An earthquake cannot physically occur at a depth of 0 km or -1km (above the surface of the earth). In order for an earthquake to occur, two blocks of crust must slip past one another, and it is impossible for this to happen at or above the surface of the earth. So why do we report that the earthquake occurred at a depth of 0 km or event as a ...2 Citations. Abstract.

High-resolution shallow reflection seismics can now be successfully applied to geological, engineering and environmental problems (e.g. Meekes et al. 1990, Pullan & Hunter 1990, Miller & Steeples 1994). The most commonly applied shallow reflection … A common-depth-point (CDP) gather is defined by the industry and by common usage to be the same thing as a common-midpoint (CMP) gather. But in this book a distinction will be made. A CDP gather is a CMP gather with its time axis process assigns each trace to a single shot, receiver, common depth point, inline, crossline, and offset bin. Other individual values for each trace, shot, receiver, CDP, and offset bin are also computed.

This is called the Common Depth Point (CDP) method because the data is repeatedly recorded over increasing source to receiver offsets, but with the raypaths reflecting off the same depth location on each geological surface. The CDP gather shown in figure 7 (b) shows the recorded traces for all source / receiver pairs.
