Four construction workers are dead and more than 50 missing after a landslide took out a dam project in China's Sichuan province.
It is the latest of a series of disasters caused by heavy rains in the area of southwest China.
Flooding along the steep mountains that witnessed last year's earthquake has brought more misery to survivors.
Local governments in Sichuan and Gansu provinces are sending tents and relief for a second time, as rains and floods displaced thousands of people.
The 12 May 2008 earthquake killed about 80,000 people, left 5m homeless, and severely weakened the steep slopes that front the fertile Sichuan plain.
Electricity was only just restored on Thursday to 80,000 people hit by floods last week in Longmen, southern Gansu province, according to official reports.
On Thursday, the heavy rains triggered a landslide at the Changheba hydropower plant in Kangding, temporarily blocking a river.
Up to 97 people trapped by the slide have been rescued, but at least 50 are still missing, according to the Ministry of Civil Affairs.
The rapid rivers of Sichuan are packed with hydropower dams, but moves are underway to stop construction of new dams in densely populated or environmentally protected areas, or in places where the geography 'lends itself to natural disasters'.
