Install 10 tsunami warning stations in Da Nang

The first 100 tsunami warning stations of Vietnam are researched and installed by Viettel and will be built in the central provinces in the coming time.

In the short term, from now to July 2011, Viettel will install 10 tsunami warning stations in Da Nang, which are likely to be affected by tsunamis.

Mr. Do Phong Doanh - Deputy Director of Viettel Da Nang branch confirmed the above information and said, with these warning stations, when the possibility of tsunamis occurs in the East Sea, through radio waves, people of the domain Central will be warned 30 minutes in advance.

The coast of Vietnam is likely to be affected by tsunamis (In the photo: Nguyen Tat Thanh Street - Da Nang was heavily devastated by the 9th storm in 2009)

Prevention of tsunami situations occurs

Assoc. Prof. Dr. Nguyen Hong Phuong - Deputy Director of Earthquake Reporting Center and Tsunami Warning - Geophysical Institute for Earth-physical disasters (earthquakes, tsunamis) in Vietnam: Vietnamese coast region Men are more likely to be affected by tsunami sources located inside the East Sea area .

The danger of our country is the deep trough of Manila in the western waters of the Philippines. This deep trough causes strong earthquake episodes and is likely to generate tsunamis that spread through the East Sea to Vietnam's central coast. Accordingly, a fault in the East Sea of ​​the Philippines could cause level 9 earthquakes and tsunamis.

Within 2-3 hours, tsunamis can hit Vietnam and the Central Coast is at greatest risk.

In Vietnam, according to the National Institute of Geophysics , in 1904 tsunamis hit Thua Thien-Hue, killing 724 people, destroying 22,000 houses. In 1964, tsunamis also "visited" Danang.

Facing the threat of tsunamis that can happen in Vietnam, at the end of 2009, the Government agreed to deploy 25 scenarios of warning of tsunami risk. Accordingly, scenario 4, earthquake in Manila fault zone (Philippines) 8.6 Richter scale is the chosen plan for planning construction, economic and social development as well as having immigration options when occurring. out tsunami. At that time, almost all of Da Nang's coastal area was flooded from 100 - 200m from the coast with the highest depth of 3m.

30 minutes to respond

Mr. Doanh said, in this April, the first 2 points out of 10 tsunami warning stations will be built at the top of Hoang Sa road in P. Man Thai-Son Tra and at the Information Regiment 575 in the area. Xuan Thieu - Hoa Hiep Nam - Lien Chieu.

At the two points above, there will be the highest receiving antenna from 30–35m. Besides, there is a siren system, a large capacity like the war time. The reason for having to install high voltage for better reception and further siren system. ' Immediately after there is a risk of tsunamis, these stations will collect waves, whistle systems will alert people to bathe, boats, coastal families know, urgently implement the prevention plan ', he Businessmen stressed.

Doanh added that the operating principle of tsunami warning stations is based on radio waves. That is, the system has been technically connected to the National Institute of Geophysics - a focal point for information and a tsunami warning system and links to information systems of other countries such as Japan and the US. to update the situation of earthquakes, aftershocks, tsunamis in the East Sea.

Through data analysis, the intensity if really at risk of tsunamis, the system seems to be immediately alerted to the coastal localities. People will have 30 minutes to manage when the tsunami hits.
