Rescue workers pulled a second woman to safety minutes later in the same place in rare good news in Sichuan province, where the official death toll has risen to nearly 15,000 from Monday's massive quake.

Safety officials could speak to Zhang Xiaoyan but had to proceed slowly in trying to dig her out for fear that the rubble above her would shift and collapse onto her.

"It is very moving. It's a miracle brought about by us all working together," said Sun Guoli, the fire chief of nearby Chengdu, the provincial capital.

"It's a miracle of life, using one's life to save a life," she said as she watched Zhang being taken away in an ambulance.

Sun was on the scene for the whole of the 50-hour rescue operation.

Zhang and the other woman were trapped about 18 feet high in a pile of concrete slabs and other debris after their building collapsed. Details on the other woman were not immediately known.

Both looked shaken but not seriously injured when they were pulled out. They had been given water during the whole time and rescue workers were able to talk to them.
