Zhouqu: Heavy rains on Wednesday lashed a remote section of northwestern China where weekend flooding killed at least 702 people, as hopes of finding more survivors faded and crews worked to stave off outbreaks of disease.
More than 1,000 people were still listed as missing in the disaster, with mud, stones and debris covering many houses.
The National Meteorological Center warned there was a "relatively large" chance of more landslides in the coming days, as the rain was expected to grow heavier, with up to 3 1/2 inches (90 millimeters) forecast for Friday.
With the chances of finding more survivors falling by the hour, troops and rescue teams joined by traumatized survivors turned to recovering bodies and seeing to the needs of the living. Clean drinking water was a primary concern, with most local sources destroyed or too polluted to use.
Entire communities in Gansu province`s Zhouqu district were swallowed up when the debris-choked Bailong River jumped its banks Sunday, releasing wave after wave of mud and rubble-strewn water. While torrential rains were the direct cause, tree cutting that left the dry hills exposed and the weakening of cliff faces by a massive 2008 earthquake were seen as contributing factors.
Buildings were torn from their foundations, their lower floors blown out by the force of the debris-laden water. Three villages comprising hundreds of households were entirely buried and much of the county seat left submerged.
Crews using explosives and excavators rushed Wednesday to drain an unstable lake on the Bailong upriver of Zhouqu, fearing more rain could cause a massive breach bringing more misery to the town.
Disinfectant crews in protective suits sprayed chemicals across the ground and over machinery, the smell of death heavy in the air. State media reported numerous cases of dysentery, while infected injuries, a lack of sanitation, clean drinking water and accumulating garbage increased the risk of typhoid, cholera and other diseases.
Rescue crews have been largely reliant on hand tools, with heavy equipment either unable to traverse the difficult terrain or mired in mud up to several yards (meters) deep.
But roads reopened Wednesday, allowing heavy earth-moving equipment and supplies to flow in.
At least 45,000 people have evacuated their homes, and the Civil Affairs Ministry reported the delivery of 7,000 tents and 21,400 blankets to the area, with thousands more on the way. Zhouqu has a population of 134,000, but it wasn`t clear how many needed emergency shelter.
Shen Si, a member of the Tibetan ethnic group native to the area, watched forlornly as troops dug to reach the bodies of her relatives inside their buried home.
"My mother and father in their 60s and my younger brother, all three of them, are buried here in our house still," she said.
Throughout the area, bodies were seen wrapped in blankets and tied to sticks or placed on planks and left on the shattered streets for pickup.
China`s leadership has ordered teams to continue the search for survivors, and the ruling Communist Party`s all-powerful Politburo Standing Committee met Tuesday to discuss rescue and relief work.
"It is now a critical time ... we must give the highest prominence to the protection of people`s lives and properties," it said in a statement.
Flooding in China has killed about 1,800 people this year and caused tens of billions of dollars in damage across 28 provinces and regions.
