| Research Abstract |
The Sabae fault, presumed from geomorphic characteristics, is a reverse active fault that extends NS for 18km long along the western flank of the Sabae plateau in the seismic gap around the Seibu-basin, Fukui Prefecture, central Japan. In this research, we clarified the existence of this fault system, and two faulting events based on borehole drillings across the fault. The latest faulting event occurred after A. D. 500 and the penultimate one was between B. C. 2400 and B. C. 1800.
