Joint seismic traveltime and waveform inversion for near surface imaging
SEG Technical Program Expanded Abstracts 2014
The first-arrival traveltime tomography is currently a standard approach for imaging the near surface structures. But it cannot resolve complex situation such as hidden lowvelocity layers. Early arrival waveform inversion is a robust approach for dealing with complex structures, but it may take significant computational efforts. Furthermore, in practice, we found that the results from waveform inversion may not allow fitting the first arrival traveltimes anymore because of nonuniqueness of thedoi:10.1190/segam2014-1501.1 fatcat:u46skdbhv5bh3ov5nldcaawggy
