Normal Moveout (NMO) is a concept used in seismic data processing, particularly in the context of time-domain analysis of seismic reflection data. It refers to the phenomenon where seismic waves from a point source reflect off subsurface geological layers and travel at various angles to reach the surface. When seismic waves propagate through the Earth, they travel at different velocities depending on the geological materials they encounter.
