What is the fastest that a mountain can grow?

    The world’s fastest growing mountain is Pakistan’s Nanga Parbat. It is increasing its height at a whopping 0.27 inches per year, which should soon make it the eighth instead of ninth highest mountain!

    Volcanoes can grow at great rates as their erupted material comes out on the surface. Paracutin went from zero to more than 1000 feet above ground level in about a year in 1943-44. Surtsey came from undersea and went from sea level to more than 1600 feet in just a few days.

    Non-volcanic mountains grow in general at the tiny rates suggested in the other answer, althogu occasionally earthquake offsets can affect mountain heights by a few meters at one shot.
