An aerial view of Tangjiashan Lake, May 25, 2008. Formed after the May 12 earthquake in Beichuan County, Sichuan Province, the lake is a palpable threat to thousands of survivors. It now holds more than 128 million cubic meters of water, likely to cause extensive damage to life and property if the barrier bursts. Altogether 35 barrier lakes were formed by landslides after the May 12 earthquake, which has left 62,664 people dead and 23,775 missing. (Xinhua)
