Central Vietnam can be tsunami over 10m

'Quang Ngai and Nha Trang are at risk of tsunamis higher than 10 meters if a strong earthquake occurs in magnitude 9.2 in the Manila deep water trench' - Dr. Le Huy Minh said at the test of the alarming alarm system Tsunami newspaper held on May 15 in Da Nang.

Assuming 8.8-magnitude earthquake causes tsunami

The hypothetical situation set out at the trial was the western Philippines (1,800 - 2,000 km from our central region), which appeared 8.8 magnitude earthquake causing tsunami and expected within 2 hours after the wave God will enter Central.

The Information Regiment soldiers 575 evacuation drills at the test.

Upon receiving the above information, within 2 minutes, the Institute of Geophysical Physics broadcast earthquakes at the Center for Earthquake and Tsunami Information Reporting; At the same time, at the watch stations warning tsunamis, the siren system will signal.

At the same time, earthquake information is sent to mobile subscribers according to the pre-prepared directory, then transmitted to the radio system within a radius of about 2km (for warning towers) and through the system. Available radio transmissions of districts, wards and wards.

After 8-10 minutes, the second newsletter about tsunami warnings will be broadcast, requested to move and evacuate, and send a second message to mobile subscribers and radio stations. Evacuation work will be responsible for the army force. Next is the third issue of the security report via the SMS system and public radio, the watch station warning the tsunami.

After the trial, Deputy Prime Minister Hoang Trung Hai highly appreciated the coordination between the Ministry of Agriculture and Rural Development and the Military Telecom Corporation (Viettel), which soon put the system of watch stations to alert tsunami in Da Nang to try. experience.

'The two units need to build up a specific project on tsunami warning system nationwide to soon deploy, minimize the loss of people and when tsunamis occur' - Deputy Prime Minister Hoang Trung Hai stressed.

In addition, Deputy Prime Minister asked Viettel to expand the area of ​​receiving tsunami messages to all mobile phones in areas at risk. At the same time, it is necessary to connect the tsunami warning system to flood and storm prevention to inform and relocate people to achieve the highest results.

The risk of tsunami in Vietnam is existing!

According to Dr. Le Huy Minh (Institute of Geophysics - Vietnam Academy of Science and Technology), there has not been any convincing evidence to confirm the tsunami that affected Vietnamese waters.

However, according to the research results of the Institute of Geophysics, there are 8 earthquake sources in the East Sea and the surrounding area can cause tsunamis affecting Vietnam, including Riukiu (Taiwan), submerged zone Manila, Sulu Sea, Celebes Sea, Ban Da Sea, North East Sea, Palawan and West East Sea.

'Earthquakes with magnitudes greater than 6.5 on the Richter scale in these waters are likely to cause tsunamis in the Vietnamese coastline, ' said Dr. Minh.

The highest risk is the Manila submerged zone. The magnitude 8.3 earthquake here can create a high tsunami of 5.2m in Quang Ngai and 2.1m in Nha Trang. If the magnitude is 9.2, the tsunami in Quang Ngai will be 10.6m high and 5m in Nha Trang. Tsunami from the deep Manila trench to the Vietnamese coast takes about 2 hours after the earthquake. Recently, on May 26, 2006, this area had an earthquake of 8.2 on Richter scale but unfortunately did not cause tsunami.

Associate Professor, Dr. Nguyen Hong Phuong (Institute of Geophysics) also said that despite being less vulnerable to earthquakes, the territory and territorial waters of Vietnam exist complex faults, such as: Lai Chau - Dien Bien, Ma, La, Red, and Ca rivers .

From the beginning of 2011 until now, there have been nearly 10 earthquakes in Vietnam, such as 4.7-magnitude earthquake in Vung Tau-Phan Thiet offshore on January 27 and March 6, earthquakes smaller than 4, 2 Richter levels in Lai Chau on 25, 26 and 28 April. The most recent is the magnitude 4.2 earthquake in the Ma River area (Son La).

Dr. Le Huy Minh presented the risk of tsunami in Vietnam

Viettel said that by this time, a test system of 10 tsunami warning stations has been built in Da Nang City, in which 2 stations at 2 stations of Son Tra Border Guard Station and 575 Information Regiment, 2 stations Automatic alerts at Radio Station of Ngu Hanh Son District and Lien Chieu District, and 6 semi-automatic stations in Furama communes, wards and hotels.

In addition, Viettel also successfully connected the system to receive tsunami warning information from the Institute of Geophysics with centralized control and alarm management system in Viettel.
