Chaihuin diatom, radiocarbon, sedimentology, stratigraphy data

(i) Diatom percentage data and (ii) radiocarbon dates from three tidal marsh cores from Chaihuín, south-central Chile. Cores span ~1400 cal yr BP to present, diatom analysis focussed around three abrupt contacts interpreted to represent three great tsunamigenic earthquakes. <br><br>(iii) Stratigraphy data from tidal marsh cores from Chaihuín, south-central Chile, including core locations and depths/thicknesses of tsunami sands. As well as sedimentology of sand sheets, including grain size, sorting and clastic composition data.<br><br>Data and full analysis presented in a paper by Hocking et al. in Communications Earth and Environment.
