Objectives: (5 lines maximum) The objective is to contribute to landslide disaster reduction along main transport arteries and on residential areas through study on effective application of new technology on forecast, monitoring and treatment of landslides in Vietnam and other areas in the Greater Mekong Sub-region in close cooperation with Japanese universities and also ICL. The following targets are expected: a) Development of Landslide risk assessment technology suitable for the targeted areas in Vietnam. b) Capacity Development for research on landslide risk identification and hazard mapping. c) Social application over the regions. 6. Study Area: (2 lines maximum) Viet Nam, Japan, Countries in the Greater Mekong Sub-region (e.g. Laos and Myanmar)

2 7. Project Duration (1 line maximum) 5 years from March 2012 to March Report 1) Progress in the project: (30 lines maximum) Total 60 (man x times) Japanese researchers visited Vietnam and investigated landslides in Ho Chie Minh Route, Hai van Station, National Route No.6 and visited ITST in Hanoi in The Japanese experts are landslide mapping (Headed by Miyagi), landslide monitoring (Headed by Ochiai) and landslide testing (Headed by Sassa). We selected a large-scale landslide including the Hai Van Station which is the mid-station of Vietnam National Railway between the North and South Vietnam as the pilot study site. We installed an extensometer in 2013 and prepared to install 19 long span extensometer, one total station with 30 prism, and 3 static GPS (GNSS) and two real time kinematic GPS and three drillings on the landslide in The installation and drilling was initiated in the end of Vietnam engineers are invited to Japan by this project in 2012, 2013 and They have entered in Kyoto University, Tohoku Gakuin University, Shimane University, and Shizuoka university and studying landslides as master or doctor course students. In addition to these invitation, 4 man/times were invited for 3 weeks in Japan. One student took master and returned to Vietnam. Other six students will take Master or Doctor Degrees in 2015 and As reported in IPL-157, the group has developed a new high stress ring shear apparatus (ICL-2) to simulate the initiation and motion of megaslides with more than 100 m depth in Based on the developed apparatus and training, a new apparatus having the same capacity, but suitable to be maintained and used in Vietnam has been developed in It will be further checked in January to March in 2015 and donated in June 2015 after final improvement and confirmation of use by Vietnamese trainees. This apparatus was firstly applied to samples taken from 1792 Unzen Mayuyama megaslide (volume is 3.4 x 10 8 m3, Maximum depth is 400 m) triggered by an earthquake in Kyusyu island in Japan. The test result and performance was very satisfactory. Then, the apparatus was applied to the Heivan station Landslide in Vietnam using sample taken from the ground of Hai van Station slope. 2) Planned future activities or Statement of completion of the Project (15 lines maximum) The developed high stress ring shear apparatus will be continued to be applied in a mega-slide at Hai van Station of Vietnam National Railway. Drilling will be in progress. The sample is expected to be taken from drill holes. The sliding surface depth will be estimated from the drilling and monitoring. Using those data and the test of ring shear apparatus and the computer simulation, landslide risk of this landslides will be assessed. In 2015, we will install 19 long span extensometers, one total station with 30 prism, and 3 static GPS (GNSS) and two real time kinematic GPS (GNSS) and three drillings at one site in the landslide and

3 installed the inclinometers and pore pressure sensors in three drilled holes. All necessary procedures were completed in We organized a SATREPS session in the Third World Landslide Forum on 2-6 June 2014 in Beijing. A SATREPS Workshop as the activity of this project was organized on 8 July to 1 August 2014 in Hanoi. In this workshop, all seven Vietnamese students and all Japanese project members had oral presentation of their research. 2) Beneficiaries of Project for Science, Education and/or Society (15 lines maximum) The subjects directly benefiting from the project's achievements include: In Vietnam: people in 10 provinces frequently affected and the impact of the phenomenon of landslides and a team of young engineers in the research institutes, universities and in technical management agencies in local conditions better awareness in order to prevent landslides as housing, farming and irrigation in mountainous conditions and applying appropriate technology to actively prevent, mitigate consequences natural disasters caused by landslides. In Laos and Myanmar: people in some mountainous locals and a division engineers in the agency and management consulting. Results can be disseminated to other developing countries in the region and the world to study and apply. 3) Results: (15 line maximum, e.g. publications) 1.
