According Seed and JRA methods, when Taipei Basin has an earthquake stronger than the 5th degree (the surface acceleration Amax = 0.21g), and groundwater level is equal to or higher than - 5m, soil liquidation may occur from ground surface down to the depth of - 20m in areas of Songlung Road, Fuyuan Street, Nei- Hu High School, Ta - Yeh Road, Mingshuei Park, Mingshen East Road, and Shehchian Street. Similarly, when groundwater level rises to equal or higher than - 3.5m, soil liquidation may occur in depth between - 1m~- 8m in areas of Chungshan Girls' High School, Hwaling Street, Chende Elementary School.

中文摘要依 Seed 法与 JRA 法之分析研判显示，当台北盆地地区发生5级以上强震时(地表最大加速度a max=0.21g)：松隆路、抚远街、内湖高工、大业路、明水公园、民生东路以及实践街地区，在地下水位高於地表下5公尺至地表面时，从地表深度至地下20m 范围内均会有土壤液化现象；同样地，中山女中、华龄街、成德国小，当地下水位上升於地表下-3.5m 以上至地表面时，从地表下-1m 至-8m 处亦会有土让液化现象。

Computerized tomographyof cross-borehole electromagnetic is an advanced technology which successfully uses the principle of CT of medicine in geology. It reflects the physical parameter distribution in scenographic profile according the propagation of electromagnetic waves in lossy media and definite relation between physics and mathematics, finally gives the results by images.
