Data compiled from stratigraphic and tree-ring studies of late Holocene earthquakes and tsunamis at Copalis River, Grays Harbor, Willapa Bay, and Columbia River, Washington and Oregon
This dataset consists of tabular information from coastal studies of earthquake and tsunami history along a central part of the Cascadia Subduction Zone. The study area encompasses four estuaries along the Pacific coast of southern Washington and northernmost Oregon. Nearly all the field work took place between 1986 and 1998. Data tables, 18 in all, archive mostly georeferenced information about stratigraphy, radiocarbon ages, and trees dead and living. Some of this data was interpreted in reports published between 1987 and 2005, but most of it was previously unavailable. An accompanying guide, with hyperlinks to the data tables, explains the data tables more thoroughly than does the metadata. Contributors include five dozen participants in the field work. Brian Atwater compiled the tables and guide in 2019 and 2020.
