(April 21, 2013) The strong earthquake that struck China’s mountainous Sichuan province Saturday morning may have been an aftershock, says prominent Chinese geologist, Fan Xiao. The accumulation of stress had not yet been fully released, making this region a more dangerous area after the May 2008 Wenchuan earthquake.
(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.
Three years after the devastating 2008 Sichuan earthquake, geologist Yang Yong investigates the proliferation of hastily approved mining and industry projects putting the area at risk of further geological disasters.
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.
(July 14, 2010) Abstract: Two and a half years prior to China’s M7.9 Wenchuan earthquake of May 2008, at least 300 million metric tons of water accumulated with additional seasonal water level changes in the Minjiang River Valley at the eastern margin of the Longmen Shan. This article shows that static surface loading in the valley induced Coulomb failure stresses on the nearby Beichuan thrust fault system at <17km depth.
(November 18, 2009) Scientists have seen this one before: Fill a reservoir behind a new dam, and, oops, you trigger an earthquake nearby not long after the lake is topped off.
(November 6, 2009) A recent article by scientists in the U.S. provides further evidence that the Zipingpu dam’s reservoir may have triggered the devastating May 2008 Wenchuan earthquake in China. The Wenchuan earthquake killed nearly 90,000 people and unleashed a chorus of speculation that the Zipingpu reservoir may have contributed to the severity of the earthquake, or helped to trigger it.
(October 28, 2009) A new study published in the journal of Geophysical Research Letters provides more evidence that the deadly Wenchuan earthquake may have been triggered by the Zipingpu dam’s reservoir.
(May 8, 2009) The debate over whether the Zipingpu dam contributed to the severity or timing of last year’s deadly earthquake in China’s Sichuan province continues to attract attention. Fan Xiao, chief engineer of the Regional Geology Investigation Team of the Sichuan Geology and Mineral Bureau, was recently interviewed by Richard Stone for Science magazine.
(July 11, 2008) The numbers from the May 12 earthquake in China are staggering. As this edition of E&MJ went to press, the death toll in Sichuan Province had climbed to 68,000 with 288,000 injured and more than 5 million people homeless.
(July 1, 2008) An article published recently in the journal Nature provides in-depth details about the area where the Wenchuan earthquake hit and particularly the state of stress in the crust of the Earth in the area.
The 7.0-magnitude earthquake in southwest China’s Sichuan province earlier this month, and a devastating 2008 quake in the same province, are likely linked to the region’s dam-building program, says expert.
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.
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.
Chinese authorities are hoping a large-scale rollout of hydropower can help to reduce toxic smog but, in addition to the high financial and environmental costs, many experts are skeptical that more hydropower means less coal.
