Example of forward modeling for ECr11. a OBS063, b OBS075, c OBS090, d OBS115. Vertical record sections with calculated travel times and ray diagram are shown for each OBS. The OBS data were processed through predictive deconvolution and band-pass filtered (4–20 Hz). A gain factor proportional to distance has been used to enhance the distant seismograms. The color of the calculated travel times corresponds to the ray path in the ray diagram
