Average slope and curvature of landslides triggered by Hokkaido Eastern Iburi earthquake in 2019. Landslides were identified by Kita (2018): https://github.com/koukita/2018_09_06_atumathou. Slope angle and curvature were calculated with a 10 m DEM using ArcGIS software, made available to the public by Geospatial Information Authority of Japan (https://www.gsi.go.jp/kiban/index.html; index number: 6341-77, 6441-07, 6441-17, 6442-00, 6442-10). With the averaged curvature, each landslide was classified into four types: Cc, concave for profile and planform curvature, Ccpr, concave for profile and convex for planform curvature; Ccpl, concave for planform and convex for profile curvature, and Cv, convex for both curvatures. 'Planer' surface was not considered because of the data uncertainty. <br>
