Is China’s hydropower safe? Bloomberg’s Adam Minter cites Probe International’s investigations into the link between China’s dam-building and the surge in earthquakes.
Yunnan earthquake raises fears on hydropower projects
Geologists express concerns that massive hydropower construction in the region may have contributed to seismic activity. Beijing-based media group, Caixin, interviews Chinese geologist Fan Xiao whose research supports a link between Yunnan’s 6.5-magnitude earthquake in early August and the filling of dam reservoirs in the area.
Landslide destroys dam in Three Gorges region
Geologists predict more frequent catastrophes in China’s Three Gorges Dam region, after landslides wipe out a hydropower plant. Fan Xiao and Yang Yong, the authors of several reports for Probe International, speak to thethirdpole.net about a disaster-prone region made more perilous by intensive hydropower development and call for new risk assessments to be carried out.
Chinese official disputes report linking fatal earthquake in Ludian and filling of reservoirs
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.
Chinese data hint at trigger for fatal quake
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.
Impoundment of two mega-dams on China’s Jinsha River triggers earthquake in Ludian
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.
China is being forced to choose between air pollution and deadly earthquakes
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.
Yunnan earthquake linked to dam-building, says Chinese geologist
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.
China quake reignites debate on country’s rush to build large dams
“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.
Quake strikes Three Gorges Dam area again
(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.
The probe of Three Gorges officials is getting too close for Communist Party leaders
(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”.
More quakes linked to mega-dams
(April 9, 2014) Another earthquake has struck China’s seismically hazardous southwestern region in the same vicinity as one of the country’s mega-dams. Chinese geologist and environmentalist Fan Xiao says there is a “high probability” the Xiluodu dam, China’s second and the world’s third biggest hydropower power plant, triggered the quake.
Three Gorges Dam triggers frequent seismic activities
(April 7, 2014) Chinese geologist and environmentalist Fan Xiao says the recent quakes that struck central China’s Hubei Province in Zigui county — “the first county of the Three Gorges Dam” due to its proximity to the project site — signal that the seismic threat posed by Three Gorges Dam is at its most critical stage now. Reservoir-induced seismicity (RIS) is most likely to occur within a few years, even a decade after initial filling of a dam reservoir to its highest level, due to the time it takes for reservoir water to penetrate deep into seismic faults and fissures before it triggers seismic activity. A 2010 study revealed seismic monitors around the Three Gorges Dam reservoir and in Hubei Province registered 3,429 earthquakes between June of 2003 (when inundation of the reservoir began) and December 31, 2009: a 30-fold increase in seismic frequency over the pre-dam period.
More earthquakes strike Three Gorges Dam region
(April 1, 2014) A magnitude-4.7 earthquake hit Zigui county in central China’s Hubei Province last Sunday, around 23 kilometres from the Three Gorges Dam site location, several days after a magnitude-4.3 tremor was felt early Thursday morning about 30 kilometres from the dam. Authorities say the dam was not affected but they are monitoring the situation. There have been no reports of casualties or property damage, although news coverage has noted an increase in Chinese experts who support the speculation that the project itself is the cause of local seismic activity.
Three Gorges Dam not affected by tremor
(March 28, 2014) Once again, an earthquake has hit the Three Gorges reservoir area and dam officials are reassuring the public that the world’s largest hydropower plant is operating normally. The epicenter of a 4.3-magnitude earthquake struck Zigui County, just 30 km from the Three Gorges Dam at 12:20 a.m. March 27, 2014. Stay tuned while Probe International investigates the cause and effect of this latest tremor.
