Heavy rainfall triggering flash floods and mudslides have damaged roads, destroyed buildings and claimed bridges, wreaking havoc in China's southwestern Yunnan province on a long holiday weekend.
No casualties were reported but more than 4,800 residents in Gongshan county were affected, with about one-third of them urgently relocated, state news agency Xinhua said.
Over 600 tourists visiting rural scenic spots in the area on Saturday found themselves trapped, according to Xinhua, which reported 500 of them had been rescued by Sunday.
Road access to mountainous sites popular with hikers such as Bingzhongluo town and Yubeng village in neighboring Deqin county were cut off, state broadcaster CCTV.
The Dulong river saw flood waters swell to record levels, according to historical logs from a hydrological monitoring station.
A four-storey building set along the river that had been evacuated collapsed, CCTV reported, showing a video of the structure tipping backwards and disappearing into a cloud of dust.
The intense rainfall over a 12-hour period disrupted power supplies. Repair work to roads and power lines was underway, said state media.
Local authorities had issued a red alert ahead of the rainstorm on Friday night but downgraded it to a yellow alert by Saturday morning.
China uses a four-color warning system that escalates from blue, yellow, orange to red according to the level of precipitation and anticipated risks.
