(a) Active fault map and hill-shaded DEM of Indo-China, highlighting the series of left-lateral strike-slip faults between the major right-lateral Saigon and Red River faults. Inset boxes indicate location of river offsets. Faults are from Taylor & Yin (2009). (b) Landsat false colour mosaic (RGB 752) of the Nam Ma and Mengxing Faults. The Nam Ma Fault has a current 11 km left-lateral displacement in the river, consistent with recent earthquake focal mechanisms, but overall has c. 31 km of offset in a dextral sense (Lacassin et al. 1998). (c) Landsat false colour mosaic (RGB 752) of the Wanding Fault with a current 10 km left-lateral offset of the Salween River, but overall a right-lateral offset of 33–54 km (Lacassin et al. 1998).
