WEIYUAN COUNTY, China —
A devastating flash flood triggered by intense rainfall has claimed at least 10 lives and injured 23 others after rushing through a scenic camping destination in northwest China’s Gansu Province, catching hundreds of weekend visitors off guard.
The disaster unfolded at Shuangshimen Scenic Area in Weiyuan County, Dingxi City, where a sudden surge of water tore through a narrow mountain valley, sweeping away vehicles, destroying campsites and leaving tourists scrambling to escape rising floodwaters.
Emergency crews continued search and rescue efforts as authorities assessed the damage and investigated the circumstances surrounding one of the region’s deadliest flash floods this summer.

Heavy Rain Triggered Rapid Flood Surge
According to local authorities, the flooding was caused by short-duration but extremely intense rainfall upstream of the scenic area.
The rainfall sent massive volumes of water rushing through a steep mountain gorge within a short period, causing the normally calm stream to transform into a fast-moving torrent.
Officials said the river, which is typically less than two meters wide, expanded dramatically to between 30 and 50 meters at the height of the flood, leaving little time for campers to react.
Because the campsite sits inside a narrow valley, many visitors were unable to evacuate before floodwaters overwhelmed the area.
⸻
Campers and Vehicles Swept Away
The flash flood struck during a busy weekend, when numerous families and outdoor enthusiasts had gathered along the riverbank.
Witnesses described a sudden wall of muddy water carrying rocks, tree branches and debris downstream with tremendous force.
Several parked vehicles were swept away, while tents and camping equipment disappeared beneath the rushing current within minutes.
Authorities confirmed that at least 10 people lost their lives, while 23 others suffered injuries ranging from minor wounds to more serious conditions requiring hospital treatment.
⸻
Large-Scale Rescue Operation Launched
China’s Ministry of Emergency Management quickly activated a Level-IV flood prevention emergency response, deploying specialized rescue teams to the disaster zone.
More than 305 firefighters, 68 rescue vehicles, rescue dogs and emergency personnel were mobilized to search the flooded valley.
Despite difficult conditions caused by fast-moving water, thick mud and scattered debris, rescue workers successfully evacuated more than 240 stranded people from the area and transferred them to temporary shelters.
Officials said rescue operations continued despite unstable weather and challenging terrain.
⸻
Mountain Terrain Increased the Danger
Emergency responders explained that mountain valleys are particularly vulnerable during periods of intense summer rainfall because runoff from higher elevations can accumulate rapidly.
Even when rainfall is localized, narrow gorges can funnel enormous volumes of water downstream within minutes, creating powerful flash floods with little warning.
Authorities are continuing to monitor nearby waterways as weather conditions remain unstable in parts of Gansu Province.
⸻
Investigation Underway
Local officials have begun investigating the sequence of events leading up to the disaster, including weather monitoring, warning systems and emergency response procedures.
No immediate indication of structural failure or other contributing factors has been announced, with authorities continuing to focus on rescue operations and assisting affected families.
Officials have also urged residents and tourists to avoid rivers, valleys and mountain recreation areas whenever heavy rainfall warnings are issued.
⸻
Why It Matters
Flash floods remain one of the most dangerous natural hazards in mountainous regions because they can develop within minutes, often leaving little opportunity for evacuation.
The tragedy in Gansu highlights the growing risks associated with extreme weather events during China’s annual summer rainy season and underscores the importance of early warning systems for outdoor recreation areas.

TAD Perspective
The Gansu campsite disaster serves as another reminder that natural attractions located in narrow valleys can become highly dangerous during periods of intense rainfall. As climate variability contributes to more frequent extreme weather events, authorities may face increasing pressure to strengthen monitoring systems, improve public alerts and enhance emergency planning for popular tourist destinations.
