 note = {The Okimi landslide was divided into A valley (about 12.52 hectares) which included an active A block and B valley (11.35 hectares) which included comparatively steady B block. The amount of drain was measured in each valley and the chemical element included in the drain was analyzed. The amount of drain of A valley was three times B valley though the areas was almost the same as the A valley and the B valley. The outflow of all ions has increased in A valley when the amount of drain increases. There is no change at all ion outflow rate even if the drain increases in B valley. The groundwater which has a constant water quality always springs out in the B valley except miner ions like chloride ions. Increase of amount of drain is caused by adding of thawing water which contains negligible small amount of ions.},
