Etymology

Origin of earthshaking

First recorded in 1350–1400; Middle English; see origin at earth, shaking

Explanation

When something is earthshaking, it’s so loud or significant that it feels like the whole world could tremble in response. Whether it’s a sound loud enough to shake the earth or an event significant enough to impact the entire world, earthshaking moments leave a lasting impression. A thunderous explosion that can be felt all over town is an example of a literally earthshaking event. In a figurative sense, an earthshaking discovery would be the existence of life on other planets.
