From date 10 to October 13, it brought historic amounts of precipitation to Central Vietnam, peaking at 90.16 inches (2,290 mm) in A Lưới (Huế),[9] 59.842 inches (1,520 mm) in Quảng Trị, triggered the historical flood.[10] Linfa hit the central region of the country, destroying a total of 382 houses and flooded 109,034 others In addition, its flood damaged 165.5 km of national highways and 140.1 km of provincial highways. The disaster caused big losses to agricultural production by destroying 6,989 hectares (17,270 acres) of rice crops and vegetable crops, and 2,141 hectares (5,290 acres) of aquaculture, whilst killing about 685,225 cattle and poultry.[11] On the night of 12 to 13 October 2020, when leading the rescue team of workers at a hydropower plant (Thua Thien Hue) to find missing workers buried in a landslide, Major General Nguyễn Văn Man was buried in another landslide with 12 people from the rescue team.[12] On October 15, 2020, their bodies were found by rescuers.[13] The storm left 105 people dead and 27 missing in Vietnam.[14]
