China Earthquake a Dam-Induced Disaster?

(February 4, 2009) Last year’s devastating Sichuan earthquake, which took at least 69,000 lives, may have been unleashed by the huge Zipingpu Dam. New scientific evidence links the impoundment of the Zipingpu reservoir to the activation of a fault line near the dam site. A thorough scientific assessment is needed before China builds more dams in earthquake-prone areas.

Scientists build case that Zipingpu dam triggered China’s devastating earthquake

(January 28, 2009) Since China’s deadly May 12 earthquake, Fan Xiao, China’s chief engineer of the Regional Geology Investigation Team of the Sichuan Geology and Mineral Bureau, has been a lone voice calling for an investigation into the possibility that the Zipingpu dam reservoir, just a few kilometers from the epicenter, might have induced the earthquake.

Chinese scientists talk about the Zipingpu reservoir-triggered earthquake

(December 15, 2008) Top Chinese scientists from the Chinese Academy of Sciences have dismissed the possibility that the Zipingpu dam reservoir could have induced China’s devastating 2008 earthquake, complaining that the media has been “incessantly questioning the wisdom of building more and more hydro dams in earthquake-prone southwest China” in the wake of last year’s quake.

Integrated analysis of stress and regional seismicity by surface loading: a case study of the Zipingpu reservoir

(December 1, 2008) Probe International provides a partial translation of a Chinese geological case study of the Zipingpu reservoir authored by scientists from the government’s China Earthquake Administration. The study concluded that the 320 million tonnes of water in the Zipingpu reservoir had “clearly affected local seismicity” in the region and that, "it is worthwhile to further study if the effect played a role in triggering the Wenchuan earthquake."
