From: P-wave velocity structure in the southernmost source region of the 2011 Tohoku earthquakes, off the Boso Peninsula, deduced by an ocean bottom seismographic survey

(a) Ray diagrams of all OBS calculated by the travel time inversion. The black lines show all turning and reflected waves. (b) Resolution of the velocity nodes calculated by the travel time inversion. Resolution values are represented by a grey scale. The contour is drawn for the resolution greater than 0.5. The contour interval is 0.1. Resolution in the sedimentary layer is not calculated because the velocity was determined by the tau-p method.
