Mud- to cobble-sized sediments formed layered deposits that covered the lowland where paddy fields had been. These layered deposits were remarkably thick (> 0.5–1.0 m) near the beach, where they were composed mainly of gravels, and they generally thinned and fined inland to sand and mud deposits a few centimeters thick. Separate from the layered deposits, many boulders, consisting of fragments of the tsunami barrier and other structures, wave-dissipating blocks, and volcanic rocks, were found on the lowland, mainly in three clusters. Boulder size decreased abruptly about 750 m inland from the shoreline, where the thickness and grain size of the layered deposits also showed a sharp decrease. These findings suggest that a sudden deceleration of the wave flow velocity, constrained by the local topography, caused rapid deposition of both the layered deposits and boulders there. Interestingly, the boulders were deposited on top of the layered deposit, not buried within it. This finding suggests that sand and gravel were transported in the bore front of the first wave and deposited before the arrival of the boulders. Seaward-extending scours around large boulders showed that the boulders were not moved by the backwash flow, although the backwash eroded the layered deposits to some extent. The stratigraphic relationship between the layered deposits and boulders therefore suggests that both were probably deposited by the first wave."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381418519144359042","@type":"Researcher","foaf:name":[{"@value":"Masaki
