The typhoon made landfall in Haiphong and Quang Ninh provinces, triggering winds of more than 149 km/h as it passed through southern China, where it killed 2 people.
In Haiphong, large metal plates and advertising signs were seen flying in the sky above the city when the typhoon hit.
"I haven't witnessed a typhoon this strong in years. It was scary. I stayed indoors after locking all the windows. However, the sound of the wind and rain was incredible," said Tran Thi Hoa, a 48-year-old woman from Haiphong.
The typhoon hit Vietnam after killing at least two people and injuring 92 others on the southern Chinese island of Hainan.
State broadcaster CCTV said Yagi had brought winds of more than 230 km/h, uprooted trees and forced the evacuation of about 460,000 people.
In the summer and autumn, southern China is often hit by typhoons that form in the warm oceans east of the Philippines and Thailand.
According to a study published in July, typhoons in the region are now forming closer to the coast, intensifying faster and lingering over land longer due to climate change. | BGNES
