Steering activities for coping with floods and for emergency assistance to overcome the effects of floods
To prepare for rains and floods:
Forecasting and warning information of rains and floods have communicated widely on media but due to the topographical characteristics of the Centre combined with high rain intensity, floods have rapidly occurred and caused serious damage in Central Provinces.
When floods occur, the State and the Government of Viet Nam have pushed into efforts and proposed the measures for coping with the effects of floods as following:
To urgently, by every means, organise to rescue and evacuate people to safe havens.
To organise for supplying food and medicine for people in flooded areas who can not evacuate; and supplying food, essential commodities, medicine for people evacuated and blocked on roads.
To mobilise armed force, police force, and militia force to protect human and property, and social security. Armed force of the Military Zones Nos. 4 and 5, air force, naval force, and police force have been mobilised to relieve the most flood-affected areas, particularly in Thua Thien Hue Province.
To prepare food, medicine, shelter to re-settle the living for local people when floods go down.
To mobilise the assistance of people all over the country to relieve the affected people in flooded areas.
Emergency Aid Relief Activities
The Government of Viet Nam has assigned the Ministry of Defence for organising the air routs of Gia Lam-Vinh-Da Nang-Phu Bai and Tan Son Nhat-Da Nang-Phu Bai to deliver aid to flooded areas.
Viet Nam Central Father Land Frontier Committee in co-operation with Aid Reception and Management Board of the Ministry of Finance and Viet Nam Red Cross have received and delivered aid to Gia Lam, Tan Son Nhat, Da Nang, Chu Lai Airports.
