Disclosed are methods, systems, and computer-readable medium to perform operations including: decomposing the seismic data into a plurality of sub-volumes, each sub-volume associated with a respective one of the plurality of frequency components; identifying a portion of the seismic data that includes one or more multiples, the multiples being seismic data associated with multiply reflected seismic energy; identifying, based on the plurality of sub-volumes, the one or more multiples within the portion of the seismic data; and determining, from the plurality of frequency components, a single frequency that gives rise to a predetermined continuity along a primary reflector affected by the one or more multiples.
