Central Vietnam
On the afternoon of 12 September, torrential rain swept central Vietnam, prompting a series of landslides and flash‑flood hazards in Quảng Trị province and the city of Đà Nẵng. In Trường Sơn commune, Quảng Trị, a large rock‑and‑soil mass fell onto the rescue road linking the commune with Trường Ninh, obstructing traffic. Local authorities secured the site, installed barriers and warning signs, and urged residents to avoid the route while heavy rain continued. Similar blockages were reported on bridges in the mountain districts of La Lay, A Dơi and Đakrông, where rising waters cut off connections to the lowland areas.
Đà Nẵng
In Đà Nẵng, the military command reported two separate slides in Trà Vân commune, each involving roughly 10 m³ of earth and rock that damaged a livestock pen and a section of national road DH5. Troops quickly cleared debris, set up safety ropes and signage, and assisted affected households. A further slide on DH6 in Sơn Cẩm Hà was also cleared, and a routine inspection in La Dêê found no new instability. Meanwhile, in Hùng Sơn commune, a massive slide along the road from the Triều Linh junction to Atu village buried the carriageway, rendering it impassable and prompting a warning against travel until conditions improve.
Central Vietnam Hydrometeorological Center
The Central Vietnam Hydrometeorological Center issued a six‑hour flood‑risk alert for Đà Nẵng, citing rainfall totals as high as 154.2 mm at Hương An bridge and over 150 mm at several other sites. Authorities have activated 24‑hour monitoring, deployed civil‑defence units, and ordered the "4 tại chỗ" (four‑at‑the‑site) preparedness plan, including rescue teams, equipment and evacuation protocols for vulnerable low‑lying and coastal zones. All measures aim to safeguard lives and restore transport links as the heavy rain persists.
