  • The first two columns indicate the subsurface bounds of the Oldham fault. The strike of the subsurface fault was N110° E, its length 79–95 km, and it slipped from 31 km to 6 km depth with mean slip 25 m. The coordinates of the surface expression of the 24 km-long Chedrang normal fault that slipped 11 m are listed in the six right-hand columns (England & Bilham 2015).
