The tritium content in both types of water is nearly the same as that of recent rain water. 4) The surface materials seem to have been moved sometimes in the past, and as a result of such occasional movement, the crack which coincides with slide surface would be originated in the talus deposits, as shown in Fig.1 of plate III and in Fig.17. 5) It is strongly suggested that the infiltration of large amount of water, which was supplied from rapid snow melting at unusual high temperature in that season, might increased the pore water pressure in the surface deposits to break the above-mentioned unstable state of slope, and the landslide was brought about in succession.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名",
