Water from a "quake lake" rushes through the earthquake-devastated city of Beichuan, located around 150 km (93 miles) north of Chengdu in Sichuan Province, June 10, 2008. Local witnesses said water levels in the river running through Beichuan rose dramatically this morning after People's Liberation Army (PLA) soldiers continued yesterday to try and ease the pressure on swollen "quake lakes" located above the town. More than 30 quake lakes formed when the May 12 earthquake triggered landslides that blocked rivers, raising fears of a secondary disaster after the tremor that killed more than 69,000.
