Description:
This geodatabase contains seven point, line, and polygon feature classes pertaining to seismogenic features in Washington State, including: 1) active faults (faults with demonstrable Quaternary-age activity), 2) active folds (folds with demonstrable Quaternary-age activity), 3) paleo-seismic trench locations (excavations made for use in studying and documenting potentially active faults), 4) PNSN earthquakes (earthquake catalog data obtained from the Pacific Northwest Seismic Network greater than 1 M and <25 km in depth), 5) relocated earthquakes (a subset of the PNSN earthquakes of accurately relocated earthquake hypocenters), and 6) relocation processing areas (areas used to group clusters of earthquakes during hypocenter relocation processes), 7) Historical earthquake damage with related table of damage photos.
