Ambient seismic noise tomography of the southern United States and seismic inversion with dictionary learning using unsupervised machine learning.
… the Empirical Green’s Function (EGF) through cross-correlation and cross-coherence. This mimics Rayleigh wave phase characteristics. We address the problem of non-stationary phases in Rayleigh wave extraction from ambient noise. Seismic interferometry assumes stationary phase dominance in EGF …
