Systems and methods for identifying anomalies in a subterranean formation based on seismic attributes include: receiving a seismic cube and a seismic surface, wherein the seismic cube includes traces recorded at receivers deployed to collect seismic data, and the seismic surface is picked on the seismic cube; extracting seismic wavelets with a selected length from the seismic cube along an intersection with the seismic surface for each spatial coordinate associated with the seismic surface; determining a population trend of the seismic wavelets; and generating a attribute map based on comparing each of the seismic wavelets to the population trend.
