Fig. 5.From: Detailed stress fields in the focal region of the 2011 off the Pacific coast of Tohoku Earthquake—Implication for the distribution of moment release—Results of stress tensor inversion (top) and K-means clustering (bottom) in the shallower part near the trench axis shown in Fig. 2. The top panel is obtained in the same way as in Fig. 4. In K-means clustering, we assumed two clusters for stress states. The large circle and triangle show the two representative stress states.Back to article page
