The coastal areas of Vietnam are in danger of earthquakes and tsunamis

Above are the latest research results of the Institute of Geophysics, Institute of Geology and Institute of Geology - Marine geophysics.

Accordingly, earthquake hazard is unevenly distributed across the entire coastal strip and continental shelf of Vietnam. The northern coastal strip from Quang Ninh to Ha Tinh has the highest earthquake hazard, forming a level 7 tremor zone.

Next is the North Central region, including the provinces of Quang Binh, Quang Tri, Thua Thien Hue, Da Nang, Quang Nam and the range from Quang Binh to Khanh Hoa in the shock zone from level 7 to level 8. At some The tremors in Ninh Thuan, Binh Thuan and Ba Ria - Vung Tau provinces are assessed up to level 8.

Besides, dangerous tsunami maps also show that the risk of tsunamis affecting Central coastal areas, North Central and South Central is quite clear, with repeat cycles of 475 and 950 years. . Tsunami elevation in the Central Coast region ranges from 3 - 4m in the 475 year cycle and 5-6m in the 950 year cycle. In the Hoang Sa and Truong Sa archipelagos, the North and South regions are between 2-3m in the 475 year cycle and 3 - 4m in the 950 year cycle.

According to Prof. Dr. Bui Cong Que - Institute of Geophysics, areas of earthquakes and tsunamis that are capable of causing earthquakes and tsunamis that directly affect the coastal of Vietnam include Manila submerged zone, Northern source area. The South China Sea and the East Vietnamese slope fault zone on the continental shelf and coastal area of ​​Central Vietnam.
