Derived data for "Calibration-range extrapolation and topographic constraints on source-based coseismic landslide hazard assessment: the 2024 Noto Peninsula earthquake, Japan

Author-generated derived-data package supporting the manuscript "Calibration-range extrapolation and topographic constraints on source-based coseismic landslide hazard assessment: the 2024 Noto Peninsula earthquake, Japan" (Chen, Yamada, Iida; submitted to Engineering Geology). The package contains: (i) the ring-by-ring strict polygon-only LL classification statistics (Table 2 of the manuscript); (ii) the slope-stratified buffer-width sensitivity of the LL-proximity FR (Table 3); (iii) the extended slope-stratified LL-proximity results and the strict polygon-only size analysis supporting Sections 4.2 and 5.1; (iv) the Noto slope-FR table (Section 4.1 / Fig. 3b), a 5-row author-generated CSV encoding the already-published Noto slope classes and FR values used in Eq. (5); (v) the nominal C22 and C22 × Noto-derived slope-FR ring predictions and 0–25 km RMSE / χ²-type metrics (Tables 5 and 6); (vi) the Phase 4C calibration-boundary sensitivity source ledger for the M0 vs M1 comparison (Tables 6 and 7); and (vii) M0 control checks and the Phase 4C validation write-up. Source data (GSI slope-failure/deposition inventory, GSI source-fault model, GSI 10 m DEM, NIED landslide-landform polygons, AIST/GSJ active-fault database, GSJ 1:200,000 Seamless Digital Geological Map, K-NET / KiK-net records) are publicly available from their original providers and are NOT redistributed here. All distance-based ring analyses, area calculations, and zonal-statistics summaries were performed in the JGD 2011 / Japan Plane Rectangular Coordinate System VII (EPSG:6675).
