In the last few decades, landslides have often occured in the mountainous areas of the coastal provinces in Central Vietnam during the rainy season. Typically in 1999, the torrential rainfall and flood caused the landslide over large areas of Quang Trị,Thua Thien Hue, Quang Nam, Quang Ngai, Binh Dinh provinces. About 40 people were buried under soils and rocks. Hundreds families had to move to the other places. In Quang Ngai, about 3.400 hectares of the rice field were buried by landslide debris of 1 m thick in average. The South-North transportation (both railway and road) had been blocked up for many days. This paper presents an overview on the landslides occurred, conditions and possible causes to trigger landslide in the mountainous areas of some coastal provinces in the central part such as Thua-Thien Hue, Quang Nam, Quang Ngai provinces. Some counter measures for landslide hazards management are also mentioned |
