The 2004 Niigata Chuetsu earthquake (Mw6.6) occurred with the inland active fold and reversed fault belt. This research tried quantification of the amount of inclination, in order to understand the style of the crustal movement. The geological data of about 2000 points, the geological unit, strike and the inclination, were inputted into GIS, and the frequency of the distribution over the geological unit was created. In addition, we interpreted the fluvial terrace surface and the alluvial surface from the air photographs, the classification map is created. These geologic data and geographical feature data piled-up on GIS serve as a displacement standard of an activity of the active fault or a long term of the crustal movement.

2004年新泻中越地震（Mw6.6）是伴随着内陆活动褶皱和反转断裂带而发生的。本研究尝试量化倾斜量，以了解地壳运动的风格。将约2000个点的地质数据、地质单元、走向和倾斜度输入GIS，并创建地质单元上的分布频率。此外，我们还根据航空照片解释了河流阶地表面和冲积表面，并创建了分类图。这些堆积在GIS上的地质数据和地理特征数据，可以作为活动断层活动或地壳长期运动的位移标准。
