1. A computer-implemented method for automatically tracking faults in a 2-D or 3D seismic data volume or cross-section, comprising:

  • (a) decomposing the seismic data into local slownesses for seismic data recorded in time, or slopes if the seismic data have undergone depth migration, using a programmed computer; and

    (b) identifying voxels in the seismic data which when decomposed into slownesses or slopes span a broader range of slownesses or slopes than other voxels in the seismic data, thereby forming a fault-highlighted data volume or cross-section.
