To define the role of ancient geological structures and Neotectonic structures and tectonic movements in land-fissure and landslide forming along Highway N6 and to propose their mitigation and remedation measures.

• - Về khoa học: Xây dựng được sơ đồ phân vùng dự báo nguy cơ nứt-trượt, lở đất dọc tuyến QL 6, theo các yếu tố nguy cơ cấu trúc địa chất và chuyển động Tân kiến tạo.
• - Về ứng dụng: Kết quả của đề tài có thể ứng dụng trong công tác quản lý và phòng chống thiên tai vùng Tây Bắc Việt Nam, đặc biệt là quản lý và phòng chống tai biến nứt-trượt, lở đất dọc QL 6.

• Theorerical results: Provide map-Schemee of land-fissure and lanslide risk zoning and prediction based on geological structural and Neotectonic movement risk factors.
• Applied results: Results of the research can be applied in the natural hazard management and prevention in Northwestern Vietnam, specially in management and prevention of land-fissures and landslides along Highway N6.

It’s first time the zoning and prediction of land-fissure and lanslide risk along highway N6 based on geological structural and Neotectonic movement risk factors have been caried out
