Estimation of seismic structural correlation can provide useful information for structural interpretation, events correlation enhancement, signal-to-noise ratio (SNR) improvement, subsurface modeling, and geophysical inversion. In this letter, we propose a Shannon entropy-based method to measure seismic local correlation and further enhance the correlation of seismic events. The proposed method is derived from the local plane-wave model and formulated as a Shannon entropy form. The probabilities are calculated along with the coordinate direction of local slope and estimated by solving two least-squares problems in local areas. Application to both synthetic and field data sets demonstrates the superior performance of the Shannon entropy-based method over traditional alternatives.
