Dozens of land cracks and subsidence points
According to statistics as of September 19, dozens of land cracks, subsidence, and landslides have appeared in Lam Dong province in many localities.
In Bac Gia Nghia ward, the concrete road connecting National Highway 28 through residential group 10 Dak Ha has 8 cracks, 10-15m apart.
The crack is 15-20cm wide, 20-30cm deep, with locations up to 50cm deep. Some cracks extend into production land and adjacent fields, also showing cracks and local subsidence.
As of the time of reporting, no damage to people, houses and other works has been recorded.
The Ward People's Committee assessed that prolonged heavy rain caused the ground to be waterlogged, reducing stability; steep terrain and clay-shaped ground increased the risk of landslides.
In Quang Son commune, Dak Snao village area is affected by about 5ha, of which the subsidence area is about 4ha, with an average depth of 20cm. The cracks are about 300m long, 6-17cm wide and tend to expand.

On the night of September 17, 215 people including the elderly, women and children were taken to safe places. Functional forces have cordoned off, barricaded and placed warning signs at dangerous locations.
Recommend people to stay away from dangerous areas
According to initial assessment, the Dak Snao village area (Quang Son commune) needs to be surveyed and assessed by a professional consulting unit for the level of subsidence, landslides and the risk of continued fluctuations.
This is the basis for researching handling solutions, including plans to relocate and resettle households in the affected area.
In Dam Rong 4 commune, landslides occurred in Dung K'No 5 resettlement residential area. The People's Committee of Lam Dong province has announced an emergency situation for natural disasters; the locality relocated 13 households to a safe place.
In the Da Lat area, heavy rain caused landslides at Prenn Pass and D'ran Pass, affecting traffic.
In the Bao Loc area, many landslide points appear in Ward 3 Bao Loc and Ward B'Lao, in which the area adjacent to Loc Son Industrial Park is developing complicatedly.
In Cat Tien commune, landslides occurred in many locations along the Dong Nai River, posing a potential risk of affecting traffic roads, production land and housing.
Faced with heavy rain, functional agencies recommend that people limit crossing into areas with cracked soil, landslides, and subsidence; absolutely do not enter dangerous areas at night.
Mr. Doan Van Phuong - Chairman of Quang Son Commune People's Committee, said that the situation of landslides and subsidence in Dak Snao village is developing complicatedly and showing signs of spreading. The locality arranged forces to be on duty, and at the same time advised people to stay away from dangerous areas.
