Rescuers are searching for hundreds of missing people after a landslide in northwestern China left at least 337 people dead.
Nearly 1,150 people are missing after heavy rains created landslides that buried at least 300 low-rise homes in Gansu province.
The region is dominated by steep and barren hills.
Upstream from the disaster, demolition experts and geologists are working to drain a lake that had built up behind a barrier of landslide blockage.
With more rains forecast for this week, there will be fresh tragedy if the unsecured dam bursts, creating a new mud flow.
Chinese Premier Wen Jiabao visited the disaster-hit town for a second day in a row to survey the wreckage, promise government help, console survivors, and urge rescuers and engineers to work as hard as possible to save lives and prevent fresh tragedy.
6,000 troops, police and firefighters worked through the night to dig out survivors, though the depth of mud that devastated the worst-hit areas has dimmed hopes of finding many alive.
Over a metre deep in many areas, the mire has made it almost impossible for rescue teams to bring in vital heavy equipment.
Power lines are down in two-thirds of the county, and water up to four metres deep is still surging through some parts of town, the official Xinhua agency said.
At least 45,000 people have been evacuated, including the residents of downstream towns thought to be at risk from a fresh mudslide.
The Ministry of Finance has set aside 500 million yuan (€56m) in emergency funds for the region.
The Agriculture Ministry has also sent protective equipment and disinfectant to an area with large numbers of livestock - there are many nomadic Tibetan herders living there - to help battle possible epidemics caused by dead animals.
