A million on evacuation alert in quake zone

Chinese authorities prepared to begin draining a swelling earthquake-formed lake today after evacuating nearly 200,000 people and warning more than a million others to be ready to leave quickly.

The lake, called Tangjiashan, formed above Beichuan town in the Mianyang region of Sichuan province when a hillside plunged into a river valley during the May 12 quake.
