👉 Selenodesy is a type of seismological phenomenon where the movement of a line segment or a point on Earth's surface can be observed as an oscillation in seismic waves. This phenomenon occurs when the ground shakes due to the movement of a line segment, such as a selenode (a small piece of rock that can move), which is moved by the shaking.
The term "selenodesy" was coined by physicist and geologist Robert B. Mather in 1
