Currently,
the Division of Geology in the North Central Coast has explored the project
"Investigate and evaluate environmental impact due to geohazards along the
Highway 7- Cả river, Nghệ An province and the Highway 8 - Ngàn Phố
river, Hà Tĩnh province". Results of the investigation show that the
research area have geohazards in different locations including more than 549
landslides, 61 flash floods and 186
riverbank erosion, in which some large locations caused enormous damage to the
community. The geohazards are mainly due to complex terrain and geology
structure, human activities, as well as Cả and Rào Nậy River
faults. To prevent and mitigate damage of these geohazards, some measures must
be carried out such as to raise awareness of citizens in prevention of
geological disasters, and to adjust distribution of population and building infrastructure appropriate to geological
features.
