India’s tectonic plate keeps shoving into Eurasia, slowly lifting the Himalayas. Averaged over time, Everest gains roughly 4 mm of height each year from that continental collision.
Earthquakes can rewrite the scoreboard overnight — raising or dropping peaks by centimeters in a single shock. Growth is not a smooth elevator ride; it is a stutter of stress and release.
The millimeter gains remind us mountains are alive on geologic clocks. Today’s summit is a temporary high point in a collision still underway under Asia.
