U.S. Geological Survey Open-File Report 03-095

Version 1.1
The map shows faults and folds in the state of Oregon 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.
