Original caption of the image: "Fig. 8. Seawall damage observed during the 2011 EEFIT Mission: (a) damage to seawall and quay at Minamisanriku; (b) close-up of seawall block at Minamisanriku showing no interlinkages; (c) recovery work on the seawall at Miyako Bay; and (d) remaining seawall buttress at Tarō."

Original context of the image: "Seawall failures of both gravity seawalls and compacted sand core structures were also observed (Fig. 8). Failure mechanisms of the Tarō seawall included the removal of rear slope protection blocks due to the tsunami overflow, the collapse of the crest parapet due to impulsive fluid forces, the collapse of the front protection blocks due to draw-down and there was also evidence of shear failure between blocks [29]."
