but also triggered massive landslides.
• Everest's summit height was jointly re-measured by Nepal & China in 2020: 8,848.86 m (29,031.7 ft).

The Himalayas are a dynamic, young (50 Ma), active orogen—unlike the ancient, eroded Appalachians.
