Continue the journey of surveying landslides in Lam Dong

13/09/2023
From August 18-22, 2023, within the framework of the unscheduled task "Survey and preliminary assessment of landslides in Lam Dong and Dak Nong and propose detailed plans" jointly organized by Vietnam Academy of Science and Technology and the Ministry of Science and Technology, the survey team continues its journey to the locations where incidents have occurred and with the high risk of incidents in the Ho Chi Minh City area. Bao Loc and along the Bao Loc pass route to Da Huoai district; Lam Ha District; Da Lat city.

The survey team collected information and conducted direct research at 7 specific points including: (1) Landslide of Bao Loc pass, next to Ba Co temple, Bao Loc bridge; (2) Bao Loc bypass route, National Highway 20; (3) Group 11 Residential Area, B'Lao Ward, Bao Loc City; (4) Landslides in Mang Lin residential area, Da Lat city and Da Sar kindergarten, Da Sar commune, Lac Duong district; (5) Collapse of residential area at National Highway 20 Anh Mai slope and Hoang Hoa Tham Alley, Ward 10, Da Lat City; (6) Lac Duong Urban Area; and (7) Landslide at Dong Thanh Reservoir, Lam Ha District. At each survey position, the delegation made appropriate assessments and recommendations to the Department of Science and Technology of Lam Dong province and reported to the Ministry of Science and Technology and Vietnam Academy of Science and Technology.

Regarding landslides in Lam Dong province, the survey team said that landslide accidents are still complicated, directly affecting the works. Therefore, it is necessary to review high and very high risk locations to assess the level of risk with a detailed ratio to more fully depict aspects that may affect landslides. In addition, provincial departments together with the Ministry of Science and Technology and Vietnam Academy of Science and Technology will further strengthen coordination and exchange to grasp the situation quickly. It is expected that after this survey trip, the delegation will summarize the assessment of the causes and mechanisms of formation of landslides and cracks in the survey areas and propose the next research and implementation plan for damage prevention and mitigation at the upcoming scientific conference on August 29.
