a, b Single right-lateral offset of the Semangko River where it crosses the main active trace of the West Semangko Fault, south of Suoh (location is marked at Fig. 3). Channel incision at this site postdates eruption of the Ranau Tuff. The high-resolution digital terrain is developed from local topographic contour map for the Hydroelectric plan constructions. c Restoration of old topography before 230 m right-lateral movement. Slip rate is 6.8 ± 1.8 mm/year taking into account the width of the river valley (~60 m) as the uncertainty of measurement
