Bowman, J. D.; Czajkowski, J. L., 2019, Washington State seismogenic features database--GIS data: Washington Geological Survey Digital Data Series 1, version 5.0, previously released April 2016.
<DIV STYLE="text-align:Left;"><DIV><P><SPAN>These data contain points representing all known trenches and excavations along known or suspected active faults in the state of Washington.</SPAN></P></DIV></DIV>
This dataset was compiled as part of the Data Preservation Program of the Washington Geological Survey, the aim of which is to organize and preserve geologic data in a digital format and to make it easier for the public to obtain. The creation of this trench dataset was prompted by the need for up-to-date and spatially accurate reporting of paleo-seismic investigations of known or suspected faults of Quaternary age in WA State.

The dataset was frequently checked for accuracy, proper formatting, and consistency following multiple stages of completion, by visually and statistically checking data tables. Consistent practices were used to generate points.
All possible effort was made to include all of the known trench locations located on suspected Quaternary-age faults.

The trench dataset was generated by performing a detailed study of existing literature, georeferencing source maps, digitizing trench locations, and then generating attributes for points, such as trench name, corresponding fault trace (if applicable), whether or not the trench contained evidence for Quaternary deformation and other ancillary information. Version History: Version 5.0 (February 2018): New historical earthquake damage feature class added to the geodatabase. Version 4.1 (Febuary 2016): URL field was added to link to trench log publications and added new records. Version 2.1 (June, 2011): The dataset was edited for content accuracy. Version 2.0 (June, 2010): This dataset was migrated from a shapefile to a geodatabase. Feature class names and attribute names were changed, and metadata for the entire dataset was updated. Version 1.0 (2008): Original data in shapefile format.
