(June 1, 2011) A study by seismologists at the China Seismological Bureau indicates that the massive Three Gorges dam on the Yangtze River caused a “significant” increase in seismic activity along the dam’s reservoir.
(May 19, 2011) Amid power shortages and potential catastrophe, China admits to failings in the Three Gorges Dam. Probe International Fellow Dai Qing responds from Beijing.
(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.
(March 2011) The giant structure located in China has already caused more than 3,400 (so far minor) earthquakes. Scientists are now warning that a much bigger disaster could be looming on the horizon. A study by seismologists at the China Earthquake Administration (formerly known as the China Seismological Bureau) indicates that the massive Three Gorges dam on the Yangtze River “significantly increased” seismic activity along the dam’s reservoir.
Effect of the Zipingpu reservoir impoundment on the occurrence of the 2008 Wenchuan earthquake and local seismicity
(October 2010) The occurrence of the 2008 May 12 Wenchuan earthquake (M 7.9) near the eastern edge of the Tibetan Plateau triggered a debate whether it was influenced by the newly impounded Zipingpu reservoir, located only about 21 km east of the earthquake epicentre.
(April 4, 2010) Abstract—With more and more reservoirs have been and are being built all over the world, reservoir-induced earthquake has received a great deal of attention from geoscientists mainly because of its potential to damage constructions and to cause human losses. Based on the previous researches on the environmental conditions of reservoir-induced earthquake, a criteria hierarchy model has been constructed.
(May 14, 2009) Last year’s earthquake in China is a salutary reminder about preparing for risk in the face of uncertainty.
(May 25, 2005) Globally, about one hundred sites are known where filling of artificial water reservoirs triggered earthquakes. It is noteworthy that a majority of the sites where triggered earthquakes exceeding magnitude 5 have occurred are in Stable Continental Regions.

(December 1999) Large dams can trigger earthquakes. The first observation of possible RIS was noted for Algeria’s Quedd Fodda Dam in 1932; the first extensive study of the correlation between increased earthquake […]
(1998) A review of case histories of reservoir-induced seismicity (RIS) in China shows that it mainly occurs in granitic and karst terranes. Seismicity in granitic terranes is mainly associated with pore pressure diffusion whereas in karst terranes the chemical effect of water appears to play a major role in triggering RIS. In view of the characteristic features of RIS in China, we can expect moderate earthquakes to be induced by the construction of the Three Gorges Project on the Yangtze River.
(1997) In most cases of reservoir-induced seismicity, seismicity follows the impoundment, large lake-level changes, or filling at a later time above the highest water level achieved until then. We classify this as initial seismicity. This ‘‘initial seismicity’’ is ascribable to the coupled poroelastic response of the reservoir to initial filling or water level changes.
Review of seismic-hazard issues associated with the Auburn Dam project, Sierra Nevada foothills, California
The potential for reservoir-induced seismicity, which is the triggering of earthquakes by the physical processes that accompany the impoundment of large reservoirs, was recognized during the seismic hazard studies for the original Auburn Dam. It remains an important issue for the present project because of the potential to increase the probability of earthquakes near the dam.
(April 9, 1994) The earthquake that killed 10,000 people in India last September struck within 15 kilometers of a reservoir filled just 2 years earlier. That proximity in time and space seems more than coincidental to two U.S. seismologists who propose that filling the reservoir may have set off the quake.
