Establishment of the prediction method for active-fault linkage and seismic motion taking into consideration for a fault process zone

以日本西南部地区为例，进行了以下研究：(1)描述断层过程带(如S波的波速、宽度和微结构)；(2)通过过程带特征提取在现代应力场下容易活动的潜在断层；(3)通过考虑断层过程带的伪三维断层运动模拟的改进，发展断层联系和地震运动的评价方法；(4)建立断裂带(或系统)的地震运动预测方法；(5)活动断层保存设施的维护和使用。

In Southwest Japan as a case study field, the followings are performed; (1) characterization of a fault process zone (e.g., s-wave velocity, width and microstructure), (2) extraction of a potential fault,, which moves easily under the modern stress field, by the process-zone characteristics, (3) development of evaluation methods for fault linkage and seismic motion by the modification of pseudo-3D fault-motion simulation taking into consideration for the fault process zone, (4) establishment of a seismic-motion prediction method for a fault zone (or system), and (5) maintenance and use of the preservation facility for the active fault.
