Distribution of the late Quaternary average vertical slip rate of the Morimoto-Togashi fault

Abstract

The Morimoto-Togashi fault is a reverse fault extending for 25km along the eastern margin of the Kanazawa Plain. The Morimoto-Togashi fault is characterized by fault scarps several meters high on late Quaternary fluvial terraces and the formative age of fluvial terraces were estimated by Nakamura et al (2003). We measured the vertical displacement of fluvial terraces across the Morimoto-Togashi fault and estimated the distributions of vertical average slip rates. Vertical average slip rates for the Morimoto-Togasi fault are 0.13-0.35 mm/yr (northern part), are 0.05-0.70 mm/yr (central part), and are 0.24-0.40 mm/yr (southern part), respectively. This implies that the peak of vertical average slip rate exist the Kanazawa City area and the Morimoto-Togasi fault does not move with the Sekidosann fault.
