Analysis of rough data by Chinese geologist Fan Xiao, cited by the prominent scientific journal Nature, connects heightened seismic activity to August’s Ludian earthquake.
Seismic activity started to rise just as two giant reservoirs on the upper Yangtze were being filled with water. Nature magazine reports on the latest findings by Chinese geologist Fan Xiao, published by Probe International, on the link between mega-dams and seismic activity in China’s southwestern region.
In the wake of the 6.5-magnitude earthquake in China’s Yunnan Province on August 3 that claimed the lives of more than 600 people, Chinese geologist Fan Xiao has released new data that supports a link between that event and the region’s mega-dams.
If the findings of Chinese geologist and environmentalist Fan Xiao – and the author of several reports for Probe International – are accurate, they raise a serious question. This report by Quartz, a business news site from Atlantic Media, looks at some recent quakes in China linked to the filling of hydro-dam reservoirs.
The environmental awareness of Chinese people has changed dramatically in the 25 years since her path-breaking book, Yangtze! Yangtze! on the environmental and social effects of China’s Three Gorges Dam, was published. Now, renowned journalist, author, activist and Probe International Fellow and correspondent, Dai Qing, sits down with the International Consortium of Investigative Journalists (ICIJ) for a look back on her experiences as a veteran reporter and the lessons of value she has learned along the way.
Already, newly completed cascade dams along China’s Lancang River are altering the river’s hydrological regime and sediment flow, blocking fish migration and posing a risk to food security and livelihoods. As more cascade dams roll out along the Lancang, International Rivers offers a better understanding through their research of the environmental impacts of current development and what further impacts can be expected as more projects come online.
The 6.5-magnitude earthquake that devastated southwestern China’s Yunnan Province on August 3 and killed nearly 600 is linked to the world’s largest and most intensive dam-building scheme on the Jinsha River, says renowned, independent geologist-explorer, Yang Yong.
“Why do earthquakes keep happening in that area?” In the wake of China’s 6.1 magnitude quake in Yunnan Province and a number of smaller quakes in the region, questions are once again being asked about the country’s rush to build big dams in its southwestern mountains, an area already vulnerable to seismic hazard.
Shanghai will suffer Three Gorges Dam impacts the most, says report.
An urgent overhaul of Three Gorges’ Dam management policy to enforce relevant regulations is needed to save various endangered species, improve the environment, and encourage economic development, say the authors of this paper. Xiankun Yang and X X Lu of the National University of Singapore discuss what we’ve learned from this controversial megadam over the past decade.
(May 28, 2014) Another earthquake has struck the Three Gorges Dam reservoir region in central China’s Zigui County. No casualties have been reported so far and officials say the dam is operating normally. The 3.4 magnitude tremor which hit early Monday morning, some 23 km from the dam, follows two earthquakes of magnitude above 4.0 and hundreds of aftershocks which shook the same region in late March of this year. The events rank as significant according to Chinese geologist and environmentalist Fan Xiao, who says they are signals that the seismic threat posed by Three Gorges Dam is at its most critical stage now.
(May 16, 2014) Lake Poyang, the largest freshwater lake in China, has in the past decade suffered record low water levels and its worst drought in 60 years. Although uneven rainfall patterns and industry on the lake are partly behind the decline in volume, the Three Gorges Dam has emerged as a major cause of the lake’s shocking dry-up. On a recent trip to China, Mu Lan, the editor of Probe International’s Chinese Three Gorges Probe news service, explored the link between Poyang’s crisis and the country’s hydro colossus.
(May 16, 2014) Mu Lan, the editor of our Chinese Three Gorges Probe news service, documents in pictures the decline of China’s largest freshwater lake on the southern bank of the Yangtze River in east China’s Jiangxi Province for his report, “Is the Three Gorges Dam to blame for extreme drought in the Lake Poyang area?”
(April 21, 2014) China’s roving corruption crackdown has uncovered nepotism, shady property deals and dodgy bidding procedures at the country’s state-owned Three Gorges Dam operator, Three Gorges Corporation. The news has reignited public anger over a project funded by a special levy paid for by Chinese citizens and has sparked speculation that President Xi Jinping is using Three Gorges as a way to target two of China’s biggest “tigers”.
(April 11, 2014) A report representing the most comprehensive economic analysis of large dams ever undertaken has dealt a stunning blow to the behemoths of hydropower. But will its findings be enough to curb a new wave in mega-dam construction? Unlikely, says Probe International.
