(June 26, 2003) ‘The real danger comes from active faults in the vicinity of the dam site,’ which is located near six fault lines, a senior engineer warns in a recent Chinese newspaper report.
(July 31, 2002) Geologists fear the weight of the world’s tallest building may have transformed a stable area into one susceptible to seismic activity. But compared with dams, they say, buildings such as Taipei 101 are mere pinpricks on the Earth’s surface.
(July 23, 2002) The 385 aftershocks that followed the Nov. 26 Jiangxi earthquake have opened cracks, some about three inches wide, in the Jiujiang embankment, Epoch Times reports.
(July 11, 2002) Building yet another dam could threaten an ages-old engineering marvel in Sichuan and a key part of China’s heritage. But the project is going ahead as authorities smother public debate on its impact.
(May 9, 2002) Large dams in mountainous regions could threaten people living near them by stressing the Earth’s crust to danger levels, a scientist says.
(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.
(January 4, 2002) An earthquake with a magnitude of 4.1 shook an area 40 kilometres upstream of the Three Gorges dam last month, the Three Gorges Project Daily (Sanxia gongcheng bao) reported.
(February 16, 2001) A study written by Dr. Paul Burton and Steve Cole from Benfield Hazard Research Centre describes historical Chinese earthquakes and Chinese efforts in predicting earthquakes.
(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 […]
(August 7, 1998) As China’s worst Yangtze flood in half a century hits, the government must decide whether to submerge poor rural districts in order to save large cities like Wuhan. Environmentalist Dai Qing says the Three Gorges Dam would not help.
(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.
(November 1, 1997) Electricity industries worldwide are undergoing a period of profound upheaval.
(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.
