The Thursday landslide occurred in Phuoc Son District, about 200 km from Nam Tra My District, where two other landslides hit Wednesday, said Nguyen Quang, deputy chairman of Phuoc Son.

At least one person has been confirmed dead, with a further 10 still missing. All 11 people reportedly belong to the same family, Quang said.

"As communication broke down across the area, locals had to report the incident on foot to district authorities this morning," he said.

Police, soldiers and other rescue personnel have been dispatched to the difficult-to-access locality.

Also in Phuoc Son District, 25-year-old Ho Van So and 28-year-old Ho Van Do were confirmed dead after being swept away by a stream due to landslides and heavy rains Wednesday while surveying damage and evacuating people in the area.

Quang Nam has recorded several landslides since Wednesday due to impacts from now-devolved Storm Molave.

One occurred in Nam Tra My's Tra Leng Commune, burying 53 people, with 34 having been rescued, six bodies found and 13 still missing.

Another one struck Nam Tra My’s Tra Van Commune, killing eight and injuring 12.

The province’s landslide death toll as of Thursday afternoon stood at 15.

Molave, said to be the most powerful storm to hit Vietnam in the last two decades, uprooted many trees and damaged hundreds of houses and other structures. Some 56,000 homes had their roofs blown away.

The storm made landfall on Wednesday morning and weakened into a tropical depression by 4 p.m., according to the National Center for Hydro-Meteorological Forecasting.

Rainfall of up to 300 mm has been recorded in Quang Nam beginning 9 a.m. Wednesday.
