Authorities in the southern Vietnamese province of An Giang have requested the relocation of 20,000 households due to the threat of increasingly serious subsidence along local rivers.
A delegation from the Ministry of Natural Resources and Environment convened a working session with authorities in An Giang on Tuesday evening, discussing the collapse of the Vam Nao riverbank that sunk at least 14 houses last weekend.
Speaking at the meeting, Tran Dang Duc, director of the An Giang environment department, said that the subsidence had affected an area 70 meters across and 35 meters into the riverbank.
The threat of further subsidence continues, with another 90 houses in the neighborhood at risk, Duc continued.
