A massive boulder collapsed onto National Highway 279D in Son La.

A serious landslide occurred at 5:30 PM on August 6th at Km44+125 on National Highway 279D, in the Ta Sai hamlet, Chieng Lao commune, Son La province.

A massive amount of soil and rocks from the embankment collapsed onto the road, completely cutting off the vital transportation route connecting the highland communes. Among the debris were boulders weighing tens of tons. Fortunately, no vehicles were traveling through the area at the time of the landslide.

The Chiềng Lao commune authorities promptly mobilized forces and resources to address the issue. However, by evening of the same day, the road remained paralyzed, and residents and vehicles were advised to temporarily choose alternative routes.

Due to the ongoing rain, the risk of further landslides remains very high, especially on steep mountain passes and high mountain sections. Therefore, people must strictly adhere to traffic control instructions to ensure safety.

Landslides and soil cover the Noi Bai - Lao Cai expressway on the way back to Hanoi.

Earlier in Lao Cai province, a landslide also occurred at Km241+700 on the Noi Bai - Lao Cai expressway. Although this landslide point had been addressed a week ago, by the afternoon of August 3rd, soil and rocks continued to slide down after heavy rain, obstructing traffic towards Hanoi. The expressway operator implemented a traffic diversion plan, diverting vehicles via National Highway 4E and rejoining the expressway at IC17 (Xuan Giao interchange), while maintaining a presence at the scene to ensure safety.

The Department of Dyke Management and Disaster Prevention ( Ministry of Agriculture and Environment ) and meteorological agencies warn that localities in the northern mountainous region need to review residential areas and high-risk points along major transportation routes due to the increased risk of landslides during the rainy season.

According to the National Center for Meteorological and Hydrological Forecasting, from the night of August 5th to August 6th, heavy rain occurred over a wide area, especially in the northern mountainous provinces, ending a prolonged period of hot weather.

According to data from the Vrain automatic rain gauge system up to 6:30 PM on August 6th, the following localities experienced heavy rainfall: Dien Bien (108.2mm), Lam Dong (98.6mm), Can Tho (94.4mm), Son La (93.6mm), Bac Ninh (92.2mm), Lai Chau (89.8mm), Hai Phong (89.2mm), Khanh Hoa (85mm), Hanoi (81mm), Lao Cai (77mm), Cao Bang (76.8mm), Thai Nguyen (63.8mm), Quang Ninh (63.6mm), Tuyen Quang (60.2mm), and Lang Son (52.8mm).

Forecasts indicate that in Northern Vietnam, rain will continue from the night of August 6th to the afternoon of August 7th, then gradually decrease from the evening of August 7th. Southern Vietnam is also warned of the possibility of strong thunderstorms and tornadoes on the evening of August 6th and the afternoon and evening of August 7th.
