(February 2, 2009) The devastating earthquake that killed 80,000 people in China’s Sichuan Province last May may have been triggered by a recently built hydropower dam that lies only three miles from the quake’s epicenter, some researchers are arguing.
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 geologist says Zipingpu dam reservoir may have triggered China’s deadly quake, calls for investigation
(January 26, 2009) Fan Xiao, Chief Engineer of the Regional Geology Investigation Team of the Sichuan Geology and Mineral Bureau, says scientists must investigate if Zipingpu dam triggered devastating 2008 earthquake, describes massive quake-damage to dams, rebuts recent Science Times article.
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.
FACT SHEET: Earthquake Fatalities High in 2008
(January 6, 2009) The number of earthquake-related fatalities across the world was much higher in 2008 than in recent years.
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.
China quakes, but the dams don’t break
(December 28, 2008) The biggest potential disaster, Pearce reports, was averted at the Zipingpu dam, just 17 kilometres from the quake’s epicenter. “Holding back more than a cubic kilometer of water … the hydroelectric dam was the largest of a new, cheap design with a rock core and concrete face. As the tight valley sides juddered, the structure was squeezed and ended up 18 centimeters downstream, and 70 cm lower. … The concrete was ripped apart but the core of the dam survived.”
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."
Study on Methods of Reservoir Induced Seismicity Prediction of the Three Gorges Reservoir”
(October 17, 2008) Based on the analysis of seismogeological background, the Three Gorges Reservoir area is divided into 31 units according to different combined conditions of induced earthquake, together with 8 influencing factors, to give the prediction on probability and magnitude of RIS by adopting statistical prediction model, fuzzy mathematics and gray system model as well as artificial neural network model respectively.
Pulling the trigger on RTS
(October 3, 2008) The International Commission on Large Dams (ICOLD) has published a new informative bulletin on reservoir triggered seismicity.
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.
Major flooding risk could span decades after Chinese earthquake
(September 7, 2008) Up to 20 million people, thousands of whom are already displaced from their homes following the devastating Chinese earthquake, are at increased risk from flooding and major power shortages in the massive Sichuan Basin over the next few decades and possibly centuries.
Quake survivors now face threat of flooding from damaged dams
(September 4, 2008) An earthquake of magnitude 6.1 hit Sichaun province last Saturday, killing at least 38 people and displacing 1.09 million, reports the South China Morning Post.
Opinion, suggestion sought for post-quake rebuilding
(August 16, 2008) A few days ago, the State Overall Planning for the Post-Wenchuan Earthquake Restoration and Reconstruction (Public Opinion Soliciting Draft) started to solicit opinions from home and abroad. An official was interviewed by the press and answered the questions regarding the public opinion solicitation.
