A fishing vessel from Gia Lai Province carrying eight fishermen has also been out of contact since September 27.
The typhoon caused severe damage to houses, crops and infrastructure across many provinces and cities, stretching from the northern mountainous region to central Viet Nam.
Specifically, 91 houses collapsed, 144,700 were damaged, and another 20,100 were submerged.
More than 34,000 hectares of rice and other crops were destroyed, while 1,100 head of livestock and 179,000 poultry were killed or swept away. Nearly 10,000 hectares of aquaculture farms were also ruined.
Over 6,400 electricity poles were knocked down, disrupting power supply to nearly 2.7 million customers in Thanh Hoa, Nghe An, Ha Tinh, and Quang Tri provinces. Power has since been restored to 1.38 million customers.
The telecommunications network was also severely affected, with more than 1,800 cellular towers partially losing service. However, no communes were completely cut off. More than 19 kilometres of river and coastal embankments were eroded.
Due to the impact of Typhoon Bualoi, 42 flights were cancelled and a further 51 delayed.
In the capital Ha Noi, heavy rains triggered by the typhoon’s remnants caused widespread flooding across the city, with water levels reaching up to one metre in many locations.
Preliminary estimates put the total economic loss at over 8 trillion VND (303 million USD), with Ha Tinh Province suffering the heaviest damage at about 6 trillion VND.
