Newly Found Kentoyama Fault in the Northern Part of the Eastern Marginal Area of Fukui Plain, and Its Implications

摘要

The newly found Kentoyama fault runs through the northeastern part of Fukui plain, and its trend is nearly N-S. Based on the ob- servation of its fault outcrop, Kentoyama fault is composed of a set of three faults, and it deforms marine terrace deposits and sand dune deposits. The strike and dip of the fault sur- face are N7°-15° and 62°E-90°, respectively. The vertical slip rate of the Kentoyama fault is at least 0.04-0.12m/ky.
