Vietnam has downgraded Typhoon Noru to a tropical depression but warns residents to stay on alert because of the risks from flooding and landslides caused by heavy rain.
The storm made landfall in the early hours of Wednesday with winds of 117km/h in the province of Quang Nam, home to the historic city of Hoi An and resort of Danang, the weather agency told state media.
"I don't know if my roof has been torn down yet. The wind is just too strong," Le Thi Buoi, 70, said by telephone from a shelter in the coastal community of Tam Ky.
"You can hear it's roaring even inside this shelter."
There were no immediate reports of casualties but photographs posted on social media and on state media showed downed trees and mudslides blocking roads.
Noru was the strongest storm to hit the neighbouring Philippines this year and killed at least eight people when it made landfall on Sunday night, flooding farmland and communities and damaging crops, mainly rice.
Vietnam is also vulnerable to destructive storms and flooding because of its long coastline. Natural disasters - predominantly floods and landslides triggered by storms - killed 139 people and injured 150 others in the country last year, official data showed.
