Orientations of a σ1 axis and b σ3 axis obtained by stress tensor inversions of events that occurred in the Pacific plate. Orientation of the best-fit σ1 axis or σ3 axis is shown by the bar at each event location. The length of the bar corresponds to the plunge of the σ1 or σ3 axis. c Centroid locations of M > 7 earthquakes that occurred within the Pacific plate. The attached orange and blue bars denote the orientations of P- and T-axes. The length of the bar corresponds to the plunge of the P-axis or T-axis. The coseismic slip distribution of the Tohoku-Oki earthquake [3] is also shown by contours
