More than 6,600 people in the central city of Da Nang on Tuesday tested their safeguards in an exercise responding to a six-meter tsunami triggered by an 8.8-magnitude earthquake.
The drill was carried out in Son Tra District's Tho Quang and Man Thai wards along the coastline and other inland locations.
The mock tsunami was forecast to hit the Da Nang coastline within three hours after an 8.8-magnitude earthquake shook the Luzon Island of the Philippines off the East Sea.
The scenario required the complete evacuation of 133,529 residents from 20 communes and wards in five coastal districts and 6,500 Vietnamese and foreign tourists who were resting on the beaches as well as in coastal resorts and hotels.
Around 75 vessels with 910 fishermen on board also needed to be brought to shelter.
After the Da Nang authorities were informed of the news from the Earthquake Information Center, the tsunami report was quickly sent to residents on inland locations and at sea.
Rescue forces began evacuating residents and tourists from coastal areas to higher places.
Under the scenario sketched for the rehearsal, after the tsunami hit Da Nang coastline, around 2,500 people were dead and missing, and 3,000 were injured. The waves also sank 150 vessels and destroyed 2,500 houses.
Ships, helicopters and specialized vehicles were sent to the coastal areas and the sea to rescue and evacuate people.
Police, border guard, militia, healthcare and Red Cross forces as well as residents were mobilized to search for missing people and care for injured people.
The first-ever tsunami drill was led by Deputy Prime Minister Hoang Trung Hai, chairman of the National Search and Rescue Committee.
According to the Ministry of Natural Resources and Environment, an 8.3 magnitude earthquake from the Philippines can create a tsunami 6.2 meters high in Quang Ngai Province and 2.1 meters high in Nha Trang, both to the south of Da Nang.
An earthquake of 9.2-magnitude from the same area can cause a tsunami 10.6 meters high in Quang Ngai and five meters in Nha Trang.
It would take around two hours for a tsunami from the Philippines to reach Vietnam's coastline, the ministry said.
