Summary To clarify role of hillslope scale on extension of dangerous area of snow avalanches, we examined relationship between relative height and horizontal level distance from initiation area to deposited area of snow avalanches. Also, we examined the role of slope gradients in erosion depth by snow avalanches using laser-profiler data.
