Landslide concerns during rainy season

The cause of landslides is due to rising flood water creating strong currents, causing erosion on both banks and the bottom of rivers, canals and streams. On the other hand, due to weak soil, steep river banks and canals, and strong waves created by passing water vehicles... increasing the risk of landslides.

Head of the Department of Agriculture and Environment of Cho Moi district, Nguyen Thi Thuy Hau, said that the entire district has 150 landslide sections, 6,893m long, that have not been reinforced, with a total cost of about 160 billion VND.

Recently, on May 18, in Long Quoi 2 hamlet, Long Dien B commune (Cho Moi district), a landslide occurred on the riverbank, affecting 10 houses. The landslide was in the area of ​​Ong Chuong canal bank, on Provincial Road 946, in Long Dien B commune, about 100m downstream from Tra Thon bridge (towards Long Xuyen city). The landslide was about 70m long, eroded about 3m, the section at risk of being affected was about 200m long and affected 10 houses (the back part of the house fell into the river), the total estimated damage was about 2 billion VND, fortunately there were no casualties.

Current status of landslide area

Immediately after the landslide, Cho Moi district mobilized forces to urgently evacuate people from the dangerous area; support the relocation of assets; build fences, support people 2 million VND/household; people agreed to evacuate from the dangerous landslide area.

Chairman of Cho Moi District People's Committee Cu Minh Trong said: "The initial cause was determined to be due to the influence of the flow, this section of the river has many sharp bends, and is often affected by large-capacity boats and ships passing by. This section had a 30m landslide at the end of May 2023, and has not been included in the landslide warning of the Department of Agriculture and Environment. However, Cho Moi District People's Committee has updated it to include it in the landslide monitoring list and estimated the cost of repair"...

Ong Chuong canal connects Tien and Hau rivers, 23km long, flowing through Cho Moi district. This is also a river branch that often experiences landslides. The landslide happened very quickly, the entire row of 10 houses collapsed into the river, people fled into the street. Not yet over the shock, Ms. Le Thi Le (48 years old) shared: “When the house collapsed, my husband and 2 children went to work, only I was at home and my 12-year-old son was sleeping. Seeing the house collapse, I pulled my son up, screamed and ran out of the house. Now remembering that scene is still terrifying”. Mr. Nguyen Van Chu added: “I have lived here for nearly 40 years, just renovated the house for more than 300 million VND, built a wall on the land, made a wooden floor 11m out to the river. My grandparents have lived here for more than 80 years, this is the first time they have seen such a landslide, the entire floor collapsed into the river in a split second”...

Vice Chairman of An Giang Provincial People's Committee Ngo Cong Thuc surveyed the Long Dien landslide area.

Ms. Le said: "A few days before, there were cracks in the walls and floors that creaked day and night. Suspicious, the family moved their belongings out of the house first, so there was not much property damage. No land, hired labor, borrowed nearly 100 million VND to repair the house, the debt has not been paid off yet, now the house has collapsed, we cannot live in it. My family hopes to receive support from the State to provide a house to protect us from the sun and rain". Mr. Nguyen Ngoc Hiep (born in 1963) also shared: "Having a house that has collapsed is very difficult, we can only take a few sets of clothes, the items in the back are still intact, we do not dare to go in to get them. We hope to have a resettlement place to live safely"...

Conducting a field survey at the landslide section of Long Quoi 2 Hamlet, Long Dien B Commune, Vice Chairman of An Giang Provincial People's Committee Ngo Cong Thuc assessed the seriousness of the landslide. Thereby, he requested the Department of Construction and the Department of Agriculture and Environment to survey and re-evaluate the situation to have solutions to handle and overcome the landslide in the short and long term, especially in the coming rainy season, to ensure the safety of people's lives and property; survey the traffic volume of waterway and road vehicles, regulate the load of vehicles appropriately when passing through this landslide section. At the same time, re-evaluate the flow and place warning signs of landslide risks. In particular, local authorities urgently take care of the social security of affected households and quickly coordinate to consider supporting resettled households...

In order to proactively respond and minimize damage caused by landslides on riverbanks, canals and landslides on hills and mountains, Chairman of the An Giang Provincial People's Committee Ho Van Mung has requested to closely monitor meteorological and hydrological forecasts and warnings to promptly inform and disseminate information to local authorities and people. Check, review and prepare plans to proactively respond when situations arise.
