SUMMARY

Characteristics of geohazards along the Đà River from Hòa Bình to Việt Trì related to neotectonic activities

Nguyễn Xuân Nam, Hạ Văn Hải, Hạ Quang Hưng

During recent years, many events of geological hazards have been occurring in the area extending from Hòa Bình to Việt Trì, such as: river bank scouring, cracking repeated in some places on the dyke, ground cracking and subsidence of land. The causes of these phenomena have not been found, therefore there haven’t got an appropriate remedy. On the basis of new research results, the authors touch upon endogenous geohazards (cracking, land subsidence, landslide, earthquake), exogenous geohazards (washing) in some places, such as Ông Tượng Hill (Hòa Bình Town), Phong Vân Commune (Ba Vì District), Tân Đức, Minh Đạo Communes (Việt Trì Town), to explain the relationship of these phenomena with the meridional fault activities.
