Heavy rains and subsequent geological disasters have taken significant tolls across China this summer.
A rain-triggered mudslide hit Zhouqu in northwest China's Gansu Province on Aug. 8, leaving at least 1,435 dead and 330 missing.
Last week's mudslides in a remote mountain town in southwest China's Yunnan Province killed at least 32 people and left 60 missing.
Rain-triggered mudslides also killed at least 18 people in Wenchuan and Qingchuan counties in southwest China's Sichuan -- which is still recovering from the massive earthquake of 2008.
Heavy rain also wreaked havoc in northeast China's Liaoning Province as a major river bordering China and the Democratic People's Republic of Korea has swelled, forcing the evacuation of some 253,500 residents.
