landslip

noun

Etymology: From land + slip.

1. The sliding of a mass of land down a cliff or slope; a landslide.

   “This landslip appears to have been occasioned by the freezing of the springs in the chasms of the hill; the expansive force of the ice causing a separation at the base of the cliff beneath the hill, the ground began to move forward, and the lands of the farm, being pressed on by the descending mass, were torn from their original foundations.”

   “And wasn’t it a sight to see, / When, ere his song was ended, / Like some great landslip, tree by tree, / The country-side descended;”
