The more common terminology for event movement is seismic migration. Each primary reflection on an enhanced trace must be moved (or migrated) to the spatial position of the reflecting point at depth. In other words, each amplitude value on the enhanced trace is moved to its proper spatial location (the depth point). Migration can be accomplished by superposition of the processed traces. Such superposition is similar to that used in Huygens’ construction (Figures 4 and 5).
