Fukui prefecture is located most southern part as a snowfall zone in Japan. Accordingly, after a snowfall, melting snow begins immediately. As the results, in Hokuriku district, many landslides occurred by snowmelt in every March and April. The one of researcher reported that the landslide in the snowmelt period in Niigata prefecture depends mainly on the snowmelt period. Presently, characteristics of snowmelt landslide in Fukui prefecture was investigated by the data of Nashigadaira landslide occurred recently. In particular, relation between snowfall and water level under the ground was investigated. In addition, relation of slant of the ground and water level under the ground is also examined. Furthermore, landslide places were observed by using image of a satellite. By these results, mechanism of landslide occurrence was reported.

福井县位于日本最南部的降雪区。因此，在一场降雪之后，积雪立即融化。因此，在北区，每年3、4月份都会发生多起融雪山体滑坡事件。一位研究人员报告说，新泻县融雪期的滑坡主要取决于融雪期。目前，福井县融雪滑坡的特点是利用新近发生的Nashigadaira滑坡的资料进行调查。特别研究了降雪量与地下水位的关系。此外，还研究了地面倾角与地下水位的关系。此外，还利用卫星图像对滑坡地点进行了观测。根据这些结果，对滑坡的发生机理进行了探讨。
