| Research Abstract |
The age of formation of oldest terrace along Imo River is detected to be younger than 16,500 year ago, because the terrace is not covered with Asama Kusatsu tephra. The growth rate of the Komatsugura anticline is estimated 0.8-1.9 x10^<-6>/year by terrace formation age. This value is same order as the growth rate of active fold in Nishiyama Hills and Ojiya district. In the Nagano Niigata border Earthquake, the foundation disaster was concentrating in the hanging wall side of a reversed fault, in the form governed by distribution of geology, geological structure, and active fault, etc. And it has pointed out a possibility that the Matsunoyama anticline grew in connection with this earthquake.
