Local authorities confirmed that the landslide occurred shortly after 5am, following prolonged heavy rain.
A large volume of soil and rocks suddenly fell from Chut Mountain onto Tran Phu Street.
A 34-year-old woman was riding through the area when falling rocks struck her, knocking her off her motorbike and leaving her injured.
She was taken to hospital for emergency treatment.
According to the Khanh Hoa Emergency Medical Centre, the woman suffered injuries to her legs, knees and other parts of her body.
Her condition was reported to be stable following treatment, and she remained conscious and alert.
Large amounts of soil and rocks covered the road, obstructing traffic and making it difficult for vehicles to pass.
Authorities arrived at the scene, installed warning signs and directed motorists through the affected area.
Officers and soldiers from the Nha Trang Port Border Guard Station also joined local authorities in regulating traffic and clearing debris to ensure public safety.
