Abstract: A method for calculating time-strains for two seismic data sets resulting from seismic exploration of the same subsurface structure uses selected subsets of data from the two seismic data sets to calculate time-shifts for each trace. A smooth function is fitted along each trace based on the calculated time-shifts a time derivative is applied to the smooth function to obtain time-strains along each trace.
