Layer: Manual Parallel Displacement (ID:1)

Name: Manual Parallel Displacement

Display Field: Feature

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Displacements measurements are from high-resolution optical images of natural or cultural features right-laterally offset by the rupture. We prioritized high-quality measurements where distinct and sub-linear features (e.g., field or road edges) cross a simple (e.g., single-stranded) rupture trace at high angle. Displacements were measured by projecting features observable in the satellite images into the fault rupture and then measuring the displacement parallel to the rupture trend (e.g., Gold et al., 2015). Data fields include (1) Feature, the natural or cultural feature measured, (2) H_pref_m, preferred fault-parallel (right-lateral) displacement in meters, (3) H_min_m, minimum fault-parallel displacement in meters, and (4) H_max_m, maximum fault-parallel displacement in meters (e.g., DuRoss et al., 2024). Spatial coordinates (UTM_x and UTM_y) are for WGS 84 / UTM zone 47N (EPSG 32647). Measurement uncertainty (H_min_m to H_max_m for each point) is based on feature projections and for most measurements is at least twice the image pixel resolution (0.5 m). These measurements may not include additional centimeter-scale displacement along subparallel rupture branches not mappable at the pixel resolution of the satellite images.
