Mining-related activity accounts for the most frequent cause of human induced seismicity, followed by water reservoir impoundment, according to The Induced Earthquakes Database – a comprehensive global review of all human-induced earthquakes.
Too many dams to look after
As China continues to embrace a new era of hydropower expansion, demand for dam inspection has outpaced the country’s supply of inspectors, ramping up safety fears for thousands of small- and medium-sized dams in China’s rural areas that have been “ignored”, reports Ecns.cn.
Trouble on the Yangtze
(December 19, 2012) A central government plan to dramatically increase China’s reliance on non-fossil fuels will derive two-thirds of that target from hydropower – “an increase on par with adding nearly one Three Gorges Dam a year,” reports Jane Qiu for Science magazine. In her article on over-development of the country’s river pulse, the once mighty Yangtze, Qiu looks at the threat China’s damming fever poses to river habitats and species, the calamity potential of dam construction in quake-prone regions and mounting criticism of China’s biased environmental impact assessment process.
Press Release: 80,000 deaths from 2008 Chinese earthquake was likely not an act of God, says new study
(December 12, 2012) A new study published by Probe International reveals a dangerous relationship between dam reservoirs and seismic activity.
Aftershock from 2008 Wenchuan quake hits Sichuan
(December 4, 2012) Experts say the tremor that jolted Sichuan Province last weekend is an aftershock of the killer quake that struck the province in 2008, linked to the Zipingpu Dam.
Mega-dams in China’s earthquake zones could have “disastrous consequences”
(October 31, 2012) “Earthquake Hazards and Large Dams in Western China,” the Probe International report authored by geologist John Jackson, has set China’s academic and industry circles astir. As the debate over Jackson’s findings heats up, the respected Caixin Media magazine, New Century Weekly, looks at both sides of the debate and the specific issues Jackson’s explosive report has raised.
(September 5, 2012) Probe International has been at the forefront of research on the connection between seismic activity and large-dam construction, focusing on examples in China such as the Zipingpu Dam, which is thought to have triggered the deadly 2008 Sichuan earthquake. Now, a new article by U.S.-based quake warning advocate, David Nabhan, calls for a rethink of seismic forecasting in North America that draws on connections so often overlooked: specifically, the trigger effect of dams, and the impact of lunar and solar gravitational tides on earthquake activity.
Chinese appeal for dams inquiry
(July 11, 2008) A group of Chinese academics and environmental activists call on the Chinese government to review the safety of large dam projects.

(May 30, 2008) Top political advisor, Jia Qinglin, has inspected quake-affected Yingxiu Town and Dujiangyan City. He asked locals about their living conditions after the earthquake.
China asserts conditions of dams are stable
