Abstract
Landslide blocks can be classified into first, second, and third levels. Not only whole blocks but also second and third level blocks have unique fractal dimensions. The fractal dimension is reversely proportional to the logarithm of standard deviation of the blocks' size. Numerical analysis revealed that fractal dimension correlates to the geometry of the landslide, discontinuities of the base rock, and activity of the landslide. Fractal dimension is independent of the size of the landslide, angle of slide surface and slope, and geology of the base rock. The fractal character of landslide block distribution can be explained by self-similar geometry, the unique fractal dimension made by combining second and third level blocks, and fractal erosional process. Fractal character of landslide block distribution can be used to identify potential landslides and can be used as a numerical index to describe landslides including their level of activity.
