The phenomena of collapse and erosion on the granitic area were examined using the data of collapse due to the disaster in Misugi Village, Mie Pref., in 1982 and the data of erosion on the site of collapse in the Mie University Forest. The summary of the results is shown below.1) An cccurrence of collapse is strongly affected by the factors concerned with a gradient of slope and rainfall intensity.2) The depth of erosion during a certain period tends to get deeper as the maximum daily rainfall in this period gets larger, but in the case of daily rainfall of a few millimeters, an accumulation of soil of weathered rock is observed.3) The process is guessed that the topography of a slope is changing by the superposition of a cycle of erosion according to frequency of rainfalls of various scales and a cycle of erosion with a period of a year.
