Earthquake survivors climb up a rocky embankment after arriving on a boat from areas inaccessible by road at the Zipingpu Dam near Dujiangyan, southwestern China’s Sichuan province, Friday, May 16, 2008. China warned the death toll from this week’s earthquake could soar to 50,000, while the government issued a rare public appeal Thursday for rescue equipment as it struggled to cope with the disaster.
