Online_Linkage: https://doi.org/10.5066/P9M86S7D Description: Abstract: This portion of the data release provides the spatial thickness distribution of sandy deposits inferred to have been deposited at the Salmon River, OR by a circa 1700 CE tsunami. Data were collected by describing hand-operated gouge cores at 129 sites in 2017 and 2018, and supplemented by 114 core descriptions from 1987 (Nelson and others, 2004). Purpose: In the absence of detailed historical records of tsunami inundation along the Cascadia subduction zone, the geologic evidence of such events can be used to reconstruct the size and slip distribution of prehistoric earthquakes and tsunamis. The tsunami deposit thickness data presented in this portion of the data release can be used to infer the minimum inundation extent of a ca. 1700 CE tsunami and can be used to test models of earthquake rupture and tsunami sediment transport.

Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The locations of sites from 2017 and 2018 were determined using a Garmin etrex 30x handheld global satellite navigation system (GNSS) receiver capable of receiving wide area augmentation system (WAAS) signals. The manufacturer reported accuracy for horizontal positions is 3-5 m while receiving WAAS signals. Positional accuracy from the georeferenced 1987 cores is assumed to be worse than 5 m, due to errors in triangulation and digital georeferencing. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No formal positional accuracy tests were conducted, nor were they applicable for this dataset.

Walter in 1987 and published in Nelson and others, (2004) were georeferenced and reanalyzed to extract tsunami deposit thicknesses and the presence or absence of a buried soil horizon. Original core locations were determined through triangulation and annotated onto aerial photos. These photos were georeferenced in a geographic information system to determine the latitude and longitude for each site. Uncertainty in the 1987 core locations is unknown but assumed to be greater than the positional accuracy of GNSS-derived positions. The 1987 core descriptions note the depth of sandy layers and buried soil horizons that were originally interpreted to be from the 26 January, 1700 earthquake and tsunami. Source_Used_Citation_Abbreviation: Nelson and others, (2004) Process_Date: 20170601 Process_Step: Process_Description: The USGS collected cores from the Salmon River estuary in 2017 and 2018. Cores were described in the field and the presence or absence of a buried soil horizon was noted. Stratigraphy was described using the sediment classification schemes outlined in Troels-Smith (1955) and Nelson (2015). If present, depths and thicknesses of the sand layer immediately above the buried soil horizon were recorded. At the far inland extent of the sandy tsunami deposits, where the visually estimated bulk grain size of the deposit was a mixture of very fine sand and silt, only sandy lamina 1 mm or greater in thickness were identifiable as sandy deposits.
