Major U.S. media report on theory that the deadly Sichuan earthquake was man-made

(February 18, 2009) As speculation has grown over whether the Sichuan earthquake, which killed 80,000 people last May and left more than 5 million people homeless, was triggered by the 315 million tonnes of water held in the Zipingpu dam reservoir, so too has press coverage of that theory. Here, Probe International provides a roundup of what that coverage is saying.

(2008) Large reservoirs can cause seismic events as they fill and as the pressure on local faults increases. Such reservoir-induced seismicity was predicted for the Three Gorges region, which is already seismically active and indeed, there has been an increase in reported seismic activity in the region following construction of the dam and the filling of the reservoir.

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.

Columbia geophysical hazards scientist says evidence shows dam reservoir likely triggered China’s great quake of 2008

(January 26, 2009) Christian Klose, a geophysical hazards research scientist from Columbia University in New York, says geophysical data suggests that the Zipingpu dam reservoir — just a few kilometers from the epicenter of China’s great quake of 2008 — likely triggered the deadly quake and explains how it happened.
