a Distribution of surface ruptures (red lines), previously mapped active fault traces (blue lines), and locations of photographs (solid circles) and the trench site (yellow box) along the Takano-Shirahata segment of the Hinagu fault zone (Fig. 1c). b Cultural features including rows of wheat displaced dextrally (red half-arrows) at Kamitakano along the rupture (white arrows). c Edge of a road displaced dextrally. d Postseismic activity shown by a crack in a paved road at Takaki. The open crack, filled with asphalt after the mainshock, opened further by the time the photograph was taken on April 28. e Array of left-stepping tension cracks produced by dextral faulting in the alluvial plain at Takaki, as seen on April 16 after the mainshock. f Aerial photographs of Takaki (Geospatial Information Authority of Japan 2016a, b) on April 15 (left) and April 20 (right). No surface rupture was apparent on April 15, whereas a distinct surface rupture displacing rice paddies and footpaths was discernible on April 20. The black arrow shows the location of E. g Dextral offset of wheel tracks by 75 cm on a farm road in Takaki
