概要
A shatter zone called “D-1” lies under the reactor building of Tsuruga Power Station Unit-2. In order to evaluate the activity of the D-1 shatter zone, the trench excavation survey etc. were carried out. The evaluation of activity clarifies the activity age of the fault based on the relation between shatter zones and the strata which covers it. The Quaternary deposited on the bed rock in which the D-1 shatter zone is distributed is classified into layer-No.1 to layer-No.9 based on the features. The results of the tephra analysis and the pollen analysis indicate that the lower part of layer-No.5 deposited about 130,000 years ago.
