This raster GIS dataset contains values ranging from 0 to greater than 500 cm depicting the dry landslide permanent ground deformation for the Oregon Seismic Hazard Database.
The dry landslide permanent ground deformation in this study is useful for loss estimations in HAZUS-MH, and other similar regional hazard assessments from ground velocity faced at a given location. This ensemble of 30 megathrust rupture scenarios calculated with a range of parameters to encompass the likely variability of actual Cascadia events model provides a better representation of the total hazard faced at a given location.

Care was taken to limit categorical attribute errors. Attribute accuracy of the dataset was visually inspected to identify potential anomalies, which were investigated to ensure they were consistent with the underlying data.
Topological checks were conducted to verify there were no gaps or overlaps between polygons before conversion to 30m resolution raster. Dataset QA-QC was carried out, range of values was verified to be correct. Data were visually reviewed to identify potential anomalies, which were investigated to ensure they were consistent with the underlying data.
The dry landslide permanent ground deformation includes information for the state of Oregon. No attempt was made to test and compare different methods or data sources, which was beyond the scope of this project.
The geologic unit polygons have variable positional accuracies due to variable scales in compilations. However newest geologic maps were digitized on a lidar base at a 1:8000 scale. As a result the data set has a highly variable horizontal positional accuracy throughout the state of Oregon. Refer to the original source data for positional accuracy.

Data was derived from 4 source types. A geologic map compilation (OGDC-7), updated with recently prepared or published geologic maps, older seismic hazard studies using 3D data, recent geohazard studies that are published or in preparation, and landslide polygon data from SLIDO-4.2. For the OGDC and SLIDO 4.2 data, values were assigned based on a geologic unit, see report for further details. Other geohazard studies provided data that was directly useable. The various layers were stamped together in a specific order, described in the report. The resulting polygon data set was converted to a 30m raster following topology review. Final datasets where then converted to 98.4ft rasters due to the Oregon statewide projection standard unit being feet.
