ON THE RELATIONSHIP OF LANDSLIDES IN THE MOUNTAINOUS DISTRICT TO NATURE OF ROCKS, NATURAL FEATURES OF AREA AND DEPTH OF RAINFALL

About 500 samples were selected and investigated for the following factors: shape and area of sample, depth of landslide, depth of remaining sand and rock, earth volume of landslide, volume of remaining sand and rock, and the direction and slope angle of landslide. The mean value for each factor was calculated and the results are tabulated. The investigation reveals that the concentrated rainfall after a certain amount of precipitation causes the occurrence of numerous landslides and the number of landslides per unit area corresponds to the concentrated daily rainfall. Graphs are presented which illustrate the relationship, and equations are given which may be used to estimate the earth volume involved in the landslide.
