Through this research project, the scientific achievements are as follows: (1) Development of a compact data acquisition system with multi channels and solar battery for in-situ landslide observation of self-potential, (2) Development of self-potential tomography and noise reduction to visualize underground water condition, and (3) Installation of a practical base at Nishi-Ikawa, Tokushima, Japan to monitor self-potential at an in-situ slope. These achievements provide the new findings on hydrological-geotechnical-electromagnetic coupling for landslide processes and accumulation of the in-situ observation data. And they have been reported in 10 scientific papers (4 papers with review) and 34 scientific presentations at international and domestic meetings.

通过这一研究项目，取得的科学成果如下：(1)开发了用于现场滑坡自然电位观测的紧凑型多通道太阳能电池数据采集系统，(2)开发了自然电位层析成像和降噪技术，以可视化地下水状况，以及(3)在日本德岛西川县建立了一个实用基地，用于现场监测斜坡的自然电位。这些成果为滑坡过程的水文-岩土-电磁耦合和现场观测资料积累提供了新的发现。它们已在10篇科学论文(4篇有评论的论文)和34篇国际和国内会议的科学报告中发表。
