Seismic Resolution: Vertical and Horizontal

 · Seismic Resolution: Vertical and Horizontal Overview. Seismic resolution is the ability to distinguish between two features from one another. There are two types of seismic resolution, being vertical and horizontal. Vertical resolution determines the thickness of the beds, such as two close seismic responds corresponding to different depth levels.
