The survey team work with the Department of Science and Technology of Lam Dong province
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.
