shot depth The depth below ground level of a seismic source. If the source is non-explosive, it is the depth at which the source impulse is generated; if it is explosive, it is the depth to the top of the explosive, or to its mid-point if the length of the explosive material is small in relation to the depth of the hole, or to both top and bottom of the explosive charge (i.e. two shot depths) if it is very large.
