Includes stratigraphy, diatom assemblages and radiocarbon dates from fossil cores and diatom assemblages from modern tidal marsh samples. Data were collected to provide evidence for multiple great earthquakes in south-central Chile, and enable the reconstruction of vertical land-level changes associated with these earthquakes. Data are from tidal marsh sites within the 1960 earthquake rupture area along the Chilean subduction zone (37.5 - 46 degrees South).

We employed transects of cores to assess lateral continuity of stratigraphy. In order to obtain a training set of modern diatom assemblages, we sampled at low tide the top ~1 cm of sediment at regular vertical intervals along transects perpendicular to the direction of tidal inundation. Samples collected January 2013 and 2014. Samples were analysed for diatoms and plant macrofossils picked for radiocarbon dating. Radiocarbon dates were provided by the NERC Radiocarbon Facility. A diatom-based transfer function was developed in C2.
