a Distribution of surface ruptures, previously mapped fault traces, and location of photographs (black dots) and the trench survey (yellow box) in the Uto segment and the southwestern section of the Futagawa segment of the Futagawa fault zone (Fig. 1c). b Surface rupture (white arrows) across a road and paddy field at Kitaamagi. c Surface rupture at Fukuhara showing dextral displacement of footpath in a paddy field (red half-arrows). d Left-stepping tension cracks showing a dextral slip in a wheat field at Togawa. e Surface rupture across a road at Shimotogawa with the north side downthrown by normal faulting with little lateral slip. f Surface ruptures on the north side of the Kiyama plain showing dextral offset of a road and paddy field. g Tensional cracks and mole track at Shimojin. The northwestern side of the wheat field was locally upthrown. h Dextral displacement at Tanaka along a surface rupture consistent with a fault trace exposed in previous trenching. i Surface rupture with sinistral and reverse offset at Shimojin, connecting two left-stepping en echelon dextral ruptures on the northern and southern edges of the Kiyama River alluvial plain. j Dextral displacement of a wheat field at Dozon, where the maximum slip of 220 cm was measured
