Description: Washington has dozens of faults and fault zones with geologic evidence of movement in the Quaternary time period, of which many pose a significant hazard for Washington communities. This dataset contains geologically well-supported interpretations of Quaternary fault location, age and other parameters important for assessing seismic hazard. Another term commonly used for faults with movement during the Quaternary is "active". For the Washington Geological Survey, "active" means that a fault has evidence for movement within the Holocene time period (since about 12,000 years ago). It may also mean that small earthquakes have been documented on the fault. We include active faults in this database as well as other faults that have evidence for movement within the Quaternary time period (last 2.58 million years) or suspected movement in the Quaternary (also called class B), because they all have the potential to create damaging earthquakes sometime in the future within a timeframe that matters to humans. For most faults in Washington, there is not enough evidence of past earthquake activity to forecast the timing of future events. Throughout scientific history in Washington state, different interpretations of Quaternary faults have resulted from different mapping methods and scales of investigation. Dataset users will benefit from a full investigation of sources cited, reading other past work, and developing an understanding of the breadth of study types for any particular fault of interest. For geologic mapping, tectonic studies, and other scientific investigations, this database is best used for understanding the orientation of, connectivity between, and deformation along Washington fault networks in the present. For earthquake hazards characterization, this database is best used in reconnaisance-scale investigations, to identify regions closer or farther away from active faults in a qualitative sense, or in probabilistic seismic hazard analysis studies (PSHA) that consider the hazards that faults pose for a given area in a probabilistic sense. The WGS does not advise uses of this database that aim to quantify distance of a location of interest to a particular fault or that rely on high precision fault placement with respect to specific properties.
