Since the impoundment of the Three Gorges reservoir began in 2003, tens of thousands of earthquakes have been recorded in the reservoir area. Chinese geologist and environmentalist, Fan Xiao, looks at the […]
Green projects may induce earthquakes
(March 25, 2011) The April edition of the popular technology, engineering, and science news magazine, IEEE Spectrum, describes how “green” projects — geothermal energy, hydropower and carbon sequestration — may induce seismic activity.
China to map active faults following a string of quakes in Asia
(March 25, 2011) The Chinese government will launch a campaign to map the country’s active fault lines in the wake of strong earthquakes in Japan and Myanmar.
Building Jinanqiao Dam

Dams damaged in Yushu earthquake
(May 22, 2010) The April 13, 2010 Yushu earthquake damaged three dams on the Batang River, putting one at risk of collapse.
The relationship between large reservoirs and seismicity
(January 2010) Following the 12 May 2008 Wenchuan earthquake in China, Chen Houqun, Xu Zeping and Li Ming discuss the question of whether large reservoirs can trigger strong earthquakes.
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.
Taking up the call…improving Seismic dam safety.
(March 1, 2002) We cannot ignore the call for increasing the safety of existing dam projects, says Martin Wieland, chairman of ICOLD’s Committee on Seismic Aspects of Dam Design. If we do, opponents of new dams will use concerns over earthquake safety to their advantage.
