The Iwate-ken Nairiku-hokubu earthquake of September 3,1998, caused surface rupture on the Shinozaki fault, at Shizukuishi, Iwate Prefecture, northeast Japan. The fault, dipping to the west and northwest, was traced about 800 m along strike. Reverse slip produced vertical displacement of 0.25-0.32 m. Landslides and building damage occurred in the northern and northwestern area of the fault. The southern part of the fault dovetails with the northern part of the previously mapped Nishine fault
