|The map shows faults and folds in the state of Washington that exhibit
evidence of Quaternary deformation, and includes data on timing of most
recent movement, sense of movement, slip rate, and continuity of surface
expression. The primary purpose of this compilation is for use in earthquake-hazard
evaluations. Paleoseismic studies, which evaluate the history of surface
faulting or deformation along structures with evidence of Quaternary movement,
provide a long-term perspective that augments the short historic records
of seismicity in many regions. Published or publicly available data are
the primary sources of data used to compile this report.

|A catalog of referenced data, which includes a variety of geographic,
geologic, and paleoseismic parameters for the faults and folds shown on this
map, is available in the “Quaternary
fault and fold database of the United States” (http://qfaults.cr.usgs.gov/). The pamphlet of this
Open-File Report (03-428) discusses relations of this Washington State map
to the Quaternary fault and fold database of the United States.
