THE ANALYSIS OF SNOW MELT LANDSLIDE IN FUKUI PREFECTURE

众所周知，滑坡的成因是滑坡发生地的地形和地质特征。此外，北陆地区冬季和雨季的融雪也导致了许多滑坡的发生。作者之一报道说，新泻县融雪期的滑坡主要取决于融雪期。本研究调查了福井县滑坡发生频率与最大融雪期的关系。结果表明，新泻县的数据也得到了相同的关系。但是，福井县的融雪期相对较短，因此该县位于降雪区的南部。因此，本研究以最近发生的那志贺平滑坡为例，探讨福井县融雪型滑坡的特征。

It was well known that the causes of landslides are topographies and geological features of the landslide places. Furthermore, in Hokuriku district, many landslides occurred by snowmelt in winter and rain.The one of authors reported that the landslide in the snowmelt period in Niigata prefecture depends mainly on the snowmelt period.In the present study, the relation between the frequency of landslide in Fukui prefecture and the maximum snowmelt period is investigated. As the result, same relations by data of Niigata prefecture was obtained. But, snowmelt period at Fukui prefecture is short comparatively so that this prefecture is located in southern part of snowfall zone. Therefore, characteristics of snowmelt landslide in Fukui prefecture was investigated by the data of Nashigadaira landslide occurred recently.
