Three Gorges Dam Project, Yangtze River, China

(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.

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.

Water brief: Three Gorges Dam

(January 1, 2009) In The World’s Water 2008-2009, the Pacific Institute’s Dr. Gleick examines the usual anticipated benefits of the Three Gorges Dam: power, navigation and flood control and the growing list of problems — serious impacts on fisheries, coastal erosion due to vastly lower sediment flow in the Yangtze, landslides, earthquakes and social unrest due to the displacement of millions of people.

New geomorphological index created for studying active tectonics of mountains

(June 3, 2008) To build a hospital, nuclear power station or a large dam you need to know the possible earthquake risks of the terrain. Now, researchers from the Universities of Granada and Jaen, alongside scientists from the University of California, have developed, based on relief data from the southern edge of the Sierra Nevada, a geomorphological index that analyses land form in relation to active tectonics, applicable to any mountain chain on the planet.

China’s dams in the danger zone

(June 4, 2008) CHINA is no stranger to natural disasters, but it has come a long way in how it deals with them. When a dam collapsed during a typhoon three decades ago, killing more than 80,000 people, it was several years before the outside world knew anything about it. Beijing’s reaction to last month’s earthquake in Sichuan, which is known to have killed nearly 70,000, has been refreshingly different.
