| Outline of Final Research Achievements |
This study tried to clarify geomorphological and geological characteristics of high relief mountain slopes. Results of this study are as follows; 1.Long term gravitational deformation is proceeding on "bell shaped mountain of high relief as higher as 500m in Japan. 2.The gravitational deformation is also proceeding just below break of slope inside the valley in the Himalayan mountains.Such shaped slopes are prone to collapse or slide when earthquakes or torrential rain occurs.
