Earthshaking → It is formed from "earth" (from Old English "eorþe", meaning the ground or soil) and "shaking" (from the verb "shake", which has Germanic origins meaning to move back and forth). The word "earthshaking" describes something that causes the ground to move or tremble significantly, often used metaphorically to indicate something of great importance or impact.
Think of the ground ('earth') moving or trembling ('shaking') — that's why earthshaking means something that causes a significant tremor or impact.
