Median grain size and grain size sorting of tsunami sand, dune sand, beach sand, and shallow marine sand. a Median grain size of sand shown by topographic type against grain size sorting. Results of shallow marine sand sampled off the coast of the valley were from Ohshima et al. (1986). b Median grain size shown by each topographic type against distance from the shoreline. c Grain size sorting shown by each topographic type against distance from the shoreline. Locations of the sampling site are shown in Fig. 1c. TS, tsunami sand layer; LM, lower main valley; UM, upper main valley; NV, north sub-valley; SV, south sub-valley; P, pond
