Provided is a method of processing elastic wave data, the method including selecting some elastic wave traces as a first label from among a plurality of elastic wave traces received without at least some elastic wave traces missing from whole elastic wave data, training an interpolation model on a machine learning basis by using at least two or more of remaining elastic wave traces except for the first label and the first label, restoring the at least some elastic wave traces missing from the whole elastic wave data by using the trained interpolation model, training an extrapolation model on a machine learning basis by using an elastic wave trace selected as a second label from among a plurality of elastic wave traces included in whole restored elastic wave data and at least two or more of remaining elastic wave traces except for the second label, and generating an additional elastic wave trace, which have not been included in the whole elastic wave data, by using the trained extrapolation model.
