Mount Everest Is Still Growing: ~1 cm Per Year

Yes, Mount Everest grows about 4 mm (0.16 in) to 1 cm (0.4 in) annually—driven by the ongoing collision of the Indian and Eurasian tectonic plates.

The Mechanism

The Indian Plate pushes northward at ~5 cm/year. Crustal shortening thickens the Himalaya, uplifting Everest and its neighbors. Simultaneously, erosion (glacial, fluvial, seismic) wears the summit down. Net growth is the balance.

Measurement

• GPS/GNSS surveys (1990s–present) confirm ~4 mm/yr horizontal convergence, ~1 mm/yr vertical at summit.
• 2020 China–Nepal joint survey: 8,848.86 m (new official height).
• Earthquakes (e.g., 2015 Gorkha) can cause sudden subsidence or uplift of meters.

Everest is a dynamic feature, not a static monument. It rises as India keeps driving into Asia.
