Impact of Rain-Induced Landslides on National Highways and Border Trade

The transcript details severe disruptions caused by rain-induced landslides across several key national highways in Vietnam, significantly impacting transportation, trade, and public safety.

1. Quốc lộ 14D: Severe Blockage and Economic Impact

• Location and Significance: Quốc lộ 14D, a 70 km stretch connecting the Ho Chi Minh Highway to the Nam Giang International Border Gate, is part of the East-West Economic Corridor 2.
• Current Condition: The highway is already in a degraded state and is described as the most dangerous national highway.
• Consequences of Landslides: Severe blockages due to landslides have halted traffic. This prevents border residents from buying and selling goods with lowland areas, affecting their livelihoods. Access to healthcare is also compromised.
• Economic Stoppage: Trade activities between the key economic region of the Central region and southern Laos and northeastern Thailand have been brought to a standstill.
• Immediate Action: Local authorities are implementing temporary repairs to ensure safe passage for border residents.

2. Quốc lộ 24: Landslide Damage and Traffic Restrictions

• Location: A significant landslide, approximately 100 meters long, has occurred on Quốc lộ 24, passing through the center of Mang Den Commune, Quang Ngai Province.
• Damage Details: The landslide has pushed up the road surface, damaging its structure and the rock embankment system designed to prevent landslides.
• Specifics of Road Uplift: The road surface has been pushed up by as much as 40 cm, with a bulge spanning 5.5 meters, narrowing the road.
• Traffic Management: Vehicles can only use the cut slope (ta luy âm) lane. Authorities have erected warning signs, barriers, and are directing traffic to operate on a one-way basis.

3. Da Nang: Search and Rescue Operations for Missing Victims

• Incident: A mountain landslide occurred in Hung Son Commune two days prior to the transcript's recording.
• Rescue Efforts: In addition to initial response teams, Da Nang City has deployed specialized forces to search for three individuals believed to be missing.
• Technology Used: Unmanned aerial vehicles (drones) are being utilized to scan mountain slopes and rugged terrain to identify potential signs of the missing persons. This aids in narrowing down search areas and guiding ground teams.
• Ground Operations: Search teams are divided into multiple units, using excavators and detection equipment to clear paths to suspected locations.
• Challenges: Rescue teams report that the landslide area has complex terrain, thick mud, and frequent water flows, making access difficult and dangerous.
• Current Focus: Search teams are working to take advantage of favorable weather conditions to expand the search area and ensure the safety of rescue personnel.

4. Hydropower Reservoir Management and Flood Preparedness

• Action by Dak Lak Province: Dak Lak Province has instructed the operators of the Ba Ha, Hinh, and Crom Hanh hydropower reservoirs to lower their water levels to the flood reception level by 11 AM on the day of the transcript.
• Flood Discharge Regulations: Reservoir operators are mandated to adhere to regulations when discharging floodwaters to prevent sudden floods that could impact downstream areas.
• Objective: These measures are in place to prepare for heavy rainfall, flooding, and the risk of flash floods.
• Rainfall Forecast: From the present until November 18th, heavy rainfall is predicted for the region from southern Quang Tri to Khanh Hoa, with rainfall amounts ranging from 150 to 300 mm, and exceeding 400 mm in some areas.
• River Level Warnings: Rivers in Gia Lai and Dak Lak are expected to rise to alert levels two and three.
• Agricultural Department Recommendation: The Department of Agriculture and Environment urges local authorities to strictly implement the "four-on-site" response plan, identify areas prone to landslides and deep flooding, and proactively evacuate residents.

Synthesis/Conclusion:

The transcript highlights the immediate and severe consequences of heavy rainfall and flooding in Vietnam, primarily manifesting as widespread landslides. These events have crippled critical transportation infrastructure like Quốc lộ 14D and 24, disrupting essential economic activities and daily life for affected communities. The ongoing search and rescue efforts in Da Nang underscore the human cost of these natural disasters. Proactive measures, such as reservoir management and the implementation of emergency response plans, are being undertaken to mitigate further risks, particularly in anticipation of continued heavy rainfall and potential flash floods in the coming days. The reliance on technology like drones in search operations and the emphasis on the "four-on-site" response plan demonstrate a multi-faceted approach to disaster management.
