The risk of tsunami with Vietnam will be very high?

The fact that an American scientist has just released a forecast that the risk of a new tsunami in Asia is worse than the 26 December 2004 raises the need to build a tsunami warning system in Vietnam.

This is also a controversial issue. Notably, the latest research shows that the risk of tsunamis for coastal areas in Vietnam will be very high if .

According to Dr. Ngo Thi Lu, Institute of Geophysics, only what happened, damage and catastrophic consequences of the earthquake with Andaman tsunami - Sumatra on December 26, 2004, also forced we must seriously answer the question of whether there is a possibility of a tsunami for the Vietnamese coast, what we need to do to reduce this risk (if any) .

In Vietnam, studies on earthquake regime in the East Sea and tsunami-forming conditions, forecasting capabilities to mitigate the damage they can cause have begun to appear in the 10 years ago.

According to many research papers of seismologists and domestic and international oceanographers, tsunamis occur less frequently and are not too dangerous in Vietnamese waters.

However, many studies have also shown, in the western Philippines (ie the eastern edge of the East Sea), each strong earthquake occurred with sufficient conditions to cause tsunamis such as large enough energy (M> 8). , the depth of the shock is small (h At the same time, there was also a tsunami.

On the other hand, GPS measurements of absolute displacement in Vietnam and Thailand show that the movement of Indochina to the east has a speed of 3 ± 0.2 cm / year. The shift of the Philippines to the west is not less than 8 cm / year. Thus, the relative movement speed between two arrays is not less than 10 cm / year.

This speed is greater than the speed of the submerged Indian plate under Burma. Therefore, if an earthquake capable of causing tsunamis occurs at the boundary between the Philippine Plate and the Asian Plate, the risk of tsunamis on the coast of Vietnam will be very high.

Therefore, conducting a review and study of earthquakes that can cause tsunamis affects the coast of Vietnam and find solutions to build systems and mechanisms for early warning of earthquakes and tsunamis to minimize The risk of damage caused by it can be extremely necessary for Vietnam and the surrounding areas.

Scientists have recorded stories about Vietnam's coastal disaster in the past 100 years despite their very thin accuracy. ' Can not be caught off guard by the tsunami risk ', Assoc. Dr. Vu Thanh Ca, Director of the Center for Research and Application of New Technologies, said Hydrometeorological Institute.
