Summary

This release is an update to the online "Quaternary fault and fold database" for Washington State. The online database was last updated for Washington in 2014 – this 2020 update includes newly identified and modified traces and geometries for on-shore faults gleaned from new peer-reviewed studies and mapping of active faults within the state of Washington. These data contain lines representing the location of faults with known or suspected Quaternary (<1,600,000 yrs) activity in the state of Washington. This data was compiled in conjunction with the Washington State Geological Survey. Faults are attributed following the Quaternary fault and fold database attributes, including information such as age, slip sense, dip direction, class, [...]

Purpose

The data were collected as part of an effort to updated and document potential earthquake sources for seismic hazard assessment in the National Seismic Hazard Maps. The aim of the Quaternary fault and fold database is both to organize and preserve various types of geologic data in a digital format and to make it easier for the public to obtain the data. The creation of this dataset was prompted by the need for up-to-date and positionally accurate reporting of known or suspected faults of Quaternary age resulting from newly published peer-reviewed studies in Washington State.
