Topographic map of Himebasti trench site, contours on the map are at 1 m interval based on a survey using Real-Time Kinematic Global Positioning System (RTK-GPS) in UTM 46N coordinates. An orange rectangle denotes the location of a N-S oriented trench (Top). RTK-GPS N-S (along AB) topographic profile across the fault scarp and projection of the Himebasti trench is shown in the bottom figure. The excavated pit has been projected over the ~ 6.8 m high fault scarp. Location of the pit is shown in Fig. 2, and field photograph is shown in Supplementary Fig. S3. Contour map and profile were prepared in Leica Geo Office v7.0 programme and artwork in Adobe Illustrator CS5 software.
