Forecast for 45 source regions of earthquakes and 09 source zones of tsunami in the East Vietnam Sea by 2022?
Expected earthquake disaster can happen under Decision 645 / QD-TTg in Vietnam?
In sub-section 1, Section II, the Plan issued together with Decision 645 / QD-TTg in 2022 on the national plan to respond to earthquakes and tsunamis, promulgated by the Prime Minister on expected dynamic disasters. The possible land in Vietnam is as follows:
On the territory and continental shelf of Vietnam, there are faulty systems that operate and are called by the names of major rivers such as Red River, Chay River, Ma River, Da River, Ca River. The fault system runs in the Northwest - Southeast in the Northern territory and the Kinh Tuyen 1099 fault system runs along the Central Coast and South Central Coast, etc. These faults create 45 source regions. earthquakes, including 09 tsunami sources in the East Sea.
Levels of natural disaster risk caused by earthquakes in different areas are determined according to the maximum earthquake scenario, specifically as follows:
- Northwest region: Earthquake scenario of magnitude M = 7.2 occurring on the Son La fault at coordinates, latitude 103.44, latitude 21.64) causes natural disaster risk level 4-5 in Truot in some areas of Dien Bien and Son La provinces; Level 3 - 4 in some areas in Lai Chau, Yen Bai, Lao Cai and level 1-3 in Tuyen Quang, Ha Giang and Phu Tho province
- Northeast region: Earthquake scenario of magnitude M 55 occurs on the Cao Bang - Tien Yen fault at coordinates (Longitude 106 54, Latitude 22 16) causing level 4 natural disaster risk - 5 in some areas of Lang Son province, level 3 in some areas of Cao Bang, Bac Kan and level I in some areas of Thai Nguyen and Bac Giang
- Red River Delta region: Earthquake scenario of magnitude M - 63 occurring on live fault Run at coordinates (Longitude 106.07, Latitude 20.65) causes the level of genius risk. 4 -5 in Ha Nam, Nam Dinh, Hung Yen, Thai Binh and Hanoi. Level 1 - 2 in the area of Bac Ninh, Ninh Binh, Hai Duong, Hai Phong and Vinh Phuc;
- North Central region: Earthquake scenario of magnitude M = 6.5 occurring on fault of life C at coordinates (Longitude 105 583, Latitude 18,906, in Dien Chau district, Nghe An) causes level level 4 - 5 natural disaster risk in Nghe An province, level 3 - 4 in Ha Tinh province; Level 1 - 3 in Thanh Hoa province and level 1 in Quang Binh, Quang Tri and Thua Thien Hue provinces,
- South Central region and Central Highlands: Earthquake scenario of magnitude M = 5.8 occurs on fracture causing Ba To - Cung Son in La degree (Capital 108.74, Latitude 13 99] thin and risky level level 4 -5 natural disaster risk in some areas of Binh Dinh and Gia Lai provinces (epicenter area) and level I in the surrounding areas,
- Southern region: Scenario of maximum earthquake MH 3.0 occurred on the expensive causing Hau river at longitude (Longitude 105.81, Latitude 10.54) Get the level of risk | level 4 natural disasters in some areas in Vinh Long and Can Tho provinces (in the heartland); Level 1 - 2 in the vicinity of Vinh Long, Can Tho, Hau Giang, Tra Vinh and neighboring areas.
Is a tsunami disaster expected under Decision 645 / QD-TTg in Vietnam?
Under the provisions of sub-section 3, Section II, the Plan issued together with Decision 645 / QD-TTg in 2022 on the National Plan to respond to earthquakes and tsunamis, promulgated by the Prime Minister. Tsunami disasters can occur as follows:
In the East Sea and surrounding areas, there are 09 tsunami source areas that are likely to affect Vietnam, including: Fracture source zone of Meridian 109, North East Sea, Pa la oan-Borneo, Manila / Phi deep sea trough - Cyprus, Taiwan Sea, Sulu Sea / Philippines, Selebes Sea / Philippines, Ban the North Sea and the South China Sea / Indonesia. The tsunami hazard to the coastal areas of Vietnam is assessed by the quantity of the maximum wave height caused by the tsunami and the time of tsunami propagation from source to coast. In the tsunami source zones in the South China Sea and surrounding areas, the Manila / Philippines Deep Sea Plate source area
The battery is considered the most dangerous source for Vietnam. Monkey with earthquake with maximum magnitude of up to M = 93 in this area is dangerous
The rare occurrence of tsunamis affecting the entire coastal strip of Vietnam is reflected in the level of tsunami risk, specifically as follows:
Level 4 natural disaster risk (corresponding to wave heights from 8 m to 16 m): coastal area of Thua Thien Hue province, Da Nang city, Quang Nam province, province
Quang Ngai, Phu Yen Province, Khanh Hoa Province and Binh Thuan Province. The life time for the god to spread and attack ashore ranges from 2.0 hours to 4.5 hours, deep inland can be up to 2-3 km;
Level 3 natural disaster risk (corresponding to wave heights from 4 m to 8 m): coastal area of Hai Phong city, Nam Dinh province, Thanh Hoa province, Nghe province
An, Ha Tinh province, Quang Binh province, Quang Tri province, Binh Dinh province, Ninh Thuan province, Ba Ria - Vung Tau province, Ben Tre province, Bac Lieu province and Ca Mau province, Life time god spread and attacked ashore from 3.0 hours to 9.0 hours inland may reach hundreds of meters;
Level 2 natural disaster risk (corresponding to wave heights from 2 m to 4 m): Quang Ninh province, Thai Binh province, Ho Chi Minh city, Tra Vinh province and province
Soc Trang The life time when the gods spread and attacked ashore was about 82 hours and 149 hours, inland could reach hundreds of meters,
Level 1 natural disaster risk (corresponding to the wave altitude below 2 m): Tinh Ninh Binh and Kien Giang province. The time when the tsunami spread and hit the shore was about 8 to 15 hours. Tsunamis caused local flooding at some points.
Thus, to your question, the specific goal of the National plan to respond to earthquakes and tsunamis is to create a unity in awareness and action of the agency, organization and people, ensure close coordination with ministries, central agencies and localities in implementing solutions to respond to and overcome consequences of earthquakes and tsunamis; perfecting the national system of plans to respond to major incidents, natural disasters and disasters, serving as a basis for local implementation and enhancing capacity for natural disaster monitoring, forecasting and warning; improve the efficiency of information, propaganda, knowledge universalization for the people, training skills for forces to minimize damage when earthquakes and tsunamis occur.
