LAM DONG (VNS) — Four families living in houses close to a hydro-power plant reservoir in Central Highland Lam Dong Province have been evacuated after land they were built on suddenly started to subside.
The houses, in Tan Nghia Commune in Di Linh District, have been under threat for a week.
People's Committee Chairman Le Ngoc Chanh said the land started to sink around Gia Bac 2 hamlet, a few hundred meters away from Dong Nai 2 Hydro-power Plant's reservoir.
He told Viet Nam News that the earth movement had continued for a week as cracks extended towards the reservoir.
The largest, deepest, and longest cracks are 500 metres apart, more than two metres deep, and two kilometers long.
Nine houses in the area are reported to have cracked walls and damaged foundations.
Three of them collapsed completely and two others are said to be at risk.
The cracks have also destroyed 55 hectares of coffee planted by 16 local households.
"The incident is the third of its kind to occur in the district in three years," Chanh said. "But this is the worst."
According to local residents, land subsidence started after the reservoir began storing water three weeks ago.
"Provincial authorities will visit the commune to study the situation, and in co-operation with the communal administration, investigate the exact cause of the subsidence", Chanh said. — VNS
