Acoustic full waveform inversion for 2-D ambient noise source imaging

A Datta, B Shekar, PL Kumar - Geophysical Journal International, 2023 - academic.oup.com
We present a method for estimating seismic ambient noise sources by acoustic full
waveform inversion (FWI) of interstation cross-correlations. The method is valid at local …
