Generally, full waveform inversion is a non-linear data fitting process between synthntic data and observed data. We aim at collect physical properties of subsurface with rich information come from active or passive seismic data through solve the wave equation.
Below is comparison between different tomography models. The middle one CVM-S4.26 is generated by our group with Full waveform inversion method, which shows a promising future for wide application in seismic velocity imaging.
CVM-S4.26 is a Full-3D tomography model for Southern California. What I am doing right now is to expand the research to State-wide California (shown as left) as well as improve the model by taking considerision of attenuation and crustal anisotropy as well as improving computing efficiency.
