 Background of the project

Viet Nam has a rate of mountainous terrain up to 3/4 area of its territory, which has a dangerous cleavage terrain due to earth crust’s powerful tectonics. Moreover, it has complex geological structures with grave cleavages of soil layers. Besides, as Viet Nam’s geographical location is bordered by Pacific Ocean, it is influenced by the monsoon climate with the average annual rainfall from as much as 3,000-4,500mm/year. In this regards, it can be said that the phenomenon of landslides is one of the most serious natural disasters in Viet Nam. According to statistics, the annual volume of landslides on the roads after rainy season in Viet Nam amounts several hundred thousand cubic meters, which not only interrupt the arterial roads causing serious economic loss but also victimize around 30 people per year affecting communities in the mountainous areas.

This project is to contribute to geo-disaster reduction along main transport arteries and on residential areas through development of new landslide risk assessment technology and its application to forecast, monitoring and disaster preparedness of landslides in Viet Nam in close cooperation between Japanese and Vietnamese organizations concerned.
