Wenchuan earthquake, China

This debris deposit was produced by slope failures during the 2008 Wenchuan earthquake, China. Since then, the risk of debris flow and avalanche has increased significantly.

In stark contrast to pure financial costs are social and psychological consequences that are hard to quantify but the effects of which will be felt for a long time after the disaster. The inundation of the tsunami in schools in the East Coast of Japan in 2011 and the collapse of school buddings after the Wenchuan earthquake in China in 2008 killed an entire generation of school chU-dren (Fig. 5). 

The 2008 Wenchuan earthquake of Mw = 7.9 in the Sichuan Province of China affected mountainous area where body of moxmtains has been deteriorated by the tectonic action. Slope failures produced natural dams (Fig. 15). The problem of the natural dams is the possibility of breaching and flooding in the downstream area. Therefore, it is important after big earthquakes in mountain regions to find the formation of natural dams and if a dam is subject to overtopping, erosion, and breaching to drain water as soon as possible. Empirically it is known that seepage and piping failure is rather rare in natural dams (Tabata et al. 2002).

On May 12, 2008, just one day before the symposium, a major earthquake measuring 8.0 on the Richter scale hit Wenchuan County in southwest China s Sichuan province. It is the biggest disaster in Chinese history. As many as 70,000 people died, 20,000 people were missing and millions of people became homeless. To express our sympathy and help the people in the earthquake area, the symposium participants benevolently donated more than 1200 US dollars during the symposium. On behalf of the Organizing Committee, 1 would like to thank all of the donors for their kind support to the people in earthquake area.
