Summary of tsunami deposits and geomorphic evidence of great tsunami flooding in Corralero, Oaxaca. Supporting data in Supplementary Table S1 Supplementary information: Table S2 and Fig. S7. (a) Location map of study area and 3-D Lidar-based model (5 m resolution) of the bare surface at Corralero coastal plain, showing sand dunes, beach ridges and swales. (b) Cross section of pits, sand units correlated by stratigraphic and sediment characteristics, TSI shows inland extent of 1787 tsunami sand sheet. Microfossil, sediment elemental composition and 210Pb dates of pit 013 are shown in detail in Fig. 3. (c) Upper picture shows beach ridge and swale (people and a large tree standing for scale); lower pictures show pits at swales with evidence on sand units with abrupt basal contacts and soils beneath and above them. (d) Beach ridge breaches shown on satellite images (left and upper pictures) and on field-based photograph (lower picture), indicating tsunami breaching.
